毕业论文是一种有准备、有计划、比较正规的、比较重要的检验大学学习成果的形式,这里总结一下关于如何说答辩结尾的套路:
1、学生要讲述清楚自己对论文内容和创作过程的看法,写的时候,要将优缺点说明白。没有一位学生的论文是没有缺点的,写结束语的时候,要写明白自己对论文的看法,可以从不同角度去了解和观看,写的时候要清晰。
2、学生要将论文里面表达不足的地方,做出相应的改正。论文出现并不理想的话语,却在快要结束的时候才发现,学生需要将自己觉得不足的地方补充完整,或者提出新的想法,这都是可以的。
3、学生要感谢老师的帮助和引导。毕业论文并不只是学生的创业,在学生遇到不懂的地方,老师也会给予相应的帮助和引导,对于学生来讲,老师的帮助就是创作论文的一条思路,所以,学生要感谢老师。
示例说明:
最后,我想谈谈这篇论文及自己存在的不足。由于自己学识浅薄,认识能力不做,对某些问题的理解上有诸多偏颇和浅薄的地方,也由于理论功底的薄弱,存在有不少逻辑不畅和词不达意的地方,许多问题还有待于进一步思考和探讨。
借此答辩机会恳切的希望各位老师能够提出宝贵的意见,多指出本设计的错误和不足指出,我讲虚心接受,从而进一步深入学习研究使该设计得到完善和提高。以上是我的答辩自述,敬请各位评委老师提出宝贵的意见,谢谢!
毕业论文答辩结束语
毕业论文答辩结束语,时间过得很快,转眼间又到了毕业季,积极有很多学子走进职场,在毕业前大家都要通过最后的毕业论文来检验自己的学习成果,为了方便大家,下面我就来分享一下毕业论文答辩结束语。
结束语
在做这个设计的过程中,我尽可能多的收集资料,从中学到了许多有用的东西,也积累了不少经验,但由于自己学识浅薄,认识能力不足,在理解上有诸多偏颇和浅薄的地方;也由于理论功底的薄弱,存有不少逻辑不畅和辞不达意的问题;加之时间紧迫和自己的粗心,与老师的期望相差较远,许多问题还有待于进一步思考和探索,借此答辩机会,万分恳切的希望各位老师能够提出宝贵的意见,多指出这篇论文的错误和不足之处,我将虚心接受,从而进一步深入学习研究,使该设计得到完善和提高。我的介绍完了,谢谢!请各位老师提问。
结束语
结合所学过的知识、透过查阅参考资料初步设计,再交指导老师审查审查透过后,利用xx等完成设计任务及其他资料的编写。最后,我想谈谈这篇论文及自己存在的不足。由于自己学识浅薄,认识潜力不做,对某些问题的理解上有诸多偏颇和浅薄的'地方也由于理论功底的薄弱,存在有不少逻辑不畅和词不达意的地方,许多问题还有待于进一步思考和探讨。借此答辩机会恳切的期望各位老师能够提出宝贵的意见,多指出本设计的错误和不足指出,我讲虚心理解,从而进一步深入学习研究,使该设计得到完善和提高。以上是我的答辩自述,敬请各位评委老师提出宝贵的意见,谢谢!
结束语
最后,我想谈谈这篇论文和系统存在的不足。
这篇论文的写作以及系统开发的过程,也是我越来越认识到自己知识与经验缺乏的过程。虽然,我尽可能地收集材料,竭尽所能运用自己所学的知识进行论文写作和系统开发,但论文还是存在许多不足之处,系统功能并不完备,有待改进。请各位评委老师多批评指正,让我在今后的学习之中学到更多。
谢谢!
在毕业论文答辩过程之中必然涉及到人称使用问题,我建议尽量多地使用第一人称,如“我”“我们”即使论文之中的材料是引用他人的,用“我们引用”了哪儿哪儿的数据或材料,特别是毕业论文大多是称自己作的,所以要更多使用而且是果断地、大胆地使用第一人称“我”和“我们”。如果是这样,会使人有这样的印象:东西是你的,工作做了不少!
我想谈谈这篇论文存在的不足:限于各种条件的制约,使得本论文对如何改善“空巢老人”的生活状况探索不够深入,还需要继续进行思考和探索。
最后,再次感谢X老师在我的毕业论文写作过程之中所给与的悉心帮助与指导;其次我要感谢各位专业老师在这两年来我的教育与培养,使我初步掌握了行政管理专业的基本知识,还要感谢本专业同学对我的关心与支持,和你们生活在一起的日子非常快乐!也非常难忘!
恳请各位老师、同学们进行批评指正。谢谢大家!

毕业论文最后致谢词四
致谢本是我曾经认为最好写的部分,复制粘贴,却迟迟动不了笔。如同四年的大学生涯即将落幕,幕布下的我心里有说不清的遗憾与不舍。这篇本科毕业论文从开题到今天历时九个月,见证了我从保研失利到 考研 成功的惊险与惊喜,其中滋味如人饮水冷暖自知。而这篇论文从最初拿到《结构方程模型的原理与应用》的一头雾水,到如今对

首先,我要真诚的感谢我的论文指导老师李卓卓老师,本次论文从概念提出到确定选题,中间多次的修改到最后的定稿,每一步都在李老师的悉心指导下完成,毫不夸张的说,我们跨越了时差和太平洋。在这漫长的九个月里,李老师对我复习考研给予了最大的理解,不仅给了我复习备考的建议,也给了我宽裕的时间准备,而在我拖延症发作的时候,李老师也及时给了我警醒。正是这位宽严并济的老师,为我论文的完成倾注了大量心血,老师丰富渊博的知识、敏锐的学术思维、精益求精的工作作风和诲人不倦的师者风范让我终身受益,激励着我不断求实进去。

毕业论文最后致谢词五
在论文写作的这一个月来,我其实遇到了很多很多的困难,但是身边一直有老师和同学陪伴我,帮助我,相对你们说一声“谢谢”!
刚开始,由于实习的原因,我的论文进展比较慢,眼看第一次查重就要开始了,我迅速写完了论文,但是却存在大而空的缺点,只能重新写。我有点慌了,时间紧张,又不知道该怎样下手。这时候,我的论文导师程洁老师给了我很大的帮助,她告诉我网络舆论控制只是选题的一个领域,应该从一个更加具体的方面切入,突出在网络舆论控制上的“变化”。根据她的提示,我又在网上搜集了相关的资料,决定通过探讨前后两个案例来展现这种变化。但是由于选择的案例不具有可比性,又被否决了。此时,第一次查重日期已经很近了,我的心里很是焦虑,同组的同学和我一起写论文,她鼓励我调整好心态,再找一找案例,实在没办法可以再向老师求教一下写作思路。我仍然紧张,但是也算是能够稍微平静下来,后来的案例查找慢慢变得顺利起来,论文思路也越理越顺。
在这里,我尤其要感谢程洁老师的敬业和耐心。基本上当天发给程老师的论文她都会在当天尽快回复,即便是深夜发过去的论文,她如果来不及看的话也会告诉你她第二天会看,而且每一个问题、每一个追问她都不厌其烦的指导我。这让作为学生的我感到很有安全感,感觉到自己被重视,自己的论文被认真看待,真的,真的非常感谢程老师这般的敬业!
还有我身边的同学、朋友,他们陪伴我度过了精彩的大学四年,在最后的关头又积极地给予我帮助,从写作思路、查重、论文格式等等方面,我们相互讨论,相互督促对方不断改进和更正。感谢这群小伙伴让我愉快的度过了大学四年。
到这里,我的大学生涯也就此告一段落了,对于母校苏州大学,内心充满了不舍,对于那些谆谆教导我的老师们充满了感激,还有陪我渡过大学四年美好时光的伙伴们,衷心的谢谢你们!
毕业论文最后致谢词六
大学生活一晃而过,回首走过的岁月,心中倍感充实,当我写完这篇毕业论文的时候,有一种如释重负的感觉,感慨良多。
首先诚挚的感谢我的论文指导老师__老师。她在忙碌的教学工作中挤出时间来审查、修改我的论文。还有教过我的所有老师们,你们严谨细致、一丝不苟的作风一直是我工作、学习中的榜样;他们循循善诱的教导和不拘一格的思路给予我无尽的启迪。
感谢四年中陪伴在我身边的同学、朋友,感谢他们为我提出的有益的建议和意见,有了他们的支持、鼓励和帮助,我才能充实的度过了四年的学习生活。
本论文是在导师__教授和__研究员的悉心指导下完成的。导师渊博的专业知识,严谨的治学态度,精益求精的工作作风,诲人不倦的高尚师德,严以律己、宽以待人的崇高风范,朴实无华、平易近人的人格魅力对我影响深远。
不仅使我树立了远大的学术目标、掌握了基本的研究 方法 ,还使我明白了许多待人接物与为人处世的道理。本论文从选题到完成,每一步都是在导师的指导下完成的,倾注了导师大量的心血。在此,谨向导师表示崇高的敬意和衷心的感谢!
本论文的顺利完成,离不开各位老师、同学和朋友的关心和帮助。在此感谢岳保珍高工、张曾教授、李兵云老师、何婉芬老师的指导和帮助;感谢重点实验室的等老师的指导和帮助;感谢福建农林大学谢拥群教授、陈礼辉教授、黄六莲高工的关心、支持和帮助,在此表示深深的感谢。没有他们的帮助和支持是没有办法完成我的博士学位论文的,同窗之间的友谊永远长存。
毕业论文最后致谢词七
金陵的夏总是聒噪的,无论粗壮的法国梧桐上早起的鸣蝉,抑或宿舍区楼下卖炒饭摊子常年旺着的的灶火,更不必提及一张嘴就仿佛已然在吵架的热闹的南京腔。这座城,从未给过我任何江南女子娇小温婉的感觉。可这终究是收获的日子,在感伤毕业离别的同时,必须要留下时间,让心灵沉静下来,回味和 总结 我的四年,我们的四年。
我素来承认自己是一个笨瓜,至少在做学问这件事上,是的。从结构力学到工程结构设计原理,从建筑结构设计到土 木工 程施工,从建筑规范到标准图集,我大学四年的学习,用“举步维艰,如履薄冰”来形容,真的再恰当不过了。也正是如此,考验综合知识运用的完整的毕业设计,着实让我付出了很多心血,也给我的导师李金根先生和身边各位同学带来了许多的麻烦和问题。因此,我首先要表达对我尊重的导师李金根先生和所有我身边帮助过我的老师、学长、同学们的感激。谢谢你们总是很耐心的解答我大大小小的众多问题。对于李金根老师的感激,更因为他一年来对我学习能力的培养、对我严谨思维方式的引导,李老师对完美的孜孜不倦追求的态度,感动了我,也感染了我。追求的态度,学术,亦生活。若我经过四年的沉淀,仍如freshmen样,仅仅将大学的收获定义为知识的吸纳,那我就真成了一个彻头彻尾的笨瓜。象牙塔是这样一个地方,它可能没有教会我所有的知识,却教会了我如何用工学特有的严谨思考问题,教会我工程人豁达的生活哲学,教会了我追求自己的追求,教会了我宽容和尊重。所谓人才,即“人”与“才”的集大成者,无“人”,亦无“才”可谈。因此在这里,我要表达一份对最初天性的感激——感激我的父亲___先生,母亲___女士,谢谢你们赐予我最宝贵的四份礼物:珍贵的生命、接受早期教育的机会、从小教育我如何做一个正直热血之人,并且一直支持我的学业和生活;我还要感谢我的干爸___先生、___先生,干妈___女士、___女士,谢谢你们四年来对我视如己出的关心、照料、帮助和教导,谢谢你们教会了我更为乐观、豁达的面对生活,谢谢你们教会了我怀揣感激;我更要感谢另一位我最喜欢的老师——单建先生和夫人黄女士,能与单建老师和黄阿姨坐在一起探讨诗歌、分享人生的阅历,是我大学生活重要的组成部分。
当然,我还要感激生命。汶川地震的发生,让我更加珍视我的生命,和我拥有的一切。在慨叹“活着真好”的同时,我无法回避的开始重新思考生活的意义、求知的意义,和作为一名土建工程师的责任。希望我的学识和努力,可以在未来的日子中带给社会一些有益的贡献,可以让我的祖国更加强大更加美好。
闭上眼,我感觉自己仿若置身百年东大蓝汪汪的喷水池前,在树荫的遮蔽下,一步步的向校门迈进。脑中的校门胜似天安门广场的雄伟、庄严,脑中的自己如即将踏上征途的战士般沉重、不舍。转过身,回望远处蓝穹顶的大礼堂,东南大学的浑然气魄尽收眼底。这回眸,宛若我的毕业设计,我的思考,和我的致辞。
故此,我称这份毕业设计为,一次深刻的转身,一次华丽的工程思考。

毕业论文最后致谢词十
时光的流逝也许是客观的,然而流逝的快慢却纯是一种主观的感受。当自己终于可以从考研、找工作、毕业论文的压力下解脱出来,长长地吁出一口气时,我忽然间才意识到,原来四年已经过去,到了该告别的时候了。一念至此,竟有些恍惚,所谓白驹过隙、百代过客云云,想来便是这般惆怅了。
可是怅然之后,总要说些什么。大学四年,生活其实很简单,只是一些读书、写字和考试的周而复始。如果把这种单调的生活看作一场场循环的演出,那么我只是一个安静的演员。这篇毕业论文也称不上什么精彩的台词,只不过是这种循环演出即将告一段落时的谢幕词。但是无论多么蹩脚的演员,无论台下有多少观众,即使是只说给自己听,在他谢幕时也总要感激一些人,是这些人帮助他走上舞台,成功或者不那么成功地演出。
我在这里首先要感谢的是我的学位论文指导老师张杰/刘淑芹老师。这篇毕业论文从开题、资料查找、修改到最后定稿,如果没有她的心血,尚不知以何等糟糕的面目出现。我很自豪有这样一位老师,她值得我感激和尊敬。
感谢和我共度四年美好大学生活的20__级工商管理与法学双学位班的全体同学。感谢管理学院和法学院的所有授课老师,你们使我终身受益。感谢所有关心、鼓励、支持我的家人、亲戚和朋友。

0 前年,如果轿车安装有 ABS(防抱死制动系统),不但说明该车的安全性能出类拔萃,而且档次也相当高级。今天,安装ABS的轿车已经相当普遍,经济型车也安装有ABS。防抱死制动系统 ABS(Anti-lock Braking System)属于汽车的主动安全系。ABS系统的配置,既可有效避免紧急制动时车轮抱死(打滑)现象的发生,同时还可以保持车辆制动过程中的平稳。 随着对汽车安全性能的要求越来越高,一些中、高档级的轿车已经不满足于ABS,还安装了ASR(驱动防滑系统,Acceleration Slip Regulation,又称牵引力控制系统)防止车辆尤其是大马力车在起步、再加速时驱动轮打滑现象,以维持车辆行驶方向的稳定性。ASR与ABS的区别在于,ABS是防止车轮在制动时被抱死而产生侧滑,而ASR则是防止汽车在加速时因驱动轮打滑而产生的侧滑,ASR是在ABS的基础上的扩充,两者相辅相成.或者 ESP(电控行驶平稳系统),使汽车的安全性能进一步提高。ASR的作用是当汽车加速时将滑动率控制在一定的范围内,从而防止驱动轮快速滑动。它的功能一是提高牵引力;二是保持汽车的行驶稳定。行驶在易滑的路面上,没有 ASR 的汽车加速时驱动轮容易打滑; 如是后驱动的车辆容易甩尾, 如是前驱动的车辆容易方向失 控。有 ASR 时,汽车在加速时就不会有或能够减轻这种现象。在转弯时,如果发生驱动轮 打滑会导致整个车辆向一侧偏移,当有 ASR 时就会使车辆沿着正确的路线转向。 汽车的牵引力控制可以通过减少节气门开度来降低发动机功率或者由制动器控制车轮 打滑来达到目的,装有 ASR 的汽车综合这两种方法来工作,也就是 ABS/ASR 形式。 装有 ASR 的车上,从油门踏板到汽油机节气门(柴油机喷油泵操纵杆)之间的机械连 接被电控油门装置所取替。 当传感器将油门踏板的位置及轮速信号送至控制单元 (CPU) 时, 控制单元就会产生控制电压信号, 伺服电机依此信号重新调整节气门的位置 (或者柴油机操 纵杆的位置) ,然后将该位置信号反馈至控制单元,以便及时调整制动器。 ESP(电控行驶平稳系统,英文全称 Electronic Stabilty Program)包含 ABS 及 ASR,是 这两种系统功能上的延伸。因此,ESP 称得上是当前汽车防滑装置的最高级形式。ESP 系统 由控制单元及转向传感器(监测方向盘的转向角度) 、车轮传感器(监测各个车轮的速度转 动) 、侧滑传感器(监测车体绕垂直轴线转动的状态) 、横向加速度传感器(监测汽车转弯时 的离心力)等组成。 控制单元通过这些传感器的信号对车辆的运行状态进行判断,进而发出控制指令。有 ESP 与只有 ABS 及 ASR 的汽车,它们之间的差别在于 ABS 及 ASR 只能被动地作出反应, 而 ESP 则能够探测和分析车况并纠正驾驶的错误,防患于未然。 ESP 对过度转向或不足转向特别敏感,例如汽车在路滑时左拐过度转向(转弯太急)时 会产生向右侧甩尾, 传感器感觉到滑动就会迅速制动右前轮使其恢复附着力, 产生一种相反 的转矩而使汽车 保持在原来的车道上。当然,任何事物都有一个度的范围,如果驾车者盲 目开快车,现在的任何安全装置都难以保证其安全。据汽车工程界专家介绍,将来 ASR 等将变得如同 ABS 一样普及,因为 ABS、ASR 及 ESP 包含着技术及性能上的贯通。有专家认为在一定的范围内 ASR 等装置有取替 4 轮驱动的可能。例如轿车,过去人们认为提高轿车行驶性能最好是采用 4 轮驱动,可是与 4 轮驱动 相比,ASR 等装置更适合轿车。这是因为 4 轮驱动结构复杂成本高,增加车重而且耗油, 而 ASR 等装置结构简单安装方便,在一般城镇道路上使用效果并不差。 ABS/ASR/VDC 系统 ABS/ASR 系统成功地解决了汽车在制动和驱动时的方向稳定性问题,但不能解 决汽车转向行驶时的方向稳定性问题。 例如当汽车转向行驶时, 不可避免地受到侧向和纵向 力的作用,只有当地面能够提供充分的侧向和纵向力时,驾驶员才能控制住车辆。如果地面 侧向附着能力比较低,就会损害汽车按预定方向行驶的能力。雨天汽车高速转向行驶时,常 常侧向滑出,就是地面侧向附着能力不足的缘故。为解决此问题,最近汽车工业发达国家又 在 ABS/ASR 系统的基础上发展成汽车动态控制系统(英文名称为 Vehicle Dynamics Control,简称 VDC)。这个系统把汽车的制动、驱动、悬架、转向、发动机等各主要总成的控制系统在功能上、 结构上有机的综合在一起,可使汽车在各种恶劣工况下, 如冰雪路面上、 对开路面上、弯道路面上以及采取规避动作移线、制动、加速和下坡等工况行驶时,对不同承载、 不同轮胎气压和不同程度的轮胎磨损都有良好的方向稳定性,表现出最佳的行驶性能。 VDC 的应用,在制动、加速和转向方面完全解脱对驾驶员的高要求,在汽车的主动安全行驶方面竖立了一个新的里程碑。VDC 系统对转向行驶的控制主要是借助于对各个车轮的制动控制和发动机功率输出控 制来实现的。例如汽车左转弯时,若前轮因转向能力不足而趋于滑出弯道,VDC 系统即可 测知侧滑即将发生,就采取适当制动左后轮的办法。左后轮产生的制动力可帮助汽车转向, 使汽车继续按照理想的路线行驶。若在同一弯道上,因后轮趋于侧向滑出 而转向过多,VDC 系统即采取适当制动右前轮的办法,维持车辆的稳定行驶。在极端情况 下,VDC 系统还可采取降低发动机功率输出的办法降低行驶车速,减少对地面侧向附着能 力的需求来维持车辆的稳定行驶。采用 VDC 系统后,汽车在对开路面上或弯道路面上的制 动距离还可进一步缩短。VDC 系统主要应用了下述传感器:车轮转速传感器,用来跟踪每一车轮的运动状态; 方向盘转角传感器,用来传感方向盘的转角; 横摆角速度传感器,用来记录汽车绕垂直轴线转动的所有运动; 侧向加速度传感器,用来检测转向行驶时离心力的大小; 车轮位移传感器,用来测量车轮和车身相对位置的变化。 这些传感器的核心部分是横摆角速度传感器, 这是因为汽车的横摆角速度和方向盘 转角的比值是反应汽车转向行驶品质的一个重要参数。位移传感器的信号传给电子控制装置,用来控制半主动悬架,改善汽车的接地性能。其它传感器则把汽车每一瞬时的运动状态 的信息传给电子控制装置,使之与理想的运动状态相比较,一旦汽车偏离了理想的路线,它就会在极短的时间内采取纠正措施, 给制动控制系统或发动机控制系统发出相应的指令, 维持汽车在理想的路线上行驶电子制动力分配系统(EBD) EBD 能够根据由于汽车制动时产生轴荷转移的不同,而自动调节前、后轴的制动 力分配比例,提高制动效能,并配合 ABS 提高制动稳定性。汽车在制动时,四只轮胎附着 的地面条件往往不一样。比如,有时左前轮和右后轮附着在干燥的水泥地面上,而右前轮和 左后轮却附着在水中或泥水中, 这种情况会导致在汽车制动时四只轮子与地面的摩擦力不一 样,制动时容易造成打滑、倾斜和车辆侧翻事故。EBD 用高速计算机在汽车制动的瞬间, 分别对四只轮胎附着的不同地面进行感应、计算,得出不同的摩擦力数值,使四只轮胎的制 动装置根据不同的情况用不同的方式和力量制动, 并在运动中不断高速调整, 从而保证车辆 的平稳、安全。 安全气囊(SRS) 安全气囊是现代轿车上引人注目的高技术装置。安装了安全气囊装置的轿车方向 盘,平常与普通方向盘没有什么区别,但一旦车前端发生了强烈的碰撞,安全气囊就会瞬间 从方向盘内“蹦”出来,垫在方向盘与驾驶者之间,防止驾驶者的头部和胸部撞击到方向盘 或仪表板等硬物上。安全气囊面世以来,已经挽救了许多人的性命。研究表明,有气囊装置的轿车发生正面撞车,驾驶者的死亡率,大轿车降低了 30%,中型轿车降低 11%,小型轿 车降低 14%。安全气囊主要由传感器、微处理器、气体发生器和气囊等部件组成。传感器和微处理器用以判断撞车程度,传递及发送信号;气体发生器根据信号指示产生点火动作,点燃固态燃料并产生气体向气囊充气,使气囊迅速膨胀,气囊容量约在(50-90)L。同时气囊设有安全阀,当充气过量或囊内压力超过一定值时会自动泄放部分气体, 避免将乘客挤压受伤。安全气囊所用的气体多是氮气或一氧化碳。 除了驾驶员侧有安全气囊外,有些轿车前排也安装了乘客用的安全气囊(即双安全气囊规格),乘客用的与驾车者用的相似,只是气囊的体积要大些,所需的气体也多一些而已。另外,有些轿车还在座位侧面靠门一侧安装了侧面安全气囊。
随着汽车行业技术的不断发展,汽车发动机技术也在不断的提高。下面是我为大家精心推荐的汽车发动机技术论文 范文 ,希望能对大家有所帮助。汽车发动机技术论文范文篇一:《试谈汽车发动机的可变气门技术》 摘要:汽车发动机可变气门技术是当今汽车发动机普遍配置的设备系统。该系统可以对发动机凸轮的相位或者气门的升程进行有效的调节,从而使汽车发动机的配气过程得到优化。因为汽车发动机在高转速和低转速状态下,气门的正时角对发动机的经济性以及动力有所影响,从而提高进气量以及扫气效率,如今的汽车发动机普遍应用这项技术。 关键词:汽车发动机;可变气门技术;气门正时技术;气门升程技术;配气过程 在汽车发动机的运行过程中,如果发动机在运行过程中,随着发动机气门数量的增多和发动机转速的提高,气门正时和气门升程不能随之改变,那么当汽车发动机处于转速过低、转速过高或者功率输出的状况下,就很难保证燃油的消耗问题。如果汽车发动机使用的是单个气门,在对燃油供给方进行控制时,对这个问题解决起来就会很难。但是如果换一种方式,如使用“可变性能”对其进行“综合处理”,那么这样的问题就很容易被解决。 1 气门正时技术 气门正时也就是汽车发动机在运转过程中气门打开的时间。其功能是活塞运动到一定位置时,对气门的开启和关闭时间进行控制。一般情况下,发动机进气门的活塞运动程序应当从下向上,当气门开始排气时,气门打开;当活塞到达气门的上止点时,一个排气运动周期完成,气门关闭。这个过程中,因为运动的空气存在惯性,因此需要一定的时间进行反应。进行排气的过程中,为了让更多的空气进入气缸,更多的废气排出气缸,就要在活塞到达之前打开,并且在活塞运动到下止点之下关闭;发动机的排气门运用同样的原理,排气门应该在活塞开始向下运动之前打开,在活塞运动到下止点之后再关闭。在活塞运动的过程中,排气门和进气门可能会在一定的时间范围内同时打开,这叫做气门叠加,在气门叠加现象产生时,曲轴会产生一定角度的转动,这个角度是气门叠加角,图1是汽车发动机气门配气相关结构图。 发动机的转速处于不同状态时,对于气门叠加角的要求也有所不同,在发动机低转速时,其气门叠加角就越小,发送机转速高,所产生的气门叠加角就会越大。如汽车发动机没有运用气门正时技术,这两个要求就很难同时得到满足,传统的汽车发动机工作原理主要是:当汽车发动机处于低速转动状态时,其中凸轮的转速也非常慢,因此气门的进气速度也随之减慢,当气门打开时,需要的时间较长,但是气门的开度很小。如果汽车行驶的速度达到120km/h时,发动机的转速一般为3000~4000rpm,有可能会达到更高水平,此时汽车发动机气门的开启和关闭速度加快,气缸空气进入的速度开始加快,在这一运动过程中,虽然其进气量很大,但是发动机气门的开启时间非常短,这会在一定程度上降低氧气含量,导致燃油燃烧所需氧气不足,从而使燃油燃烧不够充分。因此可以在这样的发动机上引入可变气门技术,这一技术可以有效解决以上提到的问题,从而大大改善发动机的燃油效率。在运行过程中,对凸轮进行改造,并且对相关的传感信号进行充分收集,汽车发动机如果处于转速非常低的情况下,这时发动机中正时技术就可以对其进行很好的控制;当汽车发动机处于高速运转状态时,可以对气门的开度进行较为科学的调整。 2 气门升程技术 气门升程技术指的是对气门开启的开度大小进行控制的技术。当发动机在运行过程中,气门行程较远的情况下,所进气截面的面积就会随之增大,因此对进气产生的阻力会降低,从而使得气缸的进气更加通畅,这样的运行状态比较适合汽车在高速行驶的状态下。如果在汽车行驶速度较慢的情况下,就会导致进气时达不到要求的负压,从而导致汽车处于低速形式的状态下时,产生运转无力或者不够平稳的现象。如果气门很小,汽车发动机在慢速运转过程中,所需的负压会得到满足,保证氧气的充足和燃油的充分燃烧。然而当汽车处于高速行驶的状况下时,空气的流速就会加快,气阻也会增大,这些情况的出现就会导致气门在进气和排气的过程不够畅通。在汽车发动机中运用可变气门技术,就可以对这两方面的问题进行权衡。气门正时技术只能够对汽车发送机中气门开启的时间进行控制,对于气门开启的开度无法控制。因此要在汽车发动机中运用可变气门的升程技术,这样才能进一步提高汽燃油的燃耗效率,提高汽车经济性能。 3 典型的可变气门升程技术控制为主的发动机技术 本田汽车中的“VTEC”系统应用 “VTEC”可以同时对发动机气门开度和气门开启时间进行控制的系统,对“VTEC”进行控制的系统主要是“ECU”,它通过发动机中各个传感器,其中包括气缸进气压力传感器、发动机转速传感器、车辆行驶速度传感器、水温传感器等,根据其产生的信号,进行相应指令的发送,同时可以控制凸轮在特定的范围内运转,以此对气门的开闭时间和开闭开度进行合理控制。一般的汽车发动机中,每个汽缸只配备一个凸轮对其进行驱动,但是本田汽车中VTEC系统发动机内含有两个凸轮对其进行驱动,即中低速、高度运转两个组合,通过对电子系统的运用,使其自行进行操纵,从而达成自动转换目标。本田汽车发动机中利用的VTEC系统,可以同时对发动机的低速运转和高速运转中气门的开闭进行时间和开度的控制,这样就能同时达成汽车的动力性和经济性。 本田“VTEC”与其他汽车发动机不同的地方主要是凸轮和摇臂的数目和控制 方法 。其是世界上第一个能够对气门的开闭时间以及升程两个性能同时控制的气门控制系统。其系统通过计算机对气门的正时和升程进行控制,可以在很大程度上提高汽车燃油效率,本田公司几乎在所有车档中均运用了“VTEC”系统。 丰田汽车VVT-i智能可变气门系统 VVT-i系统是丰田汽车中发动机可变气门系统,当前这项技术已经在丰田汽车中普遍使用。VVT-i系统可以对发动机气门运动进行连续的正时调节,但是对气门的开度大小不能控制。这项技术的工作原理主要是:当汽车的运行速度由低到高运行时,“ECU”就会向凸轮控制下小涡轮内挤压机油,从而使小涡轮进行运转,其运转是相对凸轮进行的,这样就使得凸轮在60。范围内前后旋转,这样就会对气门的开启和闭合时间有所控制,从而实现气门的连续这时目标。这项技术的最大特点是,可以根据汽车发动机所处状态对凸轮进行合理控制,对凸轮轴的转角进行合理的调整,从而优化配气时机,保证对燃油的配气达到最佳状态,以此来帮助燃油充分燃烧,并且提高汽车扭矩,提升汽车的各项性能。 4 结语 在汽车发动机可变气门技术中,升程系统主要控制气门的开度,而正时系统是控制气门开闭的时间。它们均决定了发动机进气量的大小,同属于汽车发送机可变气门控制系统。如今可变气门技术发展得越来越快,这项技术在汽车发动机中的使用可以说是汽车领域发展的一个里程碑,可以看出未来的汽车技术将向着越来越先进的方向发展。 参考文献 [1] 邓明阳,孙旭.发动机全可变气门升程技术现状的分析与展望[J].南通航运职业技术学院学报,2011,(3).

(1)减小进气系统的流动损失。①减小进气门处的流动损失。可通过增大进气门的直径,选择合适的排气门直径;增加气门的数目,采用小气门;改善进气门处流体动力学性能,减小气门处流动损失;采用S(活塞形成)/D(缸径)值较小的发动机等措施可以减小进气门处的流动损失。②减小整个进气管道的流动阻力。进气道应该有足够的流通截面积、表面光滑、拐弯小、多段通道连接要对中;进气管应该有足够的流通截面积、表面光洁,避免急转弯和流通截面的突然变化;空气滤清器的阻力应随结构和使用时间的延长而不同。(2)减少对新鲜充气量的加热。凡是能降低活塞、气门等热区零件的温度和减小接触面积的措施都是有利于减小对新鲜充气量的加热。(3)减小排气系统的阻力。减少排气系统中排气门座、排气道、排气管、排气消声器的阻力,对降低排气压力、减小排气损失均有利。(4)合理选择配气相位。配气相位是否合理主要根据以下几个方面来判断。①充气效率高,保证发动机的动力性能,主要由进气门迟闭角决定。②必要的燃烧室扫气,以保证降低高温零件的热负荷,使发动机运行可靠,主要由进气门迟闭角决定。③合理的排气温度,主要由排气提前角决定。④较小的换气损失、以保证发动机的经济性,主要由进排气门重叠角决定。 2 减小机械损失可从几个方面着手 (1)降低活塞、活塞环、连杆等往复运动机件的摩擦和质量。(2)降低滑动部件的滑动速度。(3)减少润滑油的搅拌阻力。(4)改良润滑油,使其低粘度化。(5)合理选择摩擦零件的材料。 二、发动机节能的措施 1 发动机稀燃技术 也叫发动机稀薄燃烧技术,指采用发动机的实际空燃比远大于理论空燃比的情况下进行的具有良好动力性、经济性和排放行的燃烧技术。 实现的技术途径:(1)实现稀燃混合气。实现稀燃混合气的措施有:使汽油充分雾化;采用结构紧凑的燃烧室;加快燃烧速度;提高点火能量;采用分层燃烧技术。(2)采用分层燃烧系统。主要有气道喷射稀燃系统和直接喷射稀燃系统。 2 发动机的增压技术 对进入气缸的空气提前进行压缩,使单位时间进入燃烧室的新鲜空气量增多,增加发动机的充气效率,提高发动机的功率。 3 燃油掺水节油技术 发动机采用掺水形成的乳化燃油,可以减少排气中的氮氧化合物等有毒成分、降低烟度减少污染,还能有效降低油耗,节约能源。 4 发动机可变气缸排量技术 发动机在中低负荷情况下,使部分气缸停止工作,增加工作气缸的负荷率,使其工作点落入低燃油消耗率和低排放工作区域内,从而改善车辆的经济性和排放性能;当发动机需要大功率时,则让全部气缸工作,体现发动机的动力性。 5 发动机可变配气正时技术 根据发动机转速和负荷的变化,适时调整配气相位和气门升程。 6 可变进气歧管技术 ECU根据发动机转速和负荷的变化而改变进气道的长度,在高转速时使进气通道变短,减少进气流动损失,提高发动机的高速功率。在低转速和低负荷及起动情况使进气通道变长,管内空气流动的动能增加,导致进气流速加快,充气效率提高,在同样的燃烧条件下会获得更大的输出功率,增加转矩。 可变进气歧管技术主要包括可变进气歧管长度和可变进气共振技术.。 7 可变压缩比技术 采用可变压缩比技术对于自然吸气发动机,在部分负荷情况下压缩比可以设计高一些;对于增压发动机在增压压力比较低的低负荷情况下,适当降低压缩比,使压缩比随发动机负荷的变化连续调节,这样可以避免爆燃,又提高了在高压缩比情况下中低负荷的工作效率,增加了动力性能,提高了济性,保证了发动机工作效率的最大化。 改变发动机压缩比的方法有改变燃烧室的容积和改变活塞行程。 8 汽油机燃油喷射与点火系统的电子控制技术 在汽油机电控燃油喷射系统中,电控单元主要根据进气量确定基本的喷油量,再根据其他传感器信号对喷油量进行修正,使发动机在各种工况下均能获得最佳浓度的混合气,从而提高发动机的动力性、经济性和排放性;汽油机电控点火系统(ESA)根据相关传感器信号,判断发动机的运行工况和运行条件,选择最佳的点火提前角点燃可燃混合气,从而改变发动机的燃烧过程,实现发动机动力性、经济性和排放性的提高。 9 柴油机燃油喷射系统的电子控制技术 在柴油机电控燃油喷射系统中,ECU主要根据发动机转速和负荷信号来确定基本供油量和供油正时,再根据其他传感器信号进行修正。 10 电子节气门技术 汽车电子节气门技术(ETC)淘汰了传统加速踏板采用拉索或杠杆机构,与发动机节气门之间进行直接的机械连接,通过增加相应的传感器和电控单元,实现精确控制节气门的开度。该技术可以实现发动机转矩和空燃比的精确控制,有助于提高汽车行驶的动力性、平稳性、经济性以及降低排放污染。 11 陶瓷发动机 为了减小发动机能量损失中占绝大部分的冷却损失和排气损失,一般采用取消或部分取消冷却系统的方法,并使用陶瓷等耐高温、耐磨损、耐腐蚀、重量轻和强度高等特点的隔热材料或其他方法减少燃烧室内热量的散失,使发动机在更高的工质温度下工作;利用排气能量。 12 EccoBoost 发动机技术 一种兼具涡轮增压技术和燃油直喷两种技术于一体的发动机技术,发动机能获得更高的动力性和经济性。 结语 根据中国的能源政策和汽车工业发展情况来看,国家首先应该大力发展柴油机技术,主要是研究电控柴油机;其次大力发展电动汽车,优先发展混合动力汽车,加大电池续航能力的研究;再次大力研发推广代用燃料车。发动机油耗的高低直接反应了我国发动机设计与制造水平,汽车发动机节能技术的推广应用,将大力推动我国汽车工业的发展。 参考文献 [1]许文靖.现代汽车节能技术探析[J],科技创新导报,2009(24). 汽车发动机技术论文范文篇三:《浅谈汽车发动机维修技术》 【摘 要】: 作为汽车的心脏部位,发动机在汽车的正常运行和操作中其中至关重要的作用。因此,平时需要加强对发动机的维修和保养。而针对汽车发电机的维修,其需要比较全面的技术知识和实践操作能力。因此,汽车发动机的维修可以说是一个需要技巧和技术的硬活。本文从汽车发动机检查以及汽车发动机的诊断和维修两个方面出发,具体阐述其相关的维修技术,希望对学习汽车发动机维修的人员有所帮助。 【关键词】: 汽车;发动机;维修;技术 1 传统的发动机维修工艺 发动机的内部零部件的检查: 由于汽车发动机内部的曲轴和活塞往往是比较容易出故障的地方,如汽车突然无法启动等,很可能是因为汽车发动机内部活塞不能运作造成的。因此当汽车发动机出现故障需要维修的情况下,可以先对其曲轴和活塞进行检查,其具体步骤如下: 曲轴的检查 对于曲轴容易出现的故障,主要有轴颈处容易磨损,容易出现扭曲变形或者疲劳裂纹,因此需要进行重点检查。1)裂纹的检查:对于曲轴裂纹的检查,其相应的检查方法有超声波探伤检查,浸油敲击法检查,磁力探伤检测仪进行检查和X光探伤检查。在用浸油敲击法对曲轴进行检查时,需要先将曲轴在煤油中浸泡一段时间, 然后再将曲轴从煤油中取出来,擦干净后在曲轴上撒一些白粉,再对曲轴的不同部位进行轻敲,如有出现了比较明显的油迹,这说明曲轴的这个部位有裂纹。对于磁力探伤仪检查,其磁力线会穿透曲轴被检查的部分,如果在该部分有裂纹的话,那么这个地方的磁力线就会出现偏散,然后将磁力粉撒在该部位,从会显示出裂纹的具体大小和具体位置;2)弯曲变形的检查:针对曲轴弯曲变形的检查,可以先将整个曲轴的两个顶端用V型版块支承住,如图1所示,然后用在主轴中间用百分表的触头抵着。当曲轴转动一周后,在指针上对出角度的最小值和最大值,并且计算两者之差,这个差值就是曲轴弯曲变形的差值了,如果其值大于, 那么曲轴弯曲的比较严重了,为了确保发动机的正常运行,需要及时更换曲轴。 活塞连杆组的检查。 对应活塞部位的检查,主要是检查其活塞销座的尺寸和裙部直径等是否发生了变化,或者是否在使用过程中发生了堵塞等。其主要的检查方法一般有两种,第一种检查方法是用千分尺进行测量,通过测量裙部直径的大小和活塞汽缸磨损部位值的大小,将这两个测得的数据相减,然后和配缸间隙值进行比较,如果差值大于, 则说明活塞磨损比较严重,不能够再使用啦。另一种方法是塞尺进行测量,通过测量配缸间隙来判断其汽车发动机内部活塞是否可以正常使用。首先将塞尺放入安装气环的环槽内,然后以35N的拉力轻轻转动塞尺,当感到轻微的阻力时停止转动,这样就可以用塞尺测量活塞裙部和活塞侧隙差值的大小,当活塞受到磨损越多时,其相应的差值也越大,当该值超过时,这该活塞不能再使用啦,需要为汽车发动机配备新的活塞。 2 汽车发电机的诊断和维修 发动机失速故障 发动机如果出现了失速故障,其一般表现为发动机转速一会低一会高的情况,而这种情况就是常见的发动机失速故障了。出现这种故障的原因主要是因为点火控制系统出现故障,或燃油喷盘系统出现问题,又或者是整个发动机的进气系统出现了问题等。例如,出现了燃油喷盘系统的故障,很有可能是系统线路接触不稳,油管变形或者燃油滤清器灰层太多等。针对不同的原因,可以采取不同的措施进行维修。 其相关的故障排除和维修的方法如下:1)如果是喷油系统出现问题,检查是否是线路接触不良,如果是,则可以调整线路或更换导线的方法进行维修,如果是 机油滤清器盖等太多灰层了,则可以采用清洁滤清器盖的方法进行修复;2)如果是进气管出现了问题,则仔细检查是否有各软管或者其相接的地方出现了漏气,也可以检查PVC阀管子等是否通气正常,如果不是,则可以考虑修复或替换相应的管子;3)针对点火控制系统出现的问题,则需要检查各缸火花塞是否正常工作了。例如,火花塞积累的灰层太多,引起发动机转速不正常,则可以通过彻底清洁火花塞来进行维修。 发动机怠速不良故障 发动机怠速不良故障的现象主要是发动机怠速不稳,停车易熄火。在故障诊断方面,可以先检测发动机燃油压力。将燃油压力表连接到油压检测孔上,起动发动机,油压表指示正常,压力为265kPa,拨掉油压调节器真空管,油压上升到340kPa。上述结果均在标准范围内,说明燃油管路系统无故障。然后再检查气缸压力。预热发动机,温度到85℃,打开节气门,用缸压表测量各缸压力,当压力值均为l1OOkPa左右,各缸压差小干300kPa时,上述情况表明发动机气缸密封性出现了问题。 针对该故障的维修,其方法如下:清洗怠速电动机、节气门体。将怠速电动机、节气门体拆下,彻底清洗各空气通道,并用压缩空气吹净。用万用表测量一下怠速电动机电阻值,电阻为20Ω,在18~24Ω正常范围内。测量节气门位置传感器,输出阻值呈线性变化,且在正常范围内。若发现进气总管内沉积有异物,用缠有麻布的铁线将其清理干净。为彻底根除故障,还可以对喷油器进行清洗、检测。 自诊断系统可能出现以下几种情况:汽车运行时故障明显,传感器有故障而自诊断系统没有监测到。一是电控汽车控制电脑(ECU)对传感器信号进行检测时,只能接受其设定范围之内的传感器非正常信号,从而判断传感器的好与坏,记录或不记录故障代码。一旦解读故障代码故障后,只要对相应的传感器、导线连接器、导线进行检查,找到并排除短路、断路的故障即可。但是,若因某种原因致使传感器灵敏度下降、反应迟钝、输出特性偏移等,则自诊断系统就测不出来了。这时就应该依据发动机的故障征兆进行分析判断,继而传感器单体进行针对性检测,以便找到并排除传感器故障。二是由于发动机工况故障现象相似,ECU监测失误,自诊断系统可能显示错误的故障代码。例如,对于装有三元催化转化器的电控汽车,一旦使用过含铅汽油,这类故障特性有时较为明显。在汽车进行检修时,经常会发现故障代码显示的是“水温传感器断路或短路”故障,而发动机故障症状却是:无论发动机在冷车状态下或者热车状态下都不好起动,并且拌有怠速不稳和回火现象,发动机的转速绐终提不高。显然这些故障与水温传感器的关系并不十分密切,在对水温传感器进行单体测量后并未发现任何故障。 但是,当从汽车上拆下三元催化转换器并剖开后发现,三元催化转换器内部严重堵塞,因此可以断定发动机故障是由此而引起。因此当自诊断系统出现故障代码以后,还应该与发动机的实际故障症状进行分析比较,以得到正确合理的判断,不应该将故障代码当作排除故障的唯一依据。三是电控汽车使用维修不当也可能引发错误的故障代码。在对电控汽车实施维修时,由于维修人员系统输出错误的故障办法。例如,在发动机运转过程中,随意或者无意把传感器插接头拔下,每拔下一次传感器插接头,自诊断系统就会记录一次故障代码。另外,若在上一次汽车维修时,由于操作不当而未能完全清除掉旧的故障代码,那么电脑也同样将原来的旧故障代码保存其内,因此在对电控汽车维修时也要加以注意,不应造成不必要的人为故障代码。 利用常规的检查方法如“五油、三液、一媒,的检查不可忽视,即对透平油、机油、自动变速器油、转向助力油、齿轮油、制动液、冷却液,刮水清洗液以及冷媒的检查。绝大部分高级轿车上仪表灯全部用英文显示,如wash fluid灯亮,应检查清洗液和储存器内液面,添加后即可消除该警报灯亮。一辆奥迪轿车ABS灯点亮,似乎是一个大的故障,车主急忙赶往奥迪A6维修中心检修,经检查发现就是制动液容器内的液体低于警戒线,补充完制动液后故障排徐,解决起来很简单。 通过车用零件液体的品质,来判断故障。一辆广州本田车雅阁7230轿车的自动变速器油液变紫,而且有少量的混蚀物,此时行车中动力不足,起速过慢。因此,根据油液的颜色可断定故障的原因是自动变速器的故障而不是发动机动力不足,拆油底壳,检查证明判断是正确的。 检查线路也一样重要。一辆雪铁龙轿车左前轮不升也不降,而其他三轮传动正常。检查发现该车左前空气弹簧减振器排气阀线斯开,接通线路后左前轮活动恢复正常。应该仔细看而不是走马观花的浏览,这样才能达到事半功倍的效果。 通过对油液的“闻”可知油液的品质及该系统基本的工作情况,通过对发动机的排放气体的闻,可以感觉发动机的工作情况,从而为故障判断提供指导。如一辆桑塔纳2000GSi轿车,急加速抖动严重。通过对排放气体气味的分析,认为是高压线有时断火,更换后,故障排除“闻”在维修中比其他手段用得相对较少,但并不是说它不重要,运用恰当在故障判断上可以让我们少走许多弯路。 虽然汽车发展机电一体化越来越多,汽车维修更多是靠专用的故障诊断仪器,但一些特殊故障仍然需要 经验 丰富的维修技术人员靠传统维修手段来判断故障,未来的汽车维修人员不仅仅需有外语基础,电脑常识等高科技知识,同时也应具备丰富的传统维修技术。 3 结论 从上面的分析可以看出,本文只是简单的介绍了汽车发动机比较常见的故障以及出现故障的原因和解决的方法。其实,整个汽车发动机的维修覆盖面比较广,其相应的维修技术也比较全面复杂,要熟练的掌握汽车发动机的维修技巧和相关技术,还需要学习和实践很多知识,比如电控燃油系统的检查和维修等,本文就不在此一一赘述。 参考文献:

汽车维修新技术论文篇二 汽车发动机的维修技术分析 摘 要 作为汽车的心脏部位,发动机在汽车的正常运行和操作中其中至关重要的作用。因此,平时需要加强对发动机的维修和保养。而针对汽车发电机的维修,其需要比较全面的技术知识和实践操作能力。因此,汽车发动机的维修可以说是一个需要技巧和技术的硬活。本文从汽车发动机检查以及汽车发动机的诊断和维修两个方面出发,具体阐述其相关的维修技术,希望对学习汽车发动机维修的人员有所帮助。 关键词 汽车;发动机;维修;技术 中图分类号 U46 文献标识码A 文章 编号 1674-6708(2014)114-0109-02 1 传统的发动机维修工艺 发动机的内部零部件的检查: 由于汽车发动机内部的曲轴和活塞往往是比较容易出故障的地方,如汽车突然无法启动等,很可能是因为汽车发动机内部活塞不能运作造成的。因此当汽车发动机出现故障需要维修的情况下,可以先对其曲轴和活塞进行检查,其具体步骤如下: 曲轴的检查 对于曲轴容易出现的故障,主要有轴颈处容易磨损,容易出现扭曲变形或者疲劳裂纹,因此需要进行重点检查。1)裂纹的检查:对于曲轴裂纹的检查,其相应的检查 方法 有超声波探伤检查,浸油敲击法检查,磁力探伤检测仪进行检查和X光探伤检查。在用浸油敲击法对曲轴进行检查时,需要先将曲轴在煤油中浸泡一段时间, 然后再将曲轴从煤油中取出来,擦干净后在曲轴上撒一些白粉,再对曲轴的不同部位进行轻敲,如有出现了比较明显的油迹,这说明曲轴的这个部位有裂纹。对于磁力探伤仪检查,其磁力线会穿透曲轴被检查的部分,如果在该部分有裂纹的话,那么这个地方的磁力线就会出现偏散,然后将磁力粉撒在该部位,从会显示出裂纹的具体大小和具体位置;2)弯曲变形的检查:针对曲轴弯曲变形的检查,可以先将整个曲轴的两个顶端用V型版块支承住,如图1所示,然后用在主轴中间用百分表的触头抵着。当曲轴转动一周后,在指针上对出角度的最小值和最大值,并且计算两者之差,这个差值就是曲轴弯曲变形的差值了,如果其值大于, 那么曲轴弯曲的比较严重了,为了确保发动机的正常运行,需要及时更换曲轴。 活塞连杆组的检查。 对应活塞部位的检查,主要是检查其活塞销座的尺寸和裙部直径等是否发生了变化,或者是否在使用过程中发生了堵塞等。其主要的检查方法一般有两种,第一种检查方法是用千分尺进行测量,通过测量裙部直径的大小和活塞汽缸磨损部位值的大小,将这两个测得的数据相减,然后和配缸间隙值进行比较,如果差值大于, 则说明活塞磨损比较严重,不能够再使用啦。另一种方法是塞尺进行测量,通过测量配缸间隙来判断其汽车发动机内部活塞是否可以正常使用。首先将塞尺放入安装气环的环槽内,然后以35N的拉力轻轻转动塞尺,当感到轻微的阻力时停止转动,这样就可以用塞尺测量活塞裙部和活塞侧隙差值的大小,当活塞受到磨损越多时,其相应的差值也越大,当该值超过时,这该活塞不能再使用啦,需要为汽车发动机配备新的活塞。如图2所示。 图2 图3 图4 2 汽车发电机的诊断和维修 发动机失速故障 发动机如果出现了失速故障,其一般表现为发动机转速一会低一会高的情况,而这种情况就是常见的发动机失速故障了。出现这种故障的原因主要是因为点火控制系统出现故障,或燃油喷盘系统出现问题,又或者是整个发动机的进气系统出现了问题等。例如,出现了燃油喷盘系统的故障,很有可能是系统线路接触不稳,油管变形或者燃油滤清器灰层太多等。针对不同的原因,可以采取不同的 措施 进行维修。 其相关的故障排除和维修的方法如下:1)如果是喷油系统出现问题,检查是否是线路接触不良,如果是,则可以调整线路或更换导线的方法进行维修,如果是 机油滤清器盖等太多灰层了,则可以采用清洁滤清器盖的方法进行修复;2)如果是进气管出现了问题,则仔细检查是否有各软管或者其相接的地方出现了漏气,也可以检查PVC阀管子等是否通气正常,如果不是,则可以考虑修复或替换相应的管子;3)针对点火控制系统出现的问题,则需要检查各缸火花塞是否正常工作了。例如,火花塞积累的灰层太多,引起发动机转速不正常,则可以通过彻底清洁火花塞来进行维修。 发动机怠速不良故障 发动机怠速不良故障的现象主要是发动机怠速不稳,停车易熄火。在故障诊断方面,可以先检测发动机燃油压力。将燃油压力表连接到油压检测孔上,起动发动机,油压表指示正常,压力为265kPa,拨掉油压调节器真空管,油压上升到340kPa。上述结果均在标准范围内,说明燃油管路系统无故障。然后再检查气缸压力。预热发动机,温度到85℃,打开节气门,用缸压表测量各缸压力,当压力值均为l1OOkPa左右,各缸压差小干300kPa时,上述情况表明发动机气缸密封性出现了问题。 针对该故障的维修,其方法如下:清洗怠速电动机、节气门体。将怠速电动机、节气门体拆下,彻底清洗各空气通道,并用压缩空气吹净。用万用表测量一下怠速电动机电阻值,电阻为20Ω,在18~24Ω正常范围内。测量节气门位置传感器,输出阻值呈线性变化,且在正常范围内。若发现进气总管内沉积有异物,用缠有麻布的铁线将其清理干净。为彻底根除故障,还可以对喷油器进行清洗、检测。 3 结论 从上面的分析可以看出,本文只是简单的介绍了汽车发动机比较常见的故障以及出现故障的原因和解决的方法。其实,整个汽车发动机的维修覆盖面比较广,其相应的维修技术也比较全面复杂,要熟练的掌握汽车发动机的维修技巧和相关技术,还需要学习和实践很多知识,比如电控燃油系统的检查和维修等,本文就不在此一一赘述。 参考文献 [1]朱鹦文,魏浩,章秦.探究汽车发电机维修和检测技术[J].汽车和科技,2004(1):235-248.

good afternoon, all appraiser committee members. i am xxxx and my supervisor is xxx. with her constant encouragement and guidance, i have finished my paper. now, it is the show time. i will present my efforts to you and welcome any title of my paper is on transformation of parts of speech in translation. i choose this as my topic due to the following reasons. different languages have different standards to distinguish parts of speech. each language has its own special structure. and there are no equivalent parts of speech between different languages. in order to make the target version more idiomatic and standard, the transformation of parts of speech is always used by translators. so the transformation of parts of speech is playing a more important role in english to chinese based on different characteristics of english and chinese. for the above facts, i select the subject of“on transformation of parts of speech”as the title of my hope by studying this topic we can know the importance of the transformation of parts of speech in english to chinese translation. through transformation, we can get the better version and improve the translation way of thinking and expressing is quite different between chinese and english. english is a kind of static languages which tends to use more nouns. while chinese is a dynamic one in which verbs are often when we make translation in english to chinese, we should know this point and shift the parts of , it is an outline of my paper. in the main part of this paper, i divide it into five one presents an introduction to the basic concepts of parts of speech and two discusses the definition of translation and emphasizes the importance of transformation of parts of speech in the course of three gives four basic ways of transformation of parts of speech through illustrative examples. there are transformed english words into chinese verbs, nouns, adjectives and four presents some problems about transformation and gives some advise to solve the five draws some conclusions that transformation between parts of speech is necessary for us to achieve good translation. it is demonstrated that we can have a good master of transformation and improve the translation. in addition, we must continuously study and explore in all kinds of translation ! that is all. thank you!
stant encouragement and guidance, I have finished my paper. Now, it's show time. You and I will work hard to welcome any topic of my thesis is 《Angela carter to mythology research - the female archetype in “new eve passion”, for example》。 I choose this as my topic due to the following Carter (1940-1992) is an outstanding feminist writer whose influence on Britishwomen's writing was “pivotal in this opening and transformation” [“23]. The year 2014 represents the 22”^ anniversary of Angela Carter's death. In those twenty-two years, her works have been widely taught internationally and brought about much critical debate. In a survey conducted by Cristina Bacchilega and Danielle M. Roemer [2],Carter is one of the most commonly taught women writers on North American programs. She has endowed us with an amazingly large number of legacies in her comparatively limited life, setting foot in various fields such as novels,short stories,children stories, dramas, non-fictions and so on. The acute observations with great insights,as well as the devastating wit and poignant mockery in Carter's works have made her stand out as an iconic figure in English literature. Many scholars and critics have devoted themselves to the research on Angela Carter from many perspectives,including gothic, magic realism, feminism,post-modernism and so on. As a prolific writer who is always ready to blur the boundaries between different genres, Carter has left us a wonderful world to delve the emergence of western women's movement as well as the development of feminist criticism in the 1960s,the feminist approach has become a potent weapon for those who are concerned with the emancipation and legal rights of women. Though women's social status has considerably improved due to the contribution made by countless predecessors,the fundamental problem still lingers on. Carter, with her versatile and avant-garde reputation, is best known as a feminist writer. Concerning the dilemmas and predicaments faced by women nowadays,it is very necessary for us to probe into her insightful and penetrating reflections on femininity as well as the relationship between two genders. The Passion of New Eve, as one of Carter's most representative works, is of great value in the research of her feminist thoughts and , is my paper outline. In the main part of this article, I put it into five one is an introduction to the thesis, covering the research background, theobjective and significance as well as the organization of the two presents a broad picture of Angela Carter's life and her works, as well as the background information about The Passion of New Eve. It also reviews previous studies on Angela Carter and her works at home and abroad, summarizing achievements in the past and pointing out new directions in the three conducts a retrospective study on feminism and archetypal criticism. The author attempts to work out the origin and development of feminism, demonstrating the important role feminism plays in Carter's life. Then is the history of archetypal criticism,as well as those classic female archetypes in mythology. Regarding those fossilized and monotonous images as impediments to women's freedom and liberation,Carter endeavors to shatter them in her demythologizing strategy and appeals for a rational attitude toward heterosexual four is the main body of the thesis. Through an in-depth analysis on The Passion of New Eve,it demonstrates Carter's demythologizing of “The Temptress,,,”Mother Goddess“and ”Eve“ respectively in the text. Leilah,the embodiment of Delilah,the famous temptress in the Bible,cannot escape the fate of being objectified by men and herself. By exposing”temptresses“ as mere victims rather than symbols of viciousness. Carter condemns the oppression and exploitation of women in a patriarchal society. ”Mother“ in Beulah serves as a severe satire on those mother goddesses in mythology. Carter smashes the legend by revealing the surgically-made essence of mother and the patriarchal values lurking behind her alleged matriarchal kingdom, warning against the peril and impracticality of extremist her most convincing example goes to Eve, the most important female character in the Bible, Her transformative journey from a chauvinist to a real woman in the story illustrates that gender, rather than a hereditary feature, is the result of social influence and unremitting imitations. Carter concludes the story with proposing ”androgyny“ as a solution to the current problems,implying that mutual respect and understanding is the only way to achieve the harmony between the two five comes to a general conclusion, summarizing the limitations of the theses as well as some suggestions for further ! That is all. Thank you!
Good morning, distinguished professors and teachers, thank you for attending the oral defense. I’m xxx and come from class x. My supervisor is professor Li. I would like to express my deepest gratitude to Prof. his consistent guidance and valuable suggestions, I have finished my paper. Now I will present my efforts to you and gratefully welcome any suggestion.
The title of my paper is xxxxxxxxxxxxx. I choose this as my topic due to the following reasons.
Firstly, I am very interested in the study of ambiguity. Ambiguity is a common phenomenon in all natural languages. As is known to all, in our daily conversations, ambiguity is often employed to achieve the effect of humor, thus creating a relaxing atmosphere and letting people feel at ease. Some jokes caused by ambiguity is very interesting.
Secondly, I have read several articles about ambiguity written by linguistics and scholars. I found my knowledge of ambiguity is very limited, superficial and nonsystematic. What I knew is just the tip of the iceberg. So I plan to learn more about ambiguity by this research.
Thirdly, I found many scholars have carried out numerous studies of ambiguity, but a majority of these studies are focused on single language separately. Articles about comparison between English ambiguity and Chinese ambiguity are not sufficient. So it is necessary to make further study.
For the above facts, I select this title.
Next, I will present the outline of my thesis. It consists of 7 parts.
The first part gives a brief introduction to the ambiguity and structure of the thesis.
The second part is literature review, briefly introducing the development of study of ambiguity and some scholars’s main views.
The third to fifth parts focus on three types of ambiguity in English and Chinese: phonological ambiguity, lexical ambiguity, syntactic ambiguity. In every broad type, I respectively list some detailed branches and cite some vivid English and Chinese examples to explain these ambiguity phenomena. But I put more focus on the third part and point out two differences of ambiguity between English ambiguity and Chinese ambiguity.
The part six will point out positive results by using ambiguity deliberately in daily conversations, advertisements and literary works.
The last part is the conclusion.
I hope by this contrastive research, we will have a better understanding of ambiguity in English and Chinese and apply it to our life and study.
When reading the final draft, I still find my argument is not so comprehensive and improvements are needed. So welcome your precious suggestion.
That’s all. Thank you.

毕业论文答辩自述稿英文版(通用6篇)
转眼间充满意义的大学生活就即将结束,我们都知道毕业生要通过最后的毕业论文,毕业论文是一种、有准备的检验大学学习成果的'形式,那么什么样的毕业论文才是好的呢?下面是我整理的毕业论文答辩自述稿英文版,仅供参考,欢迎大家阅读。
Good morning, all appraiser committee members. I am **** and my supervisor is ***. With her constant encouragement and guidance, I have finished my paper. Now, it is the show time. I will present my efforts to you and welcome any correction. The title of my paper is On Transformation of Parts of Speech in Translation.
I choose this as my topic due to the following reasons. Different languages have different standards to distinguish parts of speech. Each language has its own special structure. And there are no equivalent parts of speech between different languages. In order to make the target version more idiomatic and standard, the transformation of parts of speech is always used by translators.
So the transformation of parts of speech is playing a more important role in English to Chinese based on different characteristics of English and Chinese. For the above facts, I select the subject of“On Transformation of parts of speech”as the title of my paper.
I hope by studying this topic we can know the importance of the transformation of parts of speech in English to Chinese translation. Through transformation, we can get the better version and improve the translation skills.
The way of thinking and expressing is quite different between Chinese and English. English is a kind of static languages which tends to use more nouns. While Chinese is a dynamic one in which verbs are often used.
So when we make translation in English to Chinese, we should know this point and shift the parts of speech.
Next, it is an outline of my paper. In the main part of this paper, I divide it into five parts.
Part one presents an introduction to the basic concepts of parts of speech and transformation.
Part two discusses the definition of translation and emphasizes the importance of transformation of parts of speech in the course of translation.
Part three gives four basic ways of transformation of parts of speech through illustrative examples. There are transformed English words into Chinese verbs, nouns, adjectives and adverbs.
Part four presents some problems about transformation and gives some advise to solve the problems.
Part five draws some conclusions that transformation between parts of speech is necessary for us to achieve good translation. It is demonstrated that we can have a good master of transformation and improve the translation. In addition, we must continuously study and explore in all kinds of translation practices. OK! That is all. Thank you! Please ask questions。

The topic of my thesis is 《Angela carter to mythology research - the female archetype in “new eve passion”, for example》. I choose this as my topic due to the following reasons.
Angela Carter (1940-1992) is an outstanding feminist writer whose influence on Britishwomen's writing was “pivotal in this opening and transformation” [“23]. The year 2014 represents the 22”^ anniversary of Angela Carter's death. In those twenty-two years, her works have been widely taught internationally and brought about much critical debate. In a survey conducted by Cristina Bacchilega and Danielle M. Roemer [2],Carter is one of the most commonly taught women writers on North American programs. She has endowed us with an amazingly large number of legacies in her comparatively limited life, setting foot in various fields such as novels,short stories,children stories, dramas, non-fictions and so on. The acute observations with great insights,as well as the devastating wit and poignant mockery in Carter's works have made her stand out as an iconic figure in English literature. Many scholars and critics have devoted themselves to the research on Angela Carter from many perspectives,including gothic, magic realism, feminism,post-modernism and so on. As a prolific writer who is always ready to blur the boundaries between different genres, Carter has left us a wonderful world to delve into.
With the emergence of western women's movement as well as the development of feminist criticism in the 1960s,the feminist approach has become a potent weapon for those who are concerned with the emancipation and legal rights of women. Though women's social status has considerably improved due to the contribution made by countless predecessors,the fundamental problem still lingers on. Carter, with her versatile and avant-garde reputation, is best known as a feminist writer. Concerning the dilemmas and predicaments faced by women nowadays,it is very necessary for us to probe into her insightful and penetrating reflections on femininity as well as the relationship between two genders. The Passion of New Eve, as one of Carter's most representative works, is of great value in the research of her feminist thoughts and propositions.
Next, is my paper outline. In the main part of this article, I put it into five parts.
Chapter one is an introduction to the thesis, covering the research background, theobjective and significance as well as the organization of the thesis.
Chapter two presents a broad picture of Angela Carter's life and her works, as well as the background information about The Passion of New Eve. It also reviews previous studies on Angela Carter and her works at home and abroad, summarizing achievements in the past and pointing out new directions in the future.
Chapter three conducts a retrospective study on feminism and archetypal criticism. The author attempts to work out the origin and development of feminism, demonstrating the important role feminism plays in Carter's life. Then is the history of archetypal criticism,as well as those classic female archetypes in mythology. Regarding those fossilized and monotonous images as impediments to women's freedom and liberation,Carter endeavors to shatter them in her demythologizing strategy and appeals for a rational attitude toward heterosexual relationship.
Chapter four is the main body of the thesis. Through an in-depth analysis on The Passion of New Eve,it demonstrates Carter's demythologizing of “The Temptress,,,”Mother Goddess“and ”Eve“ respectively in the text. Leilah,the embodiment of Delilah,the famous temptress in the Bible,cannot escape the fate of being objectified by men and herself. By exposing”temptresses“ as mere victims rather than symbols of viciousness. Carter condemns the oppression and exploitation of women in a patriarchal society. ”Mother“ in Beulah serves as a severe satire on those mother goddesses in mythology. Carter smashes the legend by revealing the surgically-made essence of mother and the patriarchal values lurking behind her alleged matriarchal kingdom, warning against the peril and impracticality of extremist her most convincing example goes to Eve, the most important female character in the Bible, Her transformative journey from a chauvinist to a real woman in the story illustrates that gender, rather than a hereditary feature, is the result of social influence and unremitting imitations. Carter concludes the story with proposing ”androgyny“ as a solution to the current problems,implying that mutual respect and understanding is the only way to achieve the harmony between the two genders.
Chapter five comes to a general conclusion, summarizing the limitations of the theses as well as some suggestions for further study.
OK! That is all. Thank you! Please ask questions.

Good morning, distinguished professors and teachers, thank you for attending the oral defense. I’m *** and come from class *. My supervisor is professor Li. I would like to express my deepest gratitude to Prof. his consistent guidance and valuable suggestions, I have finished my paper. Now I will present my efforts to you and gratefully welcome any suggestion.
Firstly, I am very interested in the study of ambiguity. Ambiguity is a common phenomenon in all natural languages. As is known to all, in our daily conversations, ambiguity is often employed to achieve the effect of humor, thus creating a relaxing atmosphere and letting people feel at ease. Some jokes caused by ambiguity is very interesting.
Secondly, I have read several articles about ambiguity written by linguistics and scholars. I found my knowledge of ambiguity is very limited, superficial and nonsystematic. What I knew is just the tip of the iceberg. So I plan to learn more about ambiguity by this research.
Thirdly, I found many scholars have carried out numerous studies of ambiguity, but a majority of these studies are focused on single language separately. Articles about comparison between English ambiguity and Chinese ambiguity are not sufficient. So it is necessary to make further study.
For the above facts, I select this title.
Next, I will present the outline of my thesis. It consists of 7 parts.
The first part gives a brief introduction to the ambiguity and structure of the thesis.
The second part is literature review, briefly introducing the development of study of ambiguity and some scholars’s main views.
The third to fifth parts focus on three types of ambiguity in English and Chinese: phonological ambiguity, lexical ambiguity, syntactic ambiguity. In every broad type, I respectively list some detailed branches and cite some vivid English and Chinese examples to explain these ambiguity phenomena. But I put more focus on the third part and point out two differences of ambiguity between English ambiguity and Chinese ambiguity.
The part six will point out positive results by using ambiguity deliberately in daily conversations, advertisements and literary works.
The last part is the conclusion.
I hope by this contrastive research, we will have a better understanding of ambiguity in English and Chinese and apply it to our life and study.
When reading the final draft, I still find my argument is not so comprehensive and improvements are needed. So welcome your precious suggestion.
That’s all. Thank you.
毕业论文答辩开场白和结束语范文
毕业论文答辩开场白和结束语范文,步入大学以后,我们写论文的机会就更多了,尤其是在毕业的时候,毕业论文是很重要的,和我们能不能顺利拿到毕业证是有关系的,我和大家一起来看看毕业论文答辩开场白和结束语范文。
各位老师、同学大家好!
我来自艺术学院平面设计系06级6班,我叫赵洋,我的论文题目是《浅谈标志设计的品牌意识》,本篇论文是在邓丽老师的指导下完成的,在此,我十分感谢她长期以来对我的精心指导和大力帮助,同时也感谢各位评审老师从百忙之中抽出宝贵时间来参与对我这篇论文的审阅并出席本次答辩。
从大二进行对平面设计的系统学习开始,我接触到了各类图形与文字的设计,并对其变幻莫测的美感产生了浓厚的兴趣,而这些简单又赋有深刻内涵的图形最多又最深刻的表现在了企业与商品的标志设计上。在这个以消费者驱动的时代里,人们开始越来越多的注重自己的精神享受,而一个好的品牌的树立不仅可以满足人们的精神享受,还使得拥有该品牌的企业有一个良好的发展前景。对于标志设计,我们可以将其等同于品牌的形象塑造,当代企业参与市场竞争的正确策略是商品力,销售力和形象力三轴组成,
在实际应用中,应三管齐下,并通过前两者来加强影响力。目前我国企业形象策划搞的火热,但由于商品品种多样化,商品品牌琳琅满目,能够成功将品牌形象树立于人们心中的企业却寥寥无几。所以我想通过对品牌意识的树立的研究来探讨品牌树立的先行者,企业视觉识别系统的核心---标志设计的发展。
为了完成本论文,我进行了大量的资料收集,主要来自网络图书和论文期刊,在邓丽老师的指导下,经过阅读资料,拟定提纲,写开题报告初稿、定稿,毕业论文初稿、修改等一些列程序,于2010年4月正式定稿。
全文总共分为四个部分,约12000字:
第一部分是写品牌的概念和作用,该部分主要通过对品牌概念的介绍和树立品牌的重要性来凸显企业竞争中品牌意识的重要性。
第二部分是主要对现有品牌标志设计的分类研究,通过这一部分可以清楚的认识各种类型的标志设计。并通过这些成功案例来凸显标志设计在品牌策略中的重要性。
第三部分主要是写品牌标志设计的纵向发展,并通过诸多知名品牌标志的发展来加深人们的认识。
第四部分是本篇论文的引伸部分,通过以上的研究来探讨品牌标志的发展趋势。
经过本次论文写作,本人学到了许多有用的东西,也积累了不少经验,但由于本人才疏学浅,能力不足,加之时间精力有限,在许多内容表述、论证上存在着不当之处,与老师的期望还相差甚远,许多问题还有待进行一步思考和探究,借此答辩机会,万分肯切的希望各位老师能够提出宝贵的意见,多指出我的错误和不足之处,本人将虚心接受,从而不断进一步深入学习研究,使该论文得到完善和提高。以上是我对自己的论文简单介绍,请各位老师提问,谢谢。

毕业答辩开场白范文
各位老师,你们好!我叫……来自对外汉语071班,我的论文题目是《小王子》的象征意义。论文是在霍继超老师的指点下完成的,在这里我向霍老师表示深深的谢意,向参加我的论文答辩的各位老师表示衷心的感谢,并对四年来的授课老师表示由衷的敬意。
下面是我将本论文设计的目的和主要内容向各位老师做一个汇报,请各位老师批评指导。
首先,我想谈谈这个毕业论文设计的目的及意义。
写《小王子》的象征意义,是基于以下几种目的,一是让人们在看到小王子后,能够反思自己的精神处境,二是想让处在精神困境的人们走出“成人世界”与“儿童世界”的断层,去寻找使这二元世界衔接的中间道路:即既要发展物质文明,又不忽视精神文明的建设,像《小王子》的作者圣埃克絮佩里一样期盼着“小王子”的顺利回归。“小王子”的回归有助于现代经济社会真正又好又快的和谐发展。
《小王子》是圣埃克絮佩里在二十世纪喊出的口号,更是现代社会所需求的治疗精神的良药。
其次,我想谈谈这篇论文的结构和主要内容。
本设计共分四章。
第一章详细阐述象征的概念、起源及其意义,同时介绍整篇论文以象征为理论基点的意图。
第二章和第三章对《小王子》中各种原型和意象进行系统梳理,并对种种表现进行理论分析。
第四章分析《小王子》中成人世界与儿童世界产生二元对立冲突的深层原因,探讨了现代人的“迷失”与“寻找”主题,并阐述了分析“二元世界”象征意义的价值所在,以期在失去象征化的现代社会里能寻找一条人类精神回归的和谐之路。
最后,我谈谈这篇论文存在的不足。
一,论文的主题思想比较陈旧,没有写出创造性的见解,这篇童话不是一时半会能研究透彻的,随着人阅历的增长,看法应该会明显的不同,思想也会深邃的多。文学是有关人生的学问,所以平时的学习和生活的积累很重要。
二,语言表达不够规范,对与文体的学习是很有必要的。
三,每篇论文都体现了每个人的个性特点,在老师的指点下,我们都可以从中找到自己内在的.不足。
对于这篇论文,我就说到这儿。
谢谢!
毕业答辩是大学生们在大学里的最后一个也是最重要的一个考验,好的开始等于成功了一半,毕业答辩的开场白有着至关重要的作用。

6、论文虽未论及,但与其较密切相关的问题还有哪些?
7、还有哪些问题自己还没有搞清楚,在论文中论述得不够透彻?
8、写作论文时立论的主要依据是什么?
对以上问题应仔细想一想,必要时要用笔记整理出来,写成发言提纲,在答辩时用。这样才能做到有备无患,临阵不慌。
一、答辩技巧
学生首先要介绍一下论文的概要,这就是所谓“自述报告”,须强调一点的是“自述”而不是“自读”。这里重要的技巧是必须注意不能照本宣读,把报告变成了“读书”。“照本宣读”是第一大忌。这一部分的内容可包括写作动机、缘由、研究方向、选题比较、研究范围、围绕这一论题的最新研究成果、自己在论文中的新见解、新的理解或新的突破。做到概括简要,言简意赅。不能占用过多时间,一般以十分钟为限。所谓“削繁去冗留清被,画到无时是熟时”,就是说,尽量做到词约旨丰,一语中的。要突出重点,把自己的最大收获、最深体会、最精华与最富特色的部分表述出来。这里要注意一忌主题不明;二忌内容空泛,东拉西扯;三忌平平淡淡,没有重点。
在答辩时,学生要注意仪态与风度,这是进入人们感受渠道的第一信号。如果答辩者能在最初的两分种内以良好的仪态和风度体现出良好的形象,就有了一个良好的开端。有人将人的体态分解为最小单位来研究(如头、肩、胸、脊、腰等)认为凹胸显现怯懦、自卑,挺胸显示情绪高昂—但过分则为傲慢自负;肩手颈正显示正直、刚强,脊背挺拔体现严肃而充满自信。但过于如此,就会被人看作拘泥刻板保守,略为弯腰有度,稍稍欠身可表示谦虚礼貌。孙中山先生曾说过“其所具风度姿态,即使全场有肃然起敬之心,举动格式又须使听者有安静详和之气”他的这番金玉良言,对我们确实有很大的启发。
在听取教师提问时所要掌握的技巧要领是:
沉着冷静,边听边记
精神集中,认真思考
既要自信,又要虚心
实事求是,绝不勉强
听准听清,听懂听明
在回答问题时所要掌握的技巧是构思时要求每个问题所要答的“中心”“症结”“关健”在哪里?从哪一个角度去回答问题最好?应举什么例子来证明?回答问题的内容实质上是一段有组织的“口头作文”。这就要一、文章应有论点、论据。二、有开头主体与结尾。三、有条理、有
