In this thesis, the virtual boundary integral equation is based on double layer potential with the virtual density to be determined on virtual boundary. Since this integral equation related to double layer potential only involves the computation of the normal derivative and second normal derivative of fundamental solution, the exponential integral function is not involved in it, so numerical computation for the exponential integral function is avoid.

本文则基于双层位势，引入虚拟矩密度函数来建立虚边界积分方程，并首先对时间变量进行解析积分，在虚、实边界上采用常单元和等额配点离散，该方程只涉及含基本解的法向导数及其二阶法向导数项的计算，对时间变量进行解析积分后，不会出现对指数积分函数的空间变量的积分计算。

This thesis probes into the double negative "bu M bu" construction in modern Chinese, characterizing the nature of this construction, comparing it with the positive counterparts to analyze the strength of its tone, and differentiating the semantic feature of the relevant expressions, so as to enhance the comprehension of the constructions of the modal double negation in modern Chinese.

我们考察了"不M不"格式的语言单位性质，对比分析了"不M不"格式与相对的肯定式在语义和语气表达上的差异，并对容易混淆的两对近义格式"不能不"和"必须"、"不得不"和"不能不"做了辨析，深化了对情态动词双重否定的认识。
