Question

请英语高手帮我翻译一下我的论文摘要，不要机器翻译的

在本论文写作过程中，我考虑了多种设计方案及技术。结合课题（小型系统）要求，最后我选择了采用纯数字电路。在电路的设计过程中，经过多次修改及使用Multisim仿真，最终确定了设计方案。
此交通控制器主要结构为：时钟电路，时序控制电路，倒计时显示电路，15秒控制电路。
此系统使用的主要技术是：时序逻辑电路技术。从总体上看，时序电路由组合电路和存储电路两部分组成。任一时刻的输出信号不仅与当时的输入信号有关，而且还与电路原来的状态有关。
设计时序电路控制红绿灯时，一开始设定了八个状态：1、火车由西向东未压上x1；2、由西向东压上x1；3、由西向东位于x1和x2之间；4、由西向东压上x2；5、火车由东向西未压上x2；6、由东向西压上x2；7、由东向西位于x2和x1之间；8、由东向西压上x1。不能实现红绿灯的转换。解决方案：将1状态和5状态合并为“火车位于x1和x2之外”。

Answer 1

In this thesis writing process, I consider a variety of design and technology. Combination of subjects (small system), which ultimately I chose to adopt a purely digital circuit. At the circuit design process, through a series of modifications and the use of Multisim simulation, finally identified the design.
This traffic signal controllers for the main structure: the clock circuitry, timing control circuit, the countdown display circuit, control circuit 15 seconds.
This system uses the main techniques are: sequential logic circuit technology. Overall, the sequential circuit by combinational circuits and storage circuits composed of two parts. At any one time not only with the output signal of the input signal at the time, but also with the circuit related to the original status.
Design of sequential circuits to control the traffic lights, one set of eight start status: 1, train from west to east is not pressure on x1; 2, from west to east pressure on x1; 3, from west to east is located between x1 and x2; 4, from west to east pressure on x2; 5, train from east to west is not pressure on x2; 6, from east to west pressure on x2; 7, from east to west is located between x2 and x1; 8, from east to west pressure on x1. Conversion of traffic lights can not be achieved. Solution: The 5 status 1 status and be merged into the "train is located outside of x1 and x2."

专业术语太多啦，自己可以先去查查，或者自己写出来，让我等给你改改。
