查询词典 boundary value problem

According to the Value Chain Theory,this paper gives a kind of means of performance audit on value-chain analysis after studying the existed primary difficulties ubout performance audit such as lack of metewand and comparable data.At the same time,this study has integrated the practice of some perform- ance audit program.By this way,the auditor investigates and analyses the value chain of performance audit program and its key points,and evaluates its validity and value increment,discloses relational problem...

本文针对当前绩效审计缺乏评价标准和可比数据、难以找到准确的切入点等问题，在价值链管理理论的启示下，结合绩效审计实践中的探索和思考，提出了一套基于价值链分析的绩效审计方法，即通过调查分析被审计项目的价值链及其关键价值点，进而对价值链的内外联系以及关键价值点上作业活动的有效性、增值性等进行绩效评估，发现问题，做出评价，提出审计增值建议。

In the academic circle of political economics, it has been a controversy whether services has value. And now another problem has been raised-on the one hand, the value of labor in services is admitted, while on the other hand, the value of labor in business and bank is denied-which breaks the consistency of the value of service labor in the "political economics" system.

在政治经济学理论界，服务产品是否具有价值的争议尚未了，另一矛盾又普遍出现，即一边承认服务劳动的价值创造性，一边却仍否认商业劳动和银行劳动的价值创造性，使服务劳动的价值创造性在政治经济学体系中无法保持连贯性和一致性。

Basing on this, the formal asymptotic expansion of solution for the original problem is obtained. Finally, under suitable conditions, existence and its uniform validity of asymptotic expansion of solution for the initial boundary value problem are proved,by using theory of differential inequalities.

在这基础上得到了原问题解的形式渐近展开式；最后，在适当的条件假设下，利用微分不等式理论，证明了原初边值问题解的存在性及其渐近展开式的一致有效性。

Then the problem is further equivalent to a kind of Riemann boundary value problem on the real axis by extension of symmetry with respect to the real axis.

利用已有结果得到了该问题的可解性定理。

Firstly, we discuss the boundary value problem of one dimensional biharmonic equation in an interval and its variational problem,multiresolution analysis in the Sobolev space , then solve it with wavelet-Galerkin methods.

首先本文讨论了一维双调和方程边值问题及其相应的变分问题，定义Sobolev空间的多分辨分析，用小波–伽辽金方法进行数值求解，两组基下得到的系数矩阵为七对角阵和块状对角阵。

Secondly, we discuss the boundary value problem of two dimensional biharmonic equation in a rectangular field and its variational problem,discretize it by using dual tensor product of and the direct product and lining up of matrices, we get some special matrices which are the presupposition in exploring the fast computation, then solve the system of linear equations.

其次本文讨论了矩形域上二维双调和方程边值问题及其相应的变分问题，利用二元张量积小波分析和矩阵的直积、拉直技巧将变分问题离散化，从而使求解偏微分方程问题变为求解线性方程组的问题。一维情况两组基的张量积下得到的系数矩阵分别为块状七对角阵和稀疏矩阵。这些特殊结构为以后快速算法的研究打下一个基础。
