1·The article is aimed to help WRM sharp their competitive edge in China market with fast growing but low concentration.

如何帮助WRM在中国的这个高速增长，而整合度低的市场取得竞争优势，是本论文诊断分析的目的所在。

2·The problems of resolution and convergence are increased by classic methods such as FEM and WRM when the solutions exhibit sharp changes.

当在空间位置出现突变时，偏微分方程的经典解法如有限元法和加权残差法等无法保证解的精度和收敛性。

3·An approximate solution on ultimate load of a circular plate under radial and lateral loads is derived from equations by subdomain Weighted Residual Method (WRM) and point by point WRM.

本文应用加权余量法中的子域法和配点法，求出了均匀圆板在径向和横向均布荷裁作用下的极限荷载的近似解。
