The thesis contains five chapters. The first chapter summarizes the development and research of switched reluctance drive, discusses the main research direction, and explains the main work in this paper. In chapter 2, hardware system which includes the design of power converter and various control circuit is discussed. TMS320LF2407 DSP is used to design the hardware circuits of SRM control system, and design details including the current detection, position sensing, fault protection, speed detecting, keyboard and display etc. are provided. Because of the full use of the abundant peripheral resources of DSP, it comes to the aim simplifying the circuit structure and heightening the reliability. In chapter 3, the application of neural network on SRM control system is introduced, a new the application of neural network and the method of sampling is proposed and a simulation system based on Matlab/Simulink is established. Chapter 4 discusses the routine designing issue. Because the modularized programming method is adopted, and multi-interrupt processing technique is used, operation efficiency of the control software is highly raised. At last, the foregoing SRM control system is tested. Speed adjustment is realized, and other targets on the research and design of SRM control system are reached, which establishes a good foundation for further research.

本文共分五章，第一章概述了开关磁阻电机调速系统(Switched Reluctance Drive，简称SRD)及其发展和研究现状，论述了其主要研究方向，并说明了本文的主要工作；接下来的一章主要讨论了SRM的硬件系统，主要包括功率变换器的设计和各种控制电路的设计，本文以TMS320LF2407为核心设计了开关磁阻电机控制系统硬件电路，给出了包括电流检测、位置检测、故障保护、测速电路及键盘和显示电路等部分电路的详细设计，充分利用了DSP的丰富外设资源，达到了简化电路结构、提高运行可靠性的目的；第三章介绍了人工神经网络在开关磁阻电机控制系统中的应用，提出了一种新的应用方式(利用GPFN神经网络调节PI参数)以及如何采取样本，搭建了基于Matlab/Simulink的仿真系统；在第四章中，讨论了开关磁阻电机控制软件的设计，采用模块化编程方法，采用基于多中断的控制程序，提高了控制软件的效率；最后，对所设计的开关磁阻电机控制系统进行了实验，实现了电机调速，达到了开关磁阻电机控制系统研究和设计的预期目标，为更近一步研究打下了基础。

Obviously, a single member booting all the others is seldom a good thing.: I can't think of a legitimate reason for doing so. But let's look at a real-life issue and compare: If the Lion's Club or the Kiwanis had a local unit president who booted all the members, would the police get involved? Would a lawyer accept the case? Would the members be able to ask for a refund of their dues or compensation for their time invested in the club?

朋友，看起来我们差不多呀，都给无辜封号了，我都写了很多信，从GM's replay来看，个人判断那些人估计是直接看都没看，对我们中国玩家直接"无视"，说句实话，我知道的一些封号的理由，在国内直接是闻所未闻，这GM要是国内，不被人打死也被人骂死。

For the crowd: a motorcycle opened, Zhu Dongju, electric vehicle speed, the wind will come in, really can not stand the cold, this kneepad, taking into account the special issue, the longer kneepad, and to build a covered shoes, At the same time, also extended into the knee of the above, the effect of wind improved.

适合人群：开摩托车、助动车、电动车速度较快时，寒风会进来，冷得真是受不了，这款护膝特意考虑到了这个问题，把护膝加长，并盖到了鞋盖上，同时也加长了到膝盖的上面，挡风效果明显提高。

Within the DPJ, despair at Messrs Hatoyama and Ozawa is growing. On April 7th Kozo Watanabe, an influential DPJ rebel, went so far as to suggest that Mr Hatoyama's cabinet should resign en masse if it fails by next month to resolve a fractious issue concerning the relocation of an American marine base in Okinawa, an island in southern Japan.

在民主党内部，越来越多的人对鸠山由纪夫和小泽一郎感到失望。4月7号，颇具影响力的前民主党议员渡部恒三甚至建议如果下个月没能解决好关于在日本南部Okinawa岛重建美国海军基地的琐碎问题，首相鸠山由纪夫就应该解散其内阁。

此外，该镇还千方百计盘活存量资产，将安西村的村小学存量资产租给内江老板投资900万元，办起了曲酒厂，不仅每年可纳税10万元，还可解决上百人的就业问题；同时引进了民生食品泡菜加工企业，依托龙头，实行"公司+农户+产业"工人的模式，打造成都市最大的泡菜生产企业，预计10月底投产后，可解决800人的务工问题。

In general, this issue belongs to the category of environmental history. While when it comes to some specific issues, trace element in soil is the cut-in point to study the changes of Chinese ancient society. At the present time, such research method hasn\'t been applied in history studies domestic and abroad so far. Therefore, the studies of the paper are only exploratory and immature researches.Three issues are concerned here:lTrace element in soil under geographical environment and the Hun and the Hsienpei\'s levirate.

本文主要探讨地理环境下的土壤微量元素与中国古代社会变迁的关系问题；在总体上，这一专题是属于环境史的范畴；但在具体问题上，则是以地理环境下的土壤微量元素问题做为切入点，来研究中国古代社会变迁问题的；就目前的情况看，这种研究方法在国内外历史学的研究中尚无先例；所以，本文的相关研究只能是带有一些探索性的、不成熟的研究。
