In the 20th century, bridge construction technology evolved and was fueled by the Industrial Revolution. At the turn of the century, steel bridges were riveted together, not bolted; concrete bridges were cast in place, not precast; and large bridge members were built from lacing bars and smaller sections, not rolled in one piece. Plastic had not yet been invented. Construction techniques such as post-tensioning, slurry walls, soil freezing, and reinforced earth walls had not yet been conceived. Surveying was performed mechanically since infrared, optical technology was still 75 years away. Bridge construction is changing as the new millennium begins. New construction techniques and new materials are emerging. There are also new issues facing the bridge building industry relative to the research needs associated with these new techniques and materials. LONG-SPAN BRIDGES Suspension Bridges While suspension bridge building was conducted at a modest pace throughout the 20th century, an unprecedented number of spans of remarkable record lengths were built in the Far East and Denmark. Both the Akashi Kaikyo Bridge in Japan and the Great Belt Bridge in Denmark were completed in 1998. The Akashi Kaikyo Bridge is the largest suspension bridge in the world, with a span of 1991 m, and the Great Belt Bridge is the second largest, with a span of 1624 m. While spans lengths have increased nearly fivefold during the course of this century, they may have reached their physical limits with today’s materials. Research will be necessary to develop the new, ultra-high-strength steel wire or carbon fiber wire required to build the longer main suspension cables that will make it possible to increase span lengths to beyond 2000 m. As we enter the new millennium, rehabilitation and ongoing maintenance of the existing suspension bridges must continue as well. Recent rehabilitation measures for the main cables and suspension systems of these bridges have uncovered degradation through corrosion and hydrogen embrittlement. Research is needed to determine the remaining useful service life of suspension bridge cables and what measures can be taken to slow or halt the degradation process. Transportation in the New Millennium 2 Other components of long-span bridges, existing and new, are being revolutionized as technology moves forward. Advances in deck technology are producing stronger, lighter decks. Orthotropic and exodermic decks are becoming increasingly popular on long-span structures as a means of reducing dead load. Bearings, joint systems, and seismic retrofitting components are becoming increasingly efficient as more large-scale testing facilities are built.在20世纪,桥梁施工技术,是由进化而来的 工业革命。随着新世纪的到来,钢桥受到铆接在一起,而不是 螺栓、混凝土桥梁被扔在的地方,不是预制、大型桥梁成员 从系酒吧和小的部分,不卷在一块。塑料尚未 发明了。制作等施工工艺、浆墙、土壤冻结, 加筋土墙尚未怀了孕。测量进行机械 自从红外、光学技术仍然是75年。 大桥建设是新千年开始转变。新建筑 技术和新材料正在浮出水面。也有新的解决面临的桥 建筑行业的相关研究的需要,这些新技术 材料。 大跨度桥梁 悬挂的桥梁 虽然悬索桥建设进行了整个20速度不快 世纪,前所未有的跨越了卓越的长度是建在记录 远东和丹麦。双方在日本明石海峡大桥正式通车,伟大的带桥 在丹麦是在一九九八年完成。这个明石海峡大桥正式通车是世界上最大的悬架 在这个世界上,与桥梁的m,1991年是中国的第二大带桥, 用一段1624)。 虽然已经增加了近5倍长度的跨世纪的过程中, 他们已经达到了他们的物理极限与今天的材料。研究将 必须发展新的、ultra-high-strength钢丝、碳纤维丝要求 建立了悬索,将不再主要可能增加到跨度的长度 超出2000米。 当我们进入新千年、康复和持续的维护现有的 悬索桥必须继续。最近的戒毒措施为主要 电缆悬架系统与这些桥梁发现退化 氢脆腐蚀,。研究还剩下的 寿命悬索桥电缆和什么措施可以减缓或 停止退化的过程。 在新千年的运输 其他组件的大跨度桥梁,现有的和新的,正在发生了革命性的变化 技术的进步。提出了在甲板上技术生产强的,更轻的 甲板。正交各向异性和exodermic牌是大跨度越来越受欢迎 作为一种手段,降低结构自重荷载。轴承、联合系统和抗震能力 越来越多的有效成分是更大规模的测试设备 建造。 50分！！~~谢谢 参考资料：我的大脑

A computer is a machine that manipulates data according to a list of first devices that resemble modern computers date to the mid-20th century (around 1940 - 1945), although the computer concept and various machines similar to computers existed earlier. Early electronic computers were the size of a large room, consuming as much power as several hundred modern personal computers.[1] Modern computers are based on tiny integrated circuits and are millions to billions of times more capable while occupying a fraction of the space.[2] Today, simple computers may be made small enough to fit into a wristwatch and be powered from a watch battery. Personal computers, in various forms, are icons of the Information Age and are what most people think of as "a computer"; however, the most common form of computer in use today is the embedded computer. Embedded computers are small, simple devices that are used to control other devices — for example, they may be found in machines ranging from fighter aircraft to industrial robots, digital cameras, and children's ability to store and execute lists of instructions called programs makes computers extremely versatile and distinguishes them from calculators. The Church–Turing thesis is a mathematical statement of this versatility: any computer with a certain minimum capability is, in principle, capable of performing the same tasks that any other computer can perform. Therefore, computers with capability and complexity ranging from that of a personal digital assistant to a supercomputer are all able to perform the same computational tasks given enough time and storage is difficult to identify any one device as the earliest computer, partly because the term "computer" has been subject to varying interpretations over time. Originally, the term "computer" referred to a person who performed numerical calculations (a human computer), often with the aid of a mechanical calculating history of the modern computer begins with two separate technologies - that of automated calculation and that of of early mechanical calculating devices included the abacus, the slide rule and arguably the astrolabe and the Antikythera mechanism (which dates from about 150-100 BC). The end of the Middle Ages saw a re-invigoration of European mathematics and engineering, and Wilhelm Schickard's 1623 device was the first of a number of mechanical calculators constructed by European engineers. However, none of those devices fit the modern definition of a computer because they could not be of Alexandria (c. 10 – 70 AD) built a mechanical theater which performed a play lasting 10 minutes and was operated by a complex system of ropes and drums that might be considered to be a means of deciding which parts of the mechanism performed which actions - and when.[3] This is the essence of programmability. In 1801, Joseph Marie Jacquard made an improvement to the textile loom that used a series of punched paper cards as a template to allow his loom to weave intricate patterns automatically. The resulting Jacquard loom was an important step in the development of computers because the use of punched cards to define woven patterns can be viewed as an early, albeit limited, form of was the fusion of automatic calculation with programmability that produced the first recognizable computers. In 1837, Charles Babbage was the first to conceptualize and design a fully programmable mechanical computer that he called "The Analytical Engine".[4] Due to limited finances, and an inability to resist tinkering with the design, Babbage never actually built his Analytical automated data processing of punched cards was performed for the . Census in 1890 by tabulating machines designed by Herman Hollerith and manufactured by the Computing Tabulating Recording Corporation, which later became IBM. By the end of the 19th century a number of technologies that would later prove useful in the realization of practical computers had begun to appear: the punched card, Boolean algebra, the vacuum tube (thermionic valve) and the the first half of the 20th century, many scientific computing needs were met by increasingly sophisticated analog computers, which used a direct mechanical or electrical model of the problem as a basis for computation. However, these were not programmable and generally lacked the versatility and accuracy of modern digital succession of steadily more powerful and flexible computing devices were constructed in the 1930s and 1940s, gradually adding the key features that are seen in modern computers. The use of digital electronics (largely invented by Claude Shannon in 1937) and more flexible programmability were vitally important steps, but defining one point along this road as "the first digital electronic computer" is difficult (Shannon 1940).
