We have joined the World Trade Organization The establishment of an import relief system that abide by WTO agreement is the right and duty of any WTO contracting party. This course is aimed at studying the International Trade Policy changed which affected industrial competition Strategy Also, we compare the safeguards law and practice of USA, EU, Australia, Canada, Mainland China, Korea, Japan, Vietnan, Newzealand, phillippine, Indonesia as well as the rule of WTO safeguards agreement, so as to understand the "safety valve" and industry adjustment roles under safeguards system of each country in the free trade environment. Eventually, we will reduce trade flow an applicable and suitable import relief system, which cause distortion and maintains a fair trade circumstance.

我国已正式加入世界贸易组织，「经济专题讨论--国际贸易政策与产业竞争策略」主要在探讨美国、欧盟、澳洲、加拿大、中国大陆、韩国、日本、越南、纽西兰、菲律宾、印尼等主要国家之进口救济制度与实义，及其与我国与世界贸易组织乌拉圭回合协定下主要贸易国之制度作乙比较，期能了解各国进口救济制度在贸易自由化政策发展过程中所扮演「安全阀」及促进产业转移调整的角色，进而能建立一套国内法中客观可行之运行程序及合理救济制度，减少对贸易流量造成扭曲，使市场竞争更趋公平合理。

分别滴加不同浓度的抗原使其发生反应，测量傅里叶变换红外谱和加入抗体前后反射谱的变化，结果表明硅烷化效果明显，生物抗原较好的固定，抗原抗体反应前后反射谱有明显的红移，且红移量于滴加抗原浓度增加而增加，并且呈现出良好的非线性关系。

Combining the experimental results and theoretical analysis, the following work has been accomplished.(1) Reasons of the decrease of interelectrode capacitance and the increase of discharge gap caused by the powder suspended in dielectric fluid are explained. And the mechanism that surface quality of workpiece improved by powder-mixed EDM is analyzed from this viewpoint.(2) The variation regularity of the percentage of silicon on the machined surface of workpiece has been summarized according to the experiment results when silicon powder was added into the working fluid. The entropy is introduced to explain the reasons for this variation regularity by thermodynamics.(3) The dimensional accuracy is greatly influenced by the overcut resulting from discharge gap and electrode wear in practice application. Empirical formulas for the overcut in EDM and powder-mixed EDM are established based on the experimental results using the ternary linear regressive method in this paper.(4) The influence of main factors on the machined surface characteristics has been evaluated based on the orthogonal experimental design method.

通过一系列普通电火花加工与混粉电火花加工的对比实验，运用工艺实验和理论分析相结合的方法，重点做了以下工作：(1)探讨了粉末颗粒导致极间电容减小、放电间隙增大的原因，并从这个角度解释了混粉电火花加工可以改善工件表面质量的机理；(2)以混合硅粉的电火花加工为例，实验得出峰值电流和脉冲宽度对加工表面层成分中硅元素含量的影响规律，并引入熵的概念从热力学的角度对硅元素含量变化的原因寻找了理论依据；(3)在实际加工中，由于粉末的加入使放电间隙变大，这使得混粉电火花加工的尺寸精度难以控制，本文利用三元线性回归的方法，在实验数据的基础上，建立了两种电火花加工过切量的计算公式；(4)将正交试验法应用于混粉电火花加工实验研究，并通过对实验指标极差的直观分析，得出各电参数对加工指标影响的敏感程度。
