what is undergroud railroad?什么是地下铁路？

道岔是一种使机车车辆从一股道道转入另一股道的线路连接设备，通常在车站站、编组站站大量铺设。有了道岔，可以充分发挥线路的通过能力。即使是单线铁路，铺设道岔，修筑一段大于列车长度的叉线，就可以对开列车。使列车由一组轨道转到另一组轨道上去的装置。 每一组道岔由转辙器(Railroad switch)、岔心、两根护轨和岔枕组成，由长柄以杠杆原理拨动两根活动轨道，使车辆轮缘依开通方向驶入预定进路。

不同的方法可以达到相同的目的

可以自动出现铁路图案设置。不用再画细节。

儿歌，“呜呜呜，火车开了，大家快上车”

您好。这句话的翻译是Railroad Develop History Roads of rails called Wagonways were being used in Germany as early as 1550. These primitive railed roads consisted of wooden rails over which horse-drawn wagons or carts moved with greater ease than over dirt roads. Wagonways were the beginnings of modern railroads. By 1776, iron had replaced the wood in the rails and wheels on the carts. Wagonways evolved into Tramways and spread though out Europe. Horses still provided all the pulling power. In 1789, Englishman, William Jessup designed the first wagons with flanged wheels. The flange was a groove that allowed the wheels to better grip the rail, this was an important design that carried over to later locomotives. The invention of the steam engine was critical to the invention of the modern railroad and trains. In 1803, a man named Samuel Homfray decided to fund the development of a steam-powered vehicle to replace the horse-drawn carts on the tramways. Richard Trevithick (1771-1833) built that vehicle, the first steam engine tramway locomotive. On February 22, 1804, the locomotive hauled a load of 10 tons of iron, 70 men and five extra wagons the 9 miles between the ironworks at Pen-y-Darron in the town of Merthyr Tydfil, Wales to the bottom of the valley called Abercynnon. It took about two hours. In 1821, Englishman, Julius Griffiths was the first person to patent a passenger road locomotive. In September, 1825, the Stockton & Darlington Railroad Company began as the first railroad to carry both goods and passengers on regular schedules using locomotives designed by English inventor, George Stephenson. Stephenson"s locomotive pulled six loaded coal cars and 21 passenger cars with 450 passengers over 9 miles in about one hour.

Jeme Tien Yow (April 26, 1861 u2013 April 24, 1919) was a distinguished Chinese railroad engineer. He was educated in the United States of America and was the Chief Engineer responsible for construction of the Imperial Peking-Kalgan Railway, the first railway constructed in China without foreign assistance. He was also said to be an advisor of the construction of the Kowloon-Canton Railway, for the Lo Wu Bridge built in 1906. A museum was also established nearby to commmerorate the works of Jeme Tien Yow.

　　托福口语练习需要了解什么？这是每一个正在备考托福口语的同学都需要了解的，那么下面就和一起来看看练习托福口语要注意哪些问题？ 　　练习技巧 　 　1.精准词汇的控制 　　在托福口语中，究竟需要拥有多少词汇才能开始精彩的文章表述？其实，对于这一词汇量没有具体的数量，一般来说2500左右。但是，需要我们了解的就是，如果在口语表述中能成功使用一些动词、连词、俚语等等，则能更加突出口语的精彩的口语表达感觉。 　 　2.简单句和复合句的配合 　　在托福口语表达中，不讲究太多的语法内容，主要是简洁明了的表达清楚自己的观念和内容。换而言之，也就是在口语表达中，只要保证自己语法的正确，尽量学会短句多、长句少这样的配合方式即可。同时，智课网建议大家如果能添加一些俚语的使用就更加完美。 　　3.经典五要素的使用 　　在口语表达内容中，西方人不是过于讲究文字的修饰，而更加讲求真实。所以，对于谁，在什么时间什么地点做了什么事情，理由是什么？在内容中有严格的要求，也就是WHO WHAT WHY WHERE HOW这五大要素。只有在文章拥有了这五大要素才能拥有一段逻辑严密的口语内容。 　 　4.口语的不断练习 　　口语难度系数 　　 1.细节变得更多： 　　特别是Task3这种校园话题，在conversation中，男生和女生闲聊的内容会更多些，personal information就会变得更多，记笔记的时候就会更忙。 　　 2.笔记制胜 　　平时练习的时候大家可能没有感觉，但是到了考场就会有一种突如其来的孤独感：文本，听力原文什么都没有，只有笔记和自己相依为命。 　　所以笔记是非常非常重要的。 　 　3.不同task的focus： 　　Task3： 细节 　　Task4： 故事主干 　　Task5： 个人原因阐述 　　Task6： 两个例子的完整性 　　在记笔记的时候，每一个task的侧重点都会有不同，请同学们一定注意。 　　尤其是task6，切忌狂记，一定要有选择性的去记笔记。 　　这个是2015年6月份的一道考题 　　题目 　　Using the examples from the lecture， explain two ways the railroad system changed business in the United States. 　　部分原文： 　　Ok， so we"ve been talking about various factors that have changed the United States" economy. One especially important factor is the development of railroads. When the railroad system expended to almost the US， it fundamentally changed the way business perform in this country. 　　For one thing， it expanded and the railroad enable companies to start selling their goods to all of the country. Since trains could now transport merchandise all over US， companies could now sell good to customers pretty much anywhere of the country. 　　For example. There was a big company that sold quartz. The company started in a big city. And before the development of railroad， the company could only sell its quartz to people living in or near the city. But when the railroad expanded， the company could load their quartz on trains and have it delivered to all parts of the country. 　　第一段有没有同学很想不由自主记笔记的？但是你记完了就会发现：没有任何用！因为第一段是背景知识的交代和细节阐示。所以第一段基本上：不用记！ 　　那从哪里开始？第二段！因为从第二段开始，professor才开始详细讲述railroad给美国经济带来的实际性的好处，所以，第二段才有关键信息涵盖在内。

Jeme Tien Yow ( 1861-1919 )Jeme was born in Guangzhou,Guangdong province. In 1872, twelve-years-old Jeme was sent to the United States for education. After studying at a primary school in New Haven, he then entered a secondary school there, and in 1878, Jeme was admitted to Yale University. Jeme"s major was Civil Engineering, with an emphasis in railroad construction. Jeme received his bachelor"s degree in 1881, and then he was recalled back by the Imperial Qing government.Then Jeme was sent to the newly formed Imperial Navy in Fuchow, Fujian Province. A few years later, he finally found his way to become a railroad engineer. In 1905, the Imperial Qing government decided to build a railroad that would link the capital of Peking to the important trade city of Kalgan to the north. This railway would be of strategic importance to the Imperial government. A decision was therefore made that the railway would be built without foreign assistance. Capital would come from the government, and no foreign engineers were to be hired. Jeme was appointed as Chief Engineer of the railway. At the beginning, some people were skeptical that the Qing government would be able to construct the railroad in the rugged mountains North of Peking all by itself. But Jeme showed he was an able engineer and completed the work two years ahead of schedule and under budget. He designed a zig zag upwards railway by switching back the line near the Qinglongqiao railway station to overcome the steep gradient. Jeme was also responsible for setting many railroad standards that are still in force in China today. He was also the founding member of the China Institute of Engineers. Jeme was awarded an honorary doctorate degree by the University of Hong Kong in 1916. For his contributions to railroad engineering in China, Jeme was often called the Father of China"s Railroad. Jeme died in Hankou in 1919 at the age of 58. He was buried at the Qinglongqiao railway station. A museum was also established nearby to commmerorate the works of Jeme Tien.

交通运输专业学什么，就业方向怎么样？其实我觉得交通运输专业还是一个非常不错的专业，因为现在高考填报志愿已经结束了，有很多学生已经填报了志愿，而且收到了学校的录取通知书，但是大家有很多人对自己的专业并不是太了解，特别是像交通运输专业这样的专业。很多人不知道到底是学的是什么。可以很负责的告诉大家，交通运输专业其实是和交通相关的，而且它的基本知识就是交通加上运输这两门专业课是最主要的。而且具体的分类也有很多，比如有铁路交通有公路交通有航空等等。这些具体的分类在本科期间应该是不会分的太具体，特别是有些专业划分的比较泛泛，所以在这种情况之下，基本上不会分的太具体，应该是都要学的。嗯，如果要是考研究生的话或者是考博士的话，可能在以后的学习生活中会分的比较具体，以后从事什么样的专业，从什么样的方向就会比较清晰了。但是现在来看，这种情况划分还是不是太明确的，如果要是大家对这个方向感兴趣的话，可以填报这个专业。这个专业以后从事的主要方向就是和运输相关的，应该是在铁路运输管理部门，或者是公路运输，航空运输等各方面都有可能涉及，而且就业面比较广泛，相比于普通的一般专业来说，这种专业的对专业的要求性更高一些。在以后的工作中可能更加深入的了解，但是刚毕业的时候可能对这个行业并不是太深入，所以以后慢慢摸索中会有进步。

如果我没记错的话这是美国经济大萧条时期民间流行的歌曲。(历史书上看过……)但是胡佛政府对美国经济的放任政策，使美国百姓很穷困，无数的人失业。这首歌就是在那样的背景下创作的。要说含义…………就是反应了当时美国人民的穷困与悲凉，和对当时政府的不满只找到了英文歌词Brother Can You Spare A Dimeonce I built a railroad, made it runmade it race against timeonce I built a rairoad, now it"s donebrother can you spare a dime?once I built a tower to the sunbrick and rivet and limeonce I built a tower, now it"s donebrother can you spare a dime?once in khaki suitsgee, we looked swellfull of that yankee Doodle De Dumhalf a million boots went slogging through hellI was the kid with the drumsay don"t you remember, they called me AlIt was Al all the timesay don"t you remember, I"m your pal!buddy can you spare a dime?once I built a railroad, made it runmade it race against timeonce I built a rairoad, now it"s donebrother can you spare a dime?once I built a tower to the sunbrick and rivet and limeonce I built a tower, now it"s donebrother can you spare a dime?once in khaki suitsgee, we looked swellfull of that yankee Doodle De Dumhalf a million boots went slogging through hellI was the kid with the drumsay don"t you remember, they called me AlIt was Al all the timesay don"t you remember, I"m your pal!buddy can you spare a dime?

磁卡的原理 记录原理记录磁头由内有空隙的环形铁芯和绕在铁芯上的线圈构成。磁卡是由一定材料的片基和均匀地涂布在片基上面的微粒磁性材料制成的。在记录时，磁卡的磁性面以一定的速度移动，或记录磁头以一定的速度移动，并分别和记录磁头的空隙或磁性面相接触。磁头的线圈一旦通上电流，空隙处就产生与电流成比例的磁场，于是磁卡与空隙接触部分的磁性体就被磁化。如果记录信号电流随时间而变化，则当磁卡上的磁性体通过空隙时（因为磁卡或磁头是移动的），便随着电流的变化而不同程度地被磁化。磁卡被磁化之后，离开空隙的磁卡磁性层就留下相应于电流变化的剩磁。如果电流信号（或者说磁场强度）按正弦规律变化，那么磁卡上的剩余磁通也同样按正弦规律变化。当电流为正时，就引起一个从左到右（从 N 到 S）的磁极性；当电流反向时，磁极性也跟着反向。其最后结果可以看作磁卡上从 N 到 S 再返回到 N 的一个波长，也可以看作是同极性相接的两块磁棒。这是在某种程度上简化的结果，然而，必须记住的是，剩磁 Br 是按正弦变化的。当信号电流最大时，纵向磁通密度也达到最大。记录信号就以正弦变化的剩磁形式记录，贮存在磁卡上。工作原理磁卡上面剩余磁感应强度Br 在磁卡工作过程中起着决定性的作用。磁卡以一定的速度通过装有线圈的工作磁头，磁卡的的外部磁力线切割线圈，在线圈中产生感应电动势，从而传输了被记录的信号。当然，也要求在磁卡工作中被记录信号有较宽的频率响应、较小的失真和较高的输出电平。一根很细的金属直线可以作为一个简单的重放设备。金属直线与磁卡紧贴，方向垂直于磁卡运行方向，磁卡运行时，金属直线切割磁力线而产生感应电动势，电动势的大小与切割的磁力线成正比。当磁卡的运行速度保持不变时，金属直线的感应电动势与磁卡表面剩余磁感应强度成正比，而导体中的感应电动势可由下式表示：e=BrWv 式中 Br －表面剩余磁感应强度；W －记录道迹的宽度；v －重放时磁卡的运行速度。在 Br=2πf/vφrmcos2πft 的情况下，综合 Br 和 e 的关系式，得到 e=2πfWφrmcos2πft 。 当然，用一根金属线作磁卡工作设备，由于输出很小，故而是不实用的。而磁头是用高导磁系数的软磁材料制成的铁芯，上面缠有绕组线圈，磁头前面有一条很窄的缝隙，这时进入工作磁头的磁卡磁通量而言，可以看作是两个并联的有效磁阻，即空隙的磁阻和磁头铁芯的磁阻。因为空隙的有效磁阻远大于工作磁头铁芯的磁阻，所以磁卡上磁通量的绝大部分输入到磁头铁芯，并与工作磁头上线圈绕组发生交连，因而感应出电动势，在这种情况下，单根金属重放线所得到的感应电动势公式完全适用于环形磁卡工作磁头，只是比例系数不同而已。设 N 为线圈的匝数， m 为与工作磁头铁芯的大小和磁性有关的系数，则环形工作磁头绕组中所产生的感应电动势为：e=2πfWmNφrmcos2πft因为在工作磁绕组中所感应的电动势正比于磁通的变化率，即电动势 e ∝ By ∝ 频率 f 。在记录时 i=Isinwt ，纵向剩磁密度 Bx ∝ i （传递曲线的直线部分），所以， Bx=K1Isinwt 。由于 By ∝ dbx/dt,e ∝ By ，所以， e=K2Iwcoswt 。这里的 K2 取决于工作磁头的效率、匝数、磁带材料等。这些公式还表明：输出电压正比记录电流；输出电压正比于信号频率；输出电压得到 90°的相应变化（即由正弦项改变到余弦项）。

　　胶片相机使用银盐(主要是溴化银AgBr)感光材料附着在塑料片上(即胶卷)作为载体，拍摄后的胶卷要经过冲洗才能得到照片，在拍摄过程中也无法知道拍摄效果的好坏，而且不能对拍摄照片进行删除。　　每种胶片（包括彩色胶片）都包括两个基本组成部分：一个单层的或多层的感光乳剂层、一个感光乳剂层的支持体——片基。乳剂是由对光敏感的微细颗粒悬浮在明胶介质中而成。胶片上的明胶与某些食品所用明胶类似。　　在明胶中悬浮着的光敏物质是卤化银颗粒。这种颗粒如此微细，只有在高倍显微镜下才能观察到。在1平方英寸通常的感光胶片乳剂中，卤化银晶体的含量约达400亿个之多　　卤化银晶体具有一经曝光其结构就发生变化的特性。这一化学性能变化的机理对我们并非重要，其变化的终结效果才是最重要的。这一变化是怎样产生的呢？当你拍摄时，光线通过相机的镜头射到胶片的乳剂层上，当光线到达卤化银晶体时 这种因卤化银晶体聚结而形成的团块仍然是极其微细的。乳剂层接受到的光量愈 晶体的变化和聚结。这就是说不同强度的光照射到胶片上，胶片乳剂层的微观领域就有不同数量的晶体发生结构变化和相互聚结.　　胶片一经曝光，立即产生潜影——一种看不见的影像。必须将胶片进行显影操作才能使潜影转化为可见的牢固影像。当胶片显影，结构已发生变化的卤化银晶体便转化为黑色金属银颗粒的聚结体，从而产生影像——负像。胶片上那些没有感光的，也就是没有发生结构变化的晶体即被一种称作定影剂的化学品洗去，使这些部分呈现浅灰或透明。结果是负像上黑暗（厚的）部分就是曝光较多部分；明亮（薄的）部分就是曝光较少部分；全透明部分就是没有受到光照射的部分。这就是黑白胶片记录影像的基本过程。　　彩色胶片有三层感光乳剂层，在这些乳剂层里还分别含有不同的能够生成染料的有机化合物，叫做彩色偶合剂（成色剂）。它们本身是无色的，但在彩色显影时能与彩色显影剂的氧化物耦合成为有色的染料。对于负性胶片，上层盲色乳剂里所含的偶合剂在彩色显影时形成黄色，中层形成品红色，下层形成青色，这就是我们得到的经过冲洗的彩色胶片。通过扩印或放大再把影像投射到照相纸上或者是反转片的反转冲洗，胶片上层的黄色转变为它的补色蓝色，中间一层转为绿色，下层则转为红色，我们就得到了与自然状态一样的彩色照片或者透明的反转片。这就是彩色胶片记录影像的基本过程。

实像和虚像的区别如下：1、成像原理不同，物体发出的光线经光学器件会聚而成的像为实像，经光学器件后光线发散，反向延长相交形成的像叫虚像。2、成像性质上的区别，实像是倒立的，虚像是正立的。3、接收方法上的区别：实像既能被眼睛看到，又能被光屏接绝键收到，虚像只能被眼睛看到，不能被光屏接收到。举例说明实像的例子：小孔照相机底片上的像、眼睛视网膜上的像、团猛电影银幕上的像、投影仪银幕上的像、照相机底片上的像。虚像的例子：放大镜下看到的放大的字、水里的并或巧“物体”、照镜子时看到的像、海市蜃楼现象、闪烁的星星。
