摘要:基于通信技术的列车运行控制系统(CBTC)是铁路信号的发展方向，交频分复用
OFDM)是一种无线环境下的高速传输技术，它对高速列车控制信息传输中卞要受到的由于多
径传播引起的快衰落所产生的影响有很强的抵抗能力.本文首先介绍了OFDM技术的发展和
基本原理，然后在计算机上用M atlal〕对其性能进行了仿真，仿真中将OFDM与传统的单载波
调制方式―i1，交振幅调制( 1frQAM)对抗多径十扰的性能进行了比较，最后分析了一者的仿真结果.

单端反激式开关电源具有结构简单、输入输出电气隔离、电压升／降范围宽、易于多路输出、可靠性高、造价低等优点，广泛应用于小功率场合。然而，由于漏感影响，反激变换器功率开关管关断时将引起电压尖峰，必须用钳位电路加以抑制。由于RCD钳位电路比有源钳位电路更简洁且易实现，因而在小功率变换场合RCD钳位更有实用价值。 -Single-ended flyback switching power supply with a simple structure, input and output electrical isolation, voltage up/down range, easy to multi-output, high reliability and low cost, widely used in low-power occasions. However, due to leakage effects flyback converter power switch off when the voltage spike caused by the need to be inhibited by clamping circuit. RCD clamp circuit as a result of active-clamp circuit than the more concise and easy to realize, and in low-power transform RCD clamp occasions more practical value.

太原理工大学硕 士 学 位 论 文 摘 要 派送调度问题是物流管理领域中一个重要的课题，是大型 超市集团、大型零售连锁店、物流派送中心及工业生产企业共 同存在的问题。随着跨地区、跨地域的经济活动日益加强，迫 切要求解决物资流通当中合理调度运输工具的问题来有效实现 企业生产计划、减少物资库存，从而提高工商企业的生产效率。 目前对于派送调度问题的研究主要集中在对运输工具的配置和 静态调度领域，这些研究工作已经取得了丰富的成果，并且研 究结果也主要应用于决策和管理方面。但是对于运输工具运行 情况变化和派送任务动态产生和调整关注较少，同时，在线派 送调度的计算机系统产品也较少-Taiyuan University of Technology master"s degree thesis Abstract delivery scheduling problem is the logistics management field an important issue, is a large supermarket groups, large retail chains, logistics distribution centers and industrial production enterprises to the problems that exist. With trans-regional and cross-boundary economic activities increasing, it is urgent to address the flow of goods among them reasonable means of scheduling problems to the effective realization of production plans to reduce material inventory, thereby improving business productivity. Current scheduling problems for the delivery of concentrated mainly in the transport and distribution of static scheduling field
