SpainAbsiract - In this paper, a novel controller for parallelconnectedonline-UPS inverters without control wireinterconnections is presented. The wireless control technique isbased on the well-known droop method, which consists inintroducing P-oand Q-V schemes into the inverters, in order toshare properly the power drawn to the loads. The droop methodhas been widely used in applications of load sharing betweendifferent parallel-connected inverters. However, this methodhas several drawbacks that limited its application, such as atrade-off between output-voltage regulation and power sharingaccuracy, slow transient response, and frequency and phasedeviation. This last disadvantage makes impracticable themethod in online-UPS systems, since in this case every modulemust be in phase with the utility ac mains. To overcome theselimitations, we propose a novel control scheme, endowing to theparalleled-UPS system a proper transient response, strictlyfrequency and phase synchronization with the ac mains, andexcellent power sharing. Simulation and experimental resultsare reported confirming the validity of the proposed . INTRODUCTIONThe parallel operation of distributed Uninterruptible PowerSupplies (UPS) is presented as a suitable solution to supplycritical and sensitive loads, when high reliability and poweravailability are required. In the last years, many controlschemes for parallel-connected inverters has been raised,which are derived from parallel-schemes of dc-dc converters[I], such as the master-slave control [2], or the democraticcontrol [3]. In contrast, novel control schemes have beenappeared recently, such as the chain-structure control [4], orthe distributed control [ 5 ] . However, all these schemes needcontrol interconnections between modules and, hence, thereliability of the system is reduced since they can be a sourceof noise and failures. Moreover, these communication wireslimited the physical situation ofthe modules [6].In this sense, several control techniques has been proposedwithout control interconnections, such as the droop this method, the control loop achieves good power sharingmaking tight adjustments over the output voltage frequencyand amplitude of the inverter, with the objective tocompensate the active and reactive power unbalances [7].This concept is derived from the power system theory, inwhich the frequency of a generator drops when the powerdrawn to the utility line increases [8].0-7803-7906-3/03/$ 02003 IEEE. 1637However, this control approach has an inherent trade-offbetween voltage regulation and power sharing. In addition,this method exhibits slow dynamic-response, since it requireslow-pass filters to calculate the average value of the activeand reactive power. Hence, the stability and the dynamics ofthe whole system are hardly influenced by the characteristicsof these filters and by the value of the droop coefficients,which are bounded by the maximum allowed deviations ofthe output voltage amplitude and , when active power increases, the droopcharacteristic causes a frequency deviation from the nominalvalue and, consequently, it results in a variable phasedifference between the mains and the inverter output fact can be a problem when the bypass switch mustconnect the utility line directly to the critical bus in stead ofits phase difference. In [9], two possibilities are presented inorder to achieve phase synchronization for parallel lineinteractiveUPS systems. The first one is to locate a particularmodule near the bypass switch, which must to synchronizethe output voltage to the mains while supporting overloadcondition before switch on. The second possibility is to waitfor the instant when phase matching is produced to connectthe , the mentioned two folds cannot be applied to aparallel online-UPS system, since maximum transfer timeought to be less than a % of line period, and all the modulesmust be always synchronized with the mains when it ispresent. Hence, the modules should be prepared to transferdirectly the energy from the mains to the critical bus in caseof overload or failure [lo].In our previous works [11][12], we proposed differentcontrol schemes to overcome several limitations of theconventional droop method. However, these controllers bythemselves are inappropriate to apply to a parallel online-UPS system. In this paper, a novel wireless control scheme isproposed to parallel different online UPS modules with highperformance and restricted requirements. The controllerprovides: 1) proper transient response; 2) power sharingaccuracy; 3) stable frequency operation; and 4) good phasematching between the output-voltage and the utility , this new approach is especially suitable for paralleled-UPS systems with true redundancy, high reliability andpower availability. Simulation and experimental results arereported, confirming the validity of this control . 1. Equivalenl cimuif ofan invener connecled 10 a bust"Fig. 2. P-odraop . REVlEW OF THE CONVENTIONAL DROOP METHODFig. 1 shows the equivalent circuit of an inverter connectedto a common bus through coupled impedance. When thisimpedance is inductive, the active and reactive powers drawnto the load can be expressed asEVcosQ - V2 Q=where Xis the output reactance of an inverter; Q is the phaseangle between the output voltage of the inverter and thevoltage of the common bus; E and V are the amplitude of theoutput voltage of the inverter and the bus voltage, the above equations it can be derived that the activepower P is predominately dependent on the power angle Q,while the reactive power Q mostly depends on the outputvoltageamplitude. Consequently, most of wireless-control ofparalleled-inverters uses the conventional droop method,which introduces the following droops in the amplitude Eand the frequency U of the inverter output voltageu = w -mP (3)E = E ' - n Q , (4)being W* and E' the output voltage frequency and amplitudeat no load, respectively; m and n are the droop coefficientsfor the frequency and amplitude, , a coupled inductance is needed between theinverter output and the critical bus that fixes the outputimpedance, in order to ensure a proper power flow. However,it is bulky and increase:; the size and the cost of the UPSmodules. In addition, tho output voltage is highly distortedwhen supplying nonlinezr loads since the output impedanceis a pure is well known that if droop coefficients are increased,then good power sharing is achieved at the expense ofdegrading the voltage regulation (see Fig. 2).The inherent trade-off of this scheme restricts thementioned coefficients, which can be a serious limitation interms of transient response, power sharing accuracy, andsystem the other hand, lo carry out the droop functions,expressed by (3) and (4), it is necessary to calculate theaverage value over one line-cycle of the output active andreactive instantaneous power. This can be implemented bymeans of low pass filters with a smaller bandwidth than thatof the closed-loop inverter. Consequently, the powercalculation filters and droop coefficients determine, to a largeextent, the dynamics and the stability of the paralleledinvertersystem [ conclusion, the droop method has several intrinsicproblems to be applied a wireless paralleled-system ofonline UPS, which can he summed-up as follows:Static trade-off between the output-voltage regulation(frequency and amplitude) and the power-sharingaccuracy (active an4d reactive).2) Limited transient response. The system dynamicsdepends on the power-calculation filter characteristics,the droop coefficients, and the output of ac mains synchronization. The frequency andphase deviations, due to the frequency droop, makeimpracticable this method to a parallel-connectedonline UPS system, in which every UPS should becontinuously synchronized to the public ac )3)111. PROPOSED CONTROL FOR PARALLEL ONLINE UPSINVERTERSIn this work, we will try to overcome the above limitationsand to synthesize a novel control strategy withoutcommunication wires that could be appropriate to highperformanceparalleled industrial UPS. The objective is toconnect online UPS inverters in parallel without usingcontrol interconnections. This kind of systems, also namedinverter-preferred, should be continuously synchronized tothe utility line. When an overload or an inverter failureoccurs, a static bypass switch may connect the input line tothe load, bypassing the inve:rter [14][15].Fig. 3 shows the general diagram of a distributed onlineUPS system. This system consists of two buses: the utilitybus, which is connected lo the public ac mains; and thesecure bus, connected to the distributed critical loads. Theinterface between these buses is based on a number of onlineUPS modules connected in parallel, which providescontinuously power to the: loads [16]. The UPS modulesinclude a rectifier, a set of batteries, an inverter, and a staticbypass ac mainsutility busI I Ij distributed loads !Fig. 3. Online distributed UPS /I 4(4Fig. 4. Operation modes of an online UPS.(a) Normal operation. (b) Bypass operation. (c) Mains failureThe main operation modes of a distributed online UPS1) Normal operation: The power flows to the load, fromthe utility through the distributed UPS ) Mains failure: When the public ac mains fails, theUPS inverters supply the power to the loads, from thebatteries, without operation: When an overload situation occurs,the bypass switch must connect the critical busdirectly to the ac mains, in order to guarantee thecontinuous supply of the loads, avoiding the damageof the UPS this reason, the output-voltage waveform should besynchronized to the mains, when this last is are listed below (see Fig. 5):3)Nevertheless, as we state before, the conventional droopmethod can not satisfy the need for synchronization with theutility, due to the frequency variation of the inverters, whichprovokes a phase obtain the required performance, we present a transientP-w droop without frequency-deviation in steady-state,proposed previously by OUT in [ 111w=o -mP (5)where is the active power signal without the dccomponent,which is done by. -I t -1sP= p ,( s + t - ' ) ( s + o , )being zthe time constant of the transient droop transient droop function ensures a stable frequencyregulation under steady-state conditions, and 'at the sametime, achieves active power balance by adjusting thefrequency of the modules during a load transient. Besides, toadjust the phase of the modules we propose an additionalsynchronizing loop, yieldingo=w'-m%k,A$, (7)where A$ is the phase difference between the inverter and themains; and k, is the proportional constant of the frequencyadjust. The steady-state frequency reference w* can beobtained by measuring the utility line second term of the previous equality trends to zero insteady state, leading tow = w' - k4($ -@'), (8)being $and $* the phase angles of the output voltage inverterand the utility mains, into account that w = d $ / d t , we can obtain thenext differential equation, which is stable fork, positived$ *dt dt- + km$ = - + k,$' . (9)Thus, when phase difference increases, frequency willdecrease slightly and, hence, all :he UPS modules will besynchronized with the utility, while sharing the power drawnto the .

Block diagram of the proposed a band-pass filter. In a similar way, the averagereactive power is obtained, hut in this case the output-voltagemust be delayed 90 degrees, and using a low-pass order to adjust the output voltage frequency, equation(7) is implemented, which corresponds to the frequencymains drooped by two transient-terms: the transient activepower signal term; and the phase difference term, whichis added in order to synchronize the output voltage with theac mains, in a phase-locked loop (PLL) fashion. The outputvoltageamplitude is regulated by using the conventionaldroop method (4).Finally, the physical coupled inductance can be avoided byusing a virtual inductor [17]. This concept consists inemulated an inductance behavior, by drooping the outputvoltage proportionally to the time derivative of the outputcurrent. However, when supplying nonlinear loads, the highordercurrent-harmonics can increase too much the outputvoltageTHD. This can be easily solved by using a high-passfilter instead of a pure-derivative term of the output current,which is useful to share linear and nonlinear loads [I 1][12].Furthermore, the proper design of this output inductance canreduce, to a large extent, the unbalance line-impedanceimpact over the power sharing . SIMULATION AND EXPERIMENTARELS ULTSThe proposed control scheme, (4) and (7), was simulatedwith the parameters listed in Table 1 and the scheme shownin Fig. 6, for a two paralleled inverters system. Thecoefficients m, n, T, and kv were chosen to ensure stability,proper transient response and good phase matching.

This characteristik let us to apply the controller tothe online UPS paralleled I-kVA UPS modules were built and tested in order toshow the validity of the proposed approach.

The controllers of these inverters werebased on three loops: an inner current-loop, an outer PIcontroller that ensures voltage regulation, and the loadsharingcontroller, based on (4) and (7). The last controllerwas implemented by means of a TMS320LF2407A, fixedpoint40 MHz digital sigrial processor (DSP) from TexasInstruments (see Fig. 8), using the parameters listed in TableI.

Against this background, if is of real significance to conduct a thermal computation of 300MW once-through boilers in variable working conditions and undertake an analysis of the properties thereof. The fact that EXCEL is employed as a tool for calculating boiler heat is based on its powerful data formatting and formulae input functions. EXCEL’s built-in VBA programming tool enables the former to approximate charts by virtue of formulae, thus rendering some data which require chart look-up more easily assessable and more accurate. In addition, EXCEL’s chart-generation function presents in a more direct fashion the changing trend of data to facilitate date analysis. Thermal computation of the heated surfaces of the boiler with the use of the EXCEL software has helped achieve the semi-automation of boiler thermal computation for verification and adjustment purposes by improving the speed and accuracy of the computation. Using as its computation object the 935 ton/hr once-through boiler manufactured by the Shanghai Boiler Factory in 1971, based on the standard approach in thermal computation of boiler generating units, incorporating the latest studies on the boiler industry in recent years and utilizing the modern office software of EXCEL, this paper is a result of the thermal computation of multiple working conditions of the 300MW once-through boiler and optimization of the computational formulae of certain parameters which culminated in a study and analysis of the data obtained through the computation. It provides useful references for the safe and economical operation of boilers. 关键词：直流锅炉;热力计算；EXCEL软件；变工况；特性分析Key Words: once-through boiler; thermal computation, EXCEL software; variable working conditions; analysis of properties

论文翻译方向写电影名翻译或者是台词翻译之类的都挺多的，但也有利有弊，你可以借鉴下看别人从哪些方面分析的，然后自己选几个最近新出的电影，再立角度写论文。这样就不会没新意了。那些已经被写烂了的电影就不要写啦，选最新最近的影片应该就好很多的。
电影翻译中文化意象的重构、修润与转换电影翻译中文化意象重构能及时有效地吸引广大观众。而对文化意象作恰如其分的修润,能使译文在有限的时间内传达于观众。东西方文化的差异导致了某些文化意象的不等值,采用直译手法处之,会使观众难以认同。关键词:电影翻译;文化意象;寓意;重构;修润;转换中国的电影翻译事业已走过了五十多年辉煌的历程。在这半个世纪中,电影翻译工作者给广大观众奉献出了许多优秀的译制片,观众从这些优秀的译制片中不仅领略、了解到了异国的风土人情,同时也感受到了语言给人带来的无穷魅力。许多优秀译制片中的精彩对白已成为中国观众争相传诵的佳句。如“面包会有的,一切都会有的”。(前苏联影片《列宁在一九一八》)曾鼓舞了几代身处逆境中的中国观众。由此可见,电影作为大众传媒,其社会效应是无可估量的。然而,在学术领域内,由于受世俗偏见的影响,电影翻译研究却颇受冷落,翻译研究人员似乎“完全把这一领域给忽略了。”[1](P99)为此,我国著名影视翻译界学者钱绍昌教授撰文指出:“翻译界对影视翻译的重视远不如文学翻译。”而这“与影视翻译的社会作用不相称。这一现象亟应引起翻译界的注意。”[2](P61)鉴于此,本文拟从语言的角度来探讨电影翻译中文化意象的重构、修润与转换。一、语言与文化意象语言(Language)不仅是人类思想感情表达与交流的工具,而且是文化的组成部分,是文化的载体。语言能真切地反映一个国家、一个民族的生态地域、政治经济、物质文化、宗教信仰、风俗习惯等。不同的语言决定了不同民族的不同思维方式,行为方式以及语言表达方式。语言在有声电影中是必不可少的组成部分,因为声画同步的视听艺术手段能最大程度地模拟现实,创造出酷似“真实”的艺术时空。如中国观众非常熟悉的《简爱》、《王子复仇记》、《叶塞尼亚》等优秀译制片中那玲珑别致、清晰明亮、颇具异国风情的语言,逼真、自然、随意,充满了生活气息。因而这些精彩的对白、片段令人百听不厌,久久不能忘怀,它们留给观众余韵不尽的美的享受。文化意象(Culture image)是“一种文化符号,它具有了相对固定的独特的文化含义,有的还带有丰富的意义,深远的联想,人们只要一提到它们,彼此间立刻心领神会,很容易达到思想沟通。”[3](P184)物象(Physical image)与寓意(Connotation)是意象(Image)的两个重要的组成部分。物象是信息意义的载体,是形成意象的客观事实;寓意是物象在一定语言文化环境中的引伸意义。意象的功能即能在不同的语境中,“以具体来表现抽象,以已知或易知来启迪未知或难知。”[4](P137)如宋代大诗人苏轼在其著名的“前赤壁赋”中用蜉蝣这种朝生暮死的小昆虫来比喻人生的短暂,人很渺小:“寄蜉蝣于天地,渺沧海之一粟。”[5](P509)英语谚语It is the last straw that breaks the camel’s back.[6](P1578)意为“骆驼负载过重时,再加上一根稻草也会把它压死。”谚语中意象词语the last straw “最后一根稻草”,生动形象地寓意为“某事或某物使人到了忍无可忍的极点。”二、重构文化意象译制片又称翻译片,顾名思义,一些国外优秀的影片必须通过翻译方能为中国观众所接受。电影翻译与其它文学作品翻译具有共同性,即用形象化的语言来表达形象思维中高超的艺术意境。但电影翻译又有区别于其它翻译的特殊性,即其译文要做到能见之于文,形之于声,达之于观众。著名翻译家Nida指出:“语言是文化的一部分,任何文本的意义都直接或是间接地反映一个相应的文化,词语意义最终也只能在其相应的文化中找到。”“文化的不同几乎很自然地体现在语言上的不相同。”[7](P28)汉语、英语分属两大不同的语系。汉语是象形文字而英语是一种字母文字。要在这两种截然不同的语际间进行成功切换,这对电影翻译工作者来说不是件易事。但研究表明老一代电影翻译工作者不仅给观众留下了许多耐人寻味的优秀译制片,同时也给电影翻译研究留下了不少值得研究的课题。笔者80年代初第一次在电视上看到英国电影Red Shoes播放时被译成“红舞鞋”,觉得也无可厚非。此片主要讲述了英国一名芭蕾舞女演员面对爱情与事业而不能作出正确抉择,最终走向断崖的凄惋的故事。尽管“红舞鞋”正确无误地译出了英文的原意,也紧扣剧情,但直译的平铺直叙,没有更深的寓意。观众如果光看片名,确实难以激起任何联想的波澜。80年代后期,在一次外国优秀影片巡回展的大幅广告上Red Shoes这部英国影片片名被译成了“红菱艳”,细细品味“红菱艳”这一译文,译者把那双纤巧的红舞鞋比作了中国观众妇孺皆知的红菱。它寓意红菱虽生长于浊水污泥,却娇艳迷人,特别是那两只弯弯的红菱角,犹如中国古代女子的三寸金莲,三寸金莲虽然小巧,但凝聚了多少女子的血泪,有的甚至为之付出了生命的代价。因此“红菱艳”这一片名隐含穿着如红菱般舞鞋的舞女艳丽却薄命。译者把这一极具中国文化特色的文化意象“红菱”注入其翻译中,从而成功地重构了一幅为广大中国观众所熟悉、能会意、肯接受的崭新的文化意象。文化意象重构(Reconstruction of Culture Image)这一巧夺天工的翻译手法在电影翻译中随处可见。如美国电影Waterloo Bridge这一片名原意为“滑铁卢桥”。众所周知,1817年英国在泰晤士河上出资建造了滑铁卢桥,以此来纪念威灵顿公爵指挥英国军队打败拿破仑而取得的滑铁卢战役的胜利。如果依据英文直译成“滑铁卢桥”,乍一看,观众定会认为这是部与拿破仑打仗有关的战争片或介绍与该桥建筑有关的纪录片。但看过此片的观众都知道这是一部感人至深的爱情片。影片描绘了第一次世界大战期间,年轻漂亮的女演员玛拉在滑铁卢桥上结识了青年军官罗依,并成了恋人。而后,玛拉获悉罗依战死疆场,痛不欲生,为了生存沦落为妓。当罗依奇迹般地出现时,她无法面对现实,为了爱情和名誉,她再次来到与罗依初恋的地方,丧生在车轮滚滚的滑铁卢大桥上。在中国几千年的文化史中,有着许多与之相仿的神话传说。如牛郎织女的“鹊桥相会”,陕西省蓝田县一年一度的“蓝桥相会”等。而“蓝桥相会”的传说与Waterloo Bridge故事情节有着许多异曲同工之处。所以译者把原名“滑铁卢桥”译成了“魂断蓝桥”,这样做不仅避开了中国观众由于地城文化差异、历史背景知识缺乏而引起的迷域;而且“蓝桥”这一隐含中国文化的意象能使观众一看到片名即刻领悟到这是部关于爱情的电影。电影翻译中文化意象重构的意义在于它能及时有效地达到使译文与观众勾通,使观众心领神会的效果,由此来吸引广大的影迷,创造译制片票房纪录的新高。仔细认真研究电影翻译中文化意象重构这样的翻译手法会不时令人拍案称奇。三、文化意象的修润由于中外观众知识面及文化背景等方面存在着巨大的差异,电影翻译工作者应尽可能地帮助观众去理解那些与一个民族的历史、地域文化、宗教习俗等有着密切相关的语言现象。电影翻译中如果对某些特定文化意象不作任何修润(Modification of Cultural Image)处理,就事论事直译,会造成这一文化意象的缺损,文化涵义支离破碎。英国电影《魂断蓝桥》[8]一开始,有这样一段画外音: Announceer’s Voice: At 11:15 this morning, the Prime Ministeer, speaking to the nation from Numbeer Ten Downing Street,announced that Great Britain is at war with Germany.广播员的声音:今天上午11点15分,首相在唐宁街10号向全国发表了讲话,宣布英国与德国处于交战状态。 应该指出此例忠实地译出了原文的字面层意义。但对“唐宁街10号”这一隐含文化意象地名不作些补充说明的话,相信绝大多数中国普通观众会茫然不知其所云。其一、观众不知道这个“唐宁街10号”在什么地方?其二、他们更不知道广播员在这里特地提及这个地名有何特别的寓意?为了使电影译文能在有限的时间内达之于广大观众。译者宜对上述译文作恰如其分的增补修润,如:今天上午11点15分,首相在唐宁街10号———英国首相府邸向全国发表了讲话,宣布英国与德国处于交战状态。通过增补“英国首相府邸”,观众这才真正认识到了“唐宁街10号”的“庐山真面目”。至此,“唐宁街10号”所隐含的意象立体地展现在观众的面前,观众才真正懂得具有典型地起域文化地名“唐宁街10号”的全部文化内涵。又如:Peter: Oh, this? Well, I like privacy when I retire. Yes, I’m very delicate in that respect. Prying eyeeees annoy me. Behold the walls of Jerichho! Err, maybe not aaas thick aas the ones that Joshua blew down with his trumpet. I just show you my heart’s in the right place, I’ll give you my best pair of pajamas. Do you mind joining the Israelites?彼得:这个吗?我休息的时候不想被别人干扰,在那方面我很敏感,不想被别人偷看。你看这耶利哥城墙,比不上约书亚用号角吹倒的墙厚,却比它安全多了。你看,我没有号角,为了表示我的公正无私,我把我那套最好的睡衣交给你用吧。你不想做以色列人吗?此例选自英国电影《一夜风流》[9]。这段对白译文非常具有代表性,因为在这段译文中出现了“耶利哥城墙,约书亚,以色列人”这三个与《圣经》历史故事有关的词语。众所周知,东方盛行佛教,尤其是在中国,中国观众对佛教还可略知一二,而对西方文化,特别是西方宗教历史文化就知之甚少了。因而在影片切换的瞬间让中国观众把上述三者的关系联系起来是件难事,他们会搞不懂这“耶利哥城墙”、“约书亚”、“以色列人”之间究竟是什么关系。直译用于上述译文中不仅令中国观众丈二和尚摸不着头脑,同时也失去了电影翻译的真正意义。为使中国观众明白这三个词语间的关系,使原文中所涉及的那些特殊文化意象丰满起来,译者应在电影翻译过程中对这段文字作如下润色:彼得:这个吗?我休息的时候不想被别人干扰,在那方面我很敏感,不想被别人偷看。你看这像《圣经》中的耶利哥城墙,虽比不上《圣经》里以色列人的军长约书亚用号角吹倒的墙厚,却比它安全多了。你看,我没有号角,为了表示我的公正无私,我把我那套最好的睡衣交给你用吧。你不想做以色列人吗?由于对“耶利哥城墙”、“约书亚”、“以色列人”这些出自《圣经》故事的词语增补了必要的文化涵义修润词后,观众不仅了解了这些“典故”的出处,同时在上下语境中也弄明白了最后一个词语“以色列人”的特定意指。修润增强了语言文字在语境中的透明度;增强了文化意象在观众认识理解中的清晰度。四、文化意象的转换语言学家认为世界上各族人看到的同一客观现象,不同的民族语言会给它“刷上不同的颜色”。缘于此,文化意象的错位(Nonequivalence of Culture Image)会具体表现为作为喻体的文化意象上的差异。换言之,在一种文化传统中一个具有正面寓意的美好文化意象在另一种文化里却成了反面寓意的丑陋文化意象。如英国电影《呼啸山庄》[10]中有这样一个片断:Isabella: It’s a brother’s duty,dear Edgaar, to introduce his sisteer to some other type than fops and pale young : Oh, you want a dragon?Isabella: Yes, I do. With a fiery mustache.依莎贝拉:这是一个哥哥的义务,亲爱的埃得加,你总不能把自己的妹妹介绍给那些花花公子或弱不禁风的年轻诗人吧。埃得加:哦,你该不是想嫁一个龙骑兵吧?依莎贝拉:是的,还长着火红的大胡子。在上述翻译中“dragon”是一个关键词。在英语语言中,“dragon”作“魔鬼”解释。每当提及此词,西方人的思想意识中立刻会呈现出一只面目狰狞的魔鬼正张牙舞爪地扑向人间,由此不难看出“dragon”在西方语言文化中隐含贬义。而在中国文化中“龙”字象征着“高贵,至高无上”等意,昔日中国人称皇帝为“真龙天子”。因此与“龙”字相关的词语绝大多数具有崇敬之意。如中国人称自己为“龙的传人”;祈盼着自己的子女将来有出息为“望子成龙”等。“dragon”在东西方语言中,其文化意象的寓意是绝然相反的。简言之,它们的物象虽同,但寓意却完全相异。由此可见用“龙骑兵”来硬译“dragon”一词显然不妥当。因为当中国观众在观赏影片时忽尔听到“龙骑兵”这一词语,他们肯定即刻会联想到“他”可能是个“皇家骑兵”。但依莎贝拉的回答却又使观众对影片的阐释如坠云雾。观众不禁要问:这个堂堂正正的“皇家骑兵”怎么会是“长着火红的大胡子”呢?在中国传统历史文化中,只有那些三头六臂的怪物才有一张可怕的绿眉毛、红胡子嘴脸。如此生搬硬套不仅不能处理好东西方语言文化中意象错位这一棘手问题,同时也不能传神地译出这段对白的真实含义,反而给上下文语义的贯通设置了语言障碍。因此,例中埃得加与依莎贝拉的最后一段对话不妨翻译如下: Edgar: Oh, you want a dragon?哦,你该不是想嫁给一个野蛮人吧?Isabella: Yes, I do. With a fiery mustache.是的,还长着火红的大胡子。由于东西方文化的差异,电影翻译中许多英语词语若直接硬译,会令广大中国观众无法接受与认同。此外,电影翻译文本受电影画面切换时间的限制,不能像翻译文学作品那样,可以在一些晦涩难懂之处作些注释,所以对白译文一定要让观众一听、一看即能明了。译者应立足于本国观众,从观众领略欣赏译制片的艺术角度出发,选用本民族语言中与原片艺术最相似、最贴近的、为本国观众所熟悉的、易于接受的词语和文化意象来进行电影翻译。
这个题目挺好的~~挺有研究价值的。应该多举些例子，比如说一些经典电影的字幕什么的。老友记也是比较经典的，祝你成功哦~~
电影字幕翻译漫谈 随着宽带在中国的普及，mpeg4技术的广泛应用，很多由DVD压缩的DVDRIP影片以惊人的速度在互联网间传播。事实上，在中国，大部分人都不具备直接欣赏外语影片的能力，而很多DVDRIP影片却恰恰是原声发音、外语字幕。电影字幕的翻译作为DVDRIP影片的一个关键部分，正逐渐得到人们的关注。这其中包括正版或盗版DVD碟片上rip下来的vobsub字幕，以及由网友自发翻译的srt格式字幕。 中文字幕翻译的特点 中文字幕和中文配音在翻译要求上是不一样的。比如我们所熟知的上译厂，配音要求讲究口型一致，句子符合中国的口语规范，其优势是方便观众看电影，直接就能听懂，而不用费力看字幕。其缺点也显而易见：由于口型上的要求，不得不对句子进行缩减或扩充；由于外国历史文化的差异，很多双关、幽默的意思难以表达，不得不舍弃这些句子的翻译。 以《魔羯星一号》中英双语版为例，可以明显看出中文配音和中文字幕的差异。其中有一段剧情是母亲给孩子说英语绕口令，如果配音直接翻译的话，很难做到押韵，于是改为讲故事。另一段剧情是一个宇航员边爬山边讲笑话，这个笑话是有寓意的，直接翻译成配音的话，很多观众会感觉莫名其妙，于是配音版改为宇航员边爬山边呼救。该片配音版中很多幽默的成分都改掉了，这样就损失了很多欣赏电影的乐趣。 电影字幕就较好处理这些问题。首先，没有口型限制，字幕可以按原文直接翻译，而幽默和一语双关的意思可以使用注释来解决。当然，最好的方法还是学好外语，直接观看外语字幕的影片。而在个人条件不允许的情况下，字幕翻译还是最大限度表达英文意思的最佳方法。 没有硝烟的战场 经常看DVDRIP影片的网友都知道，公开的中文字幕库有几大网站。射手网稳坐字幕网站的头把交椅，其特点是：允许自由上传，字幕多而杂。正因为字幕多，同一影片有好几个版本的字幕，造成网友下载时无所适从，网站设有的评分系统基本上形同虚设，因为大部分网友为下载字幕而来，而等到看完影片，早就把给字幕打分的事忘到九霄云外了。射手网设有TLF、汉风、新视界、牛过四大字幕网站的友情搜索链接，射手网上没有的字幕，可以在这些字幕网站上继续搜索。这四大字幕网站均是以论坛为依托的，各自有较强翻译能力字幕小组。除以上提到的四个论坛，更有伊甸园、行星等影视论坛的字幕组，虽没有独立的字幕网站，但也具备很强的字幕翻译能力，实力不容小视。 同行是冤家，这话一点不假，在字幕界尤为显著。字幕界有一条不成文的规定，就是：每个字幕组成员不允许加入其他字幕组，或者以其他字幕组的名义发布自己的翻译作品。曾有个别成员以身试法，均被开除组籍。每个字幕组在各自论坛都有专门的活动版块，这些版块是仅有小组成员才能进入的，这已经是半公开的秘密。每逢热门大片上市，这些秘密基地里顿觉杀气腾腾。各字幕组紧锣密鼓，召开工作会议，分配任务，争取在第一时间发布字幕。领到任务的小组成员常常会为此通宵达旦，连续工作十多个小时。而几天后，各论坛出品字幕质量的比较，又成为各字幕小组讨论的热点。更有好事之人，通过随机挑选句子进行比较的方式，评价各论坛出品字幕的优劣。所以，热门大片的翻译无异于一场激烈的战斗，而连年战争的结果，使得几大字幕小组和所在的论坛人气飙升，翻译人员欢欣鼓舞，最终形成N赢的局面。 几块善意的砖头 不客气地说，现在中文字幕的翻译状况相当混乱，由于没有一个类似rip字幕的统一标准加以规范，加上不少翻译人员带着急功近利的心理，把翻译字幕当作得到积分的手段来应付差使，造成字幕质量参差不齐。单兵作战，除了个别翻译质量很高外，非字幕组的散兵游勇普遍缺乏翻译经验，字幕存在不少问题。而有些字幕组只求数量，根本不论质量，只要翻完就皆大欢喜，而没有一个较完备的质量监管机制来进行约束。不用仔细核对，仅一遍影片看下来，平均每部影片的明显错误（比如错别字、格式错）都在10个以上。近期汉风HTS的字幕出得不多，仅从看到的几个来说（其中有些还是很早以前翻译的字幕），错误还能控制在一定范围内。概括起来，个人认为，字幕界存在以下四大弊病（发现标题起得居然很押韵，嘿嘿）： 1、一人包揽翻译校对 初期的牛过论坛字幕组（即汉风HTS字幕组的前身）曾一度辉煌，并定下专门的翻译、校对制度，在字幕头尾标明翻译、校对人员，并规定翻译、校对不能是同一个人。其他论坛的字幕组也纷纷采用这种形式，但遗憾的是，只学到了形式，却没有实质，大部分字幕组出品的字幕，翻译、校对都是一个人。 我如果说，一人既翻译又校对，一定比翻译、校对分别由两人作的字幕质量差，这话肯定是不负责任的。有些个人独立翻译校对的字幕甚至比两人翻译校对的字幕质量上高很多。但大家想一想，有多少人翻译完字幕后会真的自己进行校对？校对自己的字幕，又能找到多少错误？以我以往翻译的经验来说，仅翻译过程就反反复复看了N遍的电影，已经是心力交瘁，翻译完成后很难会有心情再看一遍寻找错误。而且自己翻译中的错误，自己也很难找得到。这就是为什么要提倡字幕组成员互相校对。 就是我提到的翻译、校对机制，本身也是形式，如果此文一出，很多论坛的字幕组纷纷改为多人校对，而质量上没有提高，那岂不还是形式主义？真要想保住字幕质量，非要有较具体的标准不可，把每个字幕组出品的字幕错误限制在几个以内，超过了会有一个惩罚措施。 2、人力资源严重浪费 由于各论坛自行其事，没有一个统一的安排规划，造成原本不充裕的翻译人员，都集中在热门商业片的翻译上。《指环王》系列、《黑客帝国》系列都有4个以上的字幕组同时在作，很多已经有中文字幕的影片，新出了另一个RIP版本，翻译人员未经查找，又重新翻译。有些字幕组曾结成过翻译联盟，统一组织安排工作，避免重复翻译，但因任务分配、翻译能力等方面的原因，最终只得恢复各自为政的状态。 我有一个梦想，所有的中文字幕组织联合起来，建立专门的字幕翻译分配网站，对热门大片采取各字幕组轮流翻译的方法，其他影片的翻译，由个人自行申请。另外再制定统一的字幕翻译校对规则，对字幕翻译细节进行规定，确保字幕质量。当然，这只是我的梦想，真正实施起来，涉及到网站管理、任务分配、联系沟通，尤其是涉及到各字幕组自身利益，难度相当大。想要逐步实现的话，各字幕组负责人之间的交流和沟通是首要任务。 3、长片老片翻译嫌累 现在的字幕翻译普遍采取个人申请制，大家根据兴趣爱好，自行选择影片翻译。在没有特别感兴趣的情况下，通常浪漫爱情片、动作枪战片等因句子少，情节吸引人，翻译难度小而很受欢迎。而1500句以上的长片和黑白老片、记录片、文艺片因对话多，情节枯燥，翻译难度大而少人问津。当然，这些情况并非绝对，我记得我就曾经投机翻过一个200多句的老片。总的说来，这其实是个人兴趣与字幕需求的矛盾。字幕组的成立就建立在兴趣爱好的基础上，只要愿意，重复翻译又有何不可？强扭的瓜不甜，硬要别人翻译不喜欢的影片有违“兴趣爱好”这一理念。在不考虑兴趣的前提下，可以通过论坛奖励制度的适当倾斜来对翻译冷门片的网友进行额外奖励，以解决长片、老片无人翻译的问题。 4、新丁不来老人隐退 人的兴趣爱好是会发生变化的，字幕组成立到一定时间，很多老成员在经过十几部影片的翻译校对后，会逐渐丧失当初的翻译热情，参与翻译的人逐渐减少，不少处于半隐退状态。现在汉风论坛的积分制＋流量制，解决了部分翻译懈怠问题，但终究不是长久之策。我心目中比较好的字幕组模式，应该是类似于“青年志愿者”到边疆教书，几年后，老成员陆续退出，而新成员不断加入，当然，有愿意长期服务的，更是欢迎。在字幕翻译上，对人才的需求从来都是只多不少。可惜的是宣传力度仍然不够，仅在论坛内部招收新成员，难以维持新鲜血液的不断输入。希望能对外在各高校BBS和专业英语论坛广泛招收此类成员，毕竟，这种耗人精力的工作不是每个人都能长期坚持的。本文专为招收汉风字幕组新成员而作，请在转载的同时，请勿删除末尾的广告文章。 一、制作字幕需要的各项要求 认真－－我把这一点放在首要位置，英语水平差、中文表达能力不行，这都是可以原谅的，唯独粗心大意犯的低级错误不可谅解。有人提议说要提高进字幕组的门槛，谬矣，现在人手是大大的不够，不能再提高了。大部分的字幕质量低下并非是英语差造成的，而是没有一个认真的态度。私以为，一个字幕的优劣，认真态度占40％，翻译经验占20％，英语程度占19％，中文表达占21％。其中翻译经验包含了中英文表达以及工具软件和网络搜索在翻译中的应用，这些经验方面的知识，新手刚开始翻译不会注意，时间一长，慢慢就有体会了。 英语－－通常各大论坛字幕组对外招人，要求英语程度为六级，这的确吓倒了很多准备尝试字幕翻译的新人。我在这里要更正一下说法，希望能为这些被高门槛吓跑的网友鼓鼓劲。一般来说，电影中的句子比大学英语课本要简单好多。我认为只要是上过大学的学生，不管过没过四、六级考试，借助“金山词霸”等翻译软件，在英语方面都可以达到普通字幕翻译的要求。当然，英语程度是越高越好，尤其是在国外留学、居住的网友更佳，因为有些时候，影片出现一些复杂句式、俚语还有涉及外国历史文化方面的知识，这些不是字典和翻译软件能查到的，这时就体现出英语程度的优势了。 中文－－奇怪的是，明明英译中涉及两种语言，很多字幕组却往往不对中文程度作任何要求。大概是因为我们都是中国人，学了10多年的中文，表达方面应该没有问题。其实不然，英译中对中文表达的要求应该更多些。有些在国外多年的留学生，英语方面很厉害，很多查不到的俚语都不在话下，可翻译出来的字幕却一塌糊涂。大概是适应了英语的表达方式，转回头用中文表达，却好像“英式中文”，不知道他回国后说话会不会也是这样。
