II. Briefly answer the following questions (20%).
1.Mor Code is also called as wireless telegraphy. It was invented by Guglielmo Marconi in 1895. 纸制品Some people believe that the Mor Code is the earliest broadcasting communicating signal ud in the train.
2.Signals have two purpos, protection and control. There are two types of signals, permissive and absolute. You can tell if a signal is permissive or absolute by looking at it. Permissive signals only provide protection. Absolute signals provide both control and protection. Functionally, the basic difference between permissive and absolute signals is the most restrictive type of indication each can display. 微信3
3.The Chine Train Control System is a train control system ud on railway lines in People's Republic of China. CTCS is similar to the European Train Control System (ETC
S). It has two subsystems: ground subsystem and onboard subsystem. The ground subsystem may bad on bali, track circuit, radio communication network (GSM-R), and Radio Block Center (RBC). The onboard subsystem includes onboard computer and communication module.
4.ATP can also refer to automatic train protection systems in general, as implemented in other parts of Europe and elwhere. Automatic Train Protection (ATP) means either of two implementations of a train protection system installed in some trains in order to help prevent collisions through a driver's failure to obrve a signal or speed restriction.
5.There are many kinds of railroad vehicles, and trains are only one of the kinds. High-speed rails, monorails, light rails, maglev trains and metros are all railroad vehicles花间美人.
IV. Translate the following text into Chine (20%).
1.火车是铁路运输的一系列的车辆，通常沿一个轨道运输货物或乘客。由分离的机车或在自推进多个单位中的单个电动机提供动力。虽然历史上蒸汽推进曾居于主导，但最常见的
现代形式是柴油和电力机车，后者通过架空导线或附加轨提供动力。其它能源包括马、发动机或水驱动绳或金属丝绞盘、重力、气动、电池和燃气轮机。火车轨道通常由两个运行轨道组成，有时由附加轨补充，诸如电动导电导轨和架导轨，以及数量有限混合单轨和磁悬浮导轨。
2.理解铁路路旁的信号不是简单地理解为“绿灯行，红灯停。”为了理解轨道沿线的信号告诉你的信息，你首先必须掌握一些基本的概念。铁路交通管制归结为三种情况：在同一个轨道上的相同的方向上运行的列车;列车在同一轨道上沿相反的方向运行;和相交两个轨道运行列车。
V. Answer the following questions in details(20%)卫生室.
1. Illustrate the components of a rail system.
Answer:
Railroad systems are complicated, mainly consisting of nine parts, and they are electrical circuits, railway tracks, railway stations, electricity supply, communications, signals, vehicl
es, railway control, and maintenance.
Electrical circuits supply electric power to railway trains, metros, trams and so on. However, as the development of science and technology, a variety of electrification systems have appeared in the railway running.
柳公权玄秘塔碑字帖Railway tracks and stations refer to the outside and ground constructions of railways. The construction of railway tracks and stations is often difficult and contains hard work, which also includes the design of the construction and the laying of the electrical circuits.
