There are many serious misleading in how to apply the principle of "fraud exception", whereas, it is necessary to make a legal research on the principle of "fraud exception" in light of former researches. The article consists of two parts. In the first part, the author put emphasis on the principle of abstract independence, the definition, the establishment and development of the principle of fraud exception, the analysis of the fraud, the theory, the prerequisite and the procedure of apply the principle of "fraud exception" in order to establish the general principle and necessary procedure. In the second part, the author analysis the existing backward conditions oflegislation and judicial practice in China, and courts" attitude to the judicial remedy for the principle of " fraud exception", further, the author puts forward some suggestions on how to make the legislation on the principle of "fraud exception" perfect, and how to apply the procedure of judicial remedy for the principle of "fraud exception". Lastly, the author hopes that these suggestions could benefit to the judicial practice and the future legislation on the principle of "fraud exception.

我国在加入世界贸易组织后，按照国际惯例和国际公约处理国际贸易中的纠纷己成为一种必然趋势，鉴于我国法院对如何准确适用信用证欺诈例外原则存在着严重误区，使得在先前学者研究的基础上再一次研究欺诈例外原则很有必要，本文分两个部分，第一部分对信用证独立抽象原则、信用证欺诈例外原则的定义、确立与发展、对例外原则下欺诈的分析、理论基础、适用条件以及程序等六方面展开论述，从而确立信用证欺诈例外原则的一般原则和必要的程序：第二部分主要分析我国司法实践中信用证欺诈例外原则司法救济的立法以及司法现状，及法院对欺诈例外原则的态度，从而对如何完善我国法院欺诈例外原则的法律依据以及如何正确适用欺诈例外原则的司法救济程序提出一些构思，希望为欺诈例外原则在我国的司法实践以及为以后的相应立法提供有益的参考。

The research work of this article is made up of theory and application, it includes three partsrthe first, it takes SWOT analytical technology to analyse Zhangjiagang port" s developing strategic enviorment . The second, it according to the statistical figures about the cargo transport in recent years, it analyzes cargo transport structure and the changing law and the internal reason of cargo transport. At the same time it analyzes and calculates the change of the arriving ships" structure for a systematic and full understand of the transport demands. The third, it make a scientific forecast of the port" s future cargo capacity making use of the grey forecast system, which provides scientific basis for medium-long term development plan of the port"s cargo handling capacity. It also makes some analysis and research for medium-long term development future of Zhangjiagang port in use of physical unit analising technique, looks for the scaltered no-order and no-system reason of medium-long term development.

The article presents the developing condition of PWM and SVPWM first.Then the theory of SVPWM is discussed in detail.The SVPWM is based on the thought of magnetic chain tracking.It makes the ideal magnetic chain circle of three-phased sysmmetry electric motor supplied by three-phased sysmmetry sine wave voltage for basis,uses the practical magnetic chain vector formed by the different switch modes of three-phased inverter to track the basic magnetic chain circle.During the course of tracking,the inverter changes the switch modes properly to form the PWM waves.Then the modulation wave of SVPWM is analyzed in detail.The modulation wave of SVPWM is implicit,but the analogous modulation wave in A-B-C axis needs to be calculated in order to expose the internal relation of SVPWM and SPWM.That is to show the implicit modulation wave of SVPWM. SVPWM actually is a transformed SPWM ruly sampled by the modulation wave which is injected by the zero prefaces based on space vectors.

本文首先对脉宽调制技术的发展现状进行了综述，在此基础上分析了电压空间矢量脉宽调制技术的发展现状；接着对空间电压矢量脉宽调制技术的基本原理进行了详细的分析和推导，SVPWM是基于磁链追踪的思想，它以三相对称正弦波电压供电下三相对称电动机定子理想磁链圆为基准，由三相逆变器不同开关模式下所形成的实际磁链矢量来追踪基准磁链圆的，在追踪的过程中，逆变器的开关模式作适当的切换，从而形成PWM波；然后详细分析了电压空间矢量脉宽调制技术的调制波，虽然SVPWM法的调制波是隐含的，但是为了揭示SVPWM法与SPWM法的内在联系，需要求出SVPWM在A-B-C坐标系上的等效调制波，也就是将SVPWM的隐含调制波显化；SVPWM实质是一种基于空间矢量在三相正弦波中注入了零序分量的调制波进行规则采样的一种变形SPWM。

Chapter 1 starts with the discussion of trade and investment. First, it explains that the expansion of the scope and jurisdiction of WTO is a self-completion in order to meet the requirement of the development of economic globalization. The problem of investment is put forward as part of economic globalization. So the question why investment problem is brought forward is settled in theory.

论文的第一章从GATT和WTO关于贸易和投资的讨论出发，首先阐明了世界贸易体制范围和管辖权的扩大是WTO为了适应经济全球化发展的内在要求而进行的一种自我完善；而投资问题正是作为经济全球化的一部分而提出的，因而从理论上解决了为什么要提出投资政策的问题。

At first, its influence was mainly in philosophy and literary criticism. After 1970"s, some architects attempted to apply its theory in the architecture in order to break the traditional thought. In the 80"s, deconstructionist architect Bernard Tschumi applied it to the park creation--La Villette Park that was the only deconstructionist park form in the world.

最初，它的影响主要在哲学和文学批评领域。70年代以后，一些先锋派建筑设计师试图将其理论应用于建筑设计中，以突破传统建筑设计思想。80年代，解构主义建筑师屈米又将其应用于公园的创造中，形成了目前世界上唯一的解构主义园林——巴黎拉维莱特公园。

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.

索夫农 、森那库斯和苏格拉底式的对话采用的模仿没有一个公共的名称；三音步诗、挽歌体或其他类型的诗的模仿也没有——人们把&诗人&这一名词和格律名称结合到一起，称之为挽歌体诗人或者史诗诗人，他们被称为诗人，似乎只是因为遵守格律写作，而非他们作品的模仿本质。
