In this articl, the background, the thoretical source and the basic content of Cuvis catastrophism are discussed, It is shown that it is not a subjective fabrication by Cuvier, but rather it is inherited from reforming former catastrophic ideas, on the basis of his long-term scientific practic, Therefore it helped to push forward the dvelopment of gology and biology.

本文论述了居维叶灾变论的产生背景，理论来源及其基本内容，证明它并不是居维叶的主观臆造，而是他在长期科学实践基础上对前人灾变思想的继承和改造。因此它对地质学和生物学的发展曾起到巨大推动作用。本文还论述了居维叶灾变论与其它灾变学说的区别；并列举大量现代科学发现证明居维叶所谓的灾变是不可否认的事实，是自然界中具有确定原因的必然发生的历史事件。

NET technology structure dynamic webpage in realizing in system, is it use personnel can choose to analyze the function through interface conveniently to make, the analysis result trends show with the chart; And has fully utilized treatment technology of running side by side, has considered the loss which sets up the index and resource proportionally, make systematic efficiency be optimized. Pass the imperial examinations at the provincial level several systematic example of practical application in thesis, if customer state analysis, income analysis, conversation situation analysis, is it transfer to situation analysis, rival analyze etc. to breathe out, having proved the system through the actual inspection of market analysis personnel, the analysis conclusion drawn from it is accurate, can be believed, and because of is it with chart, it makes to be very clear to analyze person, can catch the focal point easily to mix, have convincingness even more as to policy-making level of enterprises. System produce high benefit relatively already at present, can is it grasp message, consumption situation of customer in real time to realize easily through it, turn from enterprise policymaker to network analysis monthly demand of conclusion into and require that analyses rivals situation every day, draw occupation rate of market key index can know system become market important basis source of decision already, so, the realization of this project has greater actual meaning.

NET技术构建动态网页，使应用人员能方便地通过界面选择分析功能，分析结果动态以图表显示；并充分利用了并行处理技术，对建立索引与资源的损耗均衡考虑，使系统效率得以优化。3、在论文中举了几个系统实际应用的例子，如客户状态分析、收益分析、通话情况分析、呼转情况分析、竞争对手分析等，证明系统经过了市场分析人员的实际检验，从中得出的分析结论准确、可信，并由于配以图表，使分析人员一目了然，可轻易抓住重点，对企业决策层而言则更具说服力。4、系统目前已产生了较高的效益，通过它能轻易实现实时掌握客户的信息、消费情况，从企业决策者对系统分析结论的月需求变为要求每日分析竞争对手情况，得出市场占有率等关键指标可知系统已成为市场决策的重要依据来源，因此，本项目的实现具有较大的实际意义。

Then the boundary element integral equation of interior and exterior form is deduced in detail, also the form with corner coefficient. The significance for numerical calculation and principle of the singular integral is analyzed, and a non-isoparametric transformation method is presented to calculate weak singular integral and Cauchy integral, the method presented provides us a very simple way to computer the two kinds of singular integral of Helmholtz boundary integral equation, and it is easy to program in computer. After the difficulty of the calculation for multi-frequency of Helmholtz boundary element is explained, a method named SECHIEF (Series Expansion Combined Helmholtz Integral Equation Formulation), which is focused on the computational efficiency, is presented.

对结构声辐射的边界积分方程的内部形式与外部形式进行了详细的推导，给出了角点系数的计算方法与边界积分方程的形式，在此基础上，分析了奇异积分产生的原理及其对数值计算的重要性，提出了一种计算奇异积分的非等参(来源：Ae8a8BC论文网www.abclunwen.com)单元的变换方法，该方法给Helmholtz 声学边界积分方程中的弱奇异积分与Cauchy 奇异积分的计算以及编程提供了极大便利。
