Firstly, this thesis makes an introduces on the developement of PMSM servo system based on DSP. According to the control theory of AC PMSM servo system, this paper analyzes the coordinate transformation, the rotor magnetic field orientation and the current control strategy of AC servo system. The control strategy is i_d=0. The system is orientates towards rotor magnetic field. Then the mathmatic models of PMSM in d-q coordinate are set up.

本文首先对基于DSP的永磁同步电机伺服系统的发展概况进行了介绍；根据永磁同步交流伺服系统的基本控制理论，分析了交流伺服系统坐标变换原理、常用的磁场定向方式及电流控制策略，并给出i_d=0电流控制策略及永磁同步电机按转子磁场定向的控制方式，从而建立永磁同步电机d-q坐标系下的数学模型。

Analyzing in a general view and studying systematically guide theories, basic processes and means of figure re-creation in literature interpretation, the thesis illustrates with the Chinese rendering A Storey Of Building written by Jia Yimu, and demonstrates that a rendering with both social and aesthetic values should proceed from thought exchange, basis on the practice of acceptants, aim at interpreting of artistic re-creation and dedicate to the national cultures and cultural exchange.

论文从宏观角度出发，以甲乙木汉译本《一层楼》为范例，试图通过对文学翻译中艺术形象再塑的基本指导原则和要求、基本过程、基本方法做一比较全面和系统的分析和探讨，论述了艺术形象再塑这一文学翻译中普遍性问题的重要性，论证了只有从思想交流的实际出发、以读者的接受实践为依据、着眼于艺术再现的翻译，才能够造就既具社会价值、又具美学价值的译作珍品，从而达到为各民族文学与文化交流做贡献的最终目的。

The first is Qin culture's value in the market economy, from the perspective of modem mining, the essence of the inherent humanity, addressing its deep flaws and reshape its modem value, The second is Qin cultural circle and coordinated regional economic development, Qin cultural circles and the big-Guanzhong mark sphere has the inherent linds, Qin culture research should be based on reality, from the perpective of cultural capital build a solid foundation for culture; The third is Qin culture's industrialization, which has an advantage in location and resource advantages; The fourth is inter-regional cultural cooperation's issues, Qin cultural studies should be carried out in the wide-area, multi-perspective of a comprehensive study; The fifth is to introduce the new paradigm issues. such as cultural capital, social capital and human resources.

一是秦文化在市场经济中的价值挖掘与重塑问题，应从现代性角度挖掘秦文化的内在人文精髓，正视其深层中的秦文化圈与区域经济视域下的大关中经济圈具有内在契合性；秦文化的相关研究应该立足于大关中经济圈的现实，从文化资本角度为大关中经济的腾飞打造坚实的文化根基；三是秦文化自身的产业化问题，秦文化圈具有文化产业的区位优势和资源优势，应从经济与文化交叉的角度深入作域文化产业发展模式问题；四是区域间跨文化经济交流合作问题，秦文化研究应在跨省际、跨区域的横向文化交流合作中对其内在关系进行宽领域、多视角的全面研究；五是在研究中引人新范式问题，应有效借鉴文化资本、社会资本、人力资源、企业文化与企业家精神等一些新的分析范式，推动相关研究的深人拓展。

On the one hand the Orientalist consciously or unconsciously attempts to control and manipulate the process of dialogue and communication, on the other hand they are frustrated again and again because they meet the elastic resistance of the sophisticated and wise India civilization. As a result, the contact and the communication between the West and the East were spoiled, suspended and even aborted, making both sides frustrated and upset.

通过条分缕析的文本分析，暴露在这个过程中作为政治霸权与文化霸权的殖民者，一方面对双方之间的对话与交流进行有意无意的策划、操纵；一方面他们的操纵过程又因为受到古老印度文明的&软性&抵抗而不断受到挫折，因此使这些接触、交流和试图进行的所谓&东方&与&西方&的&联结&或被&悬置&或被破坏，其结果只能以不愉快甚至于导致冲突而告终。
