| 摘 要： | 摄动有限元方法是随机结构分析的基本手段之一．然而对于随机参数摄动与确定性参数摄动的区别与联系的讨论还很少有文献论及．本文尝试进行了这一方面的工作．文中定义了随机摄动解答的具有Ｍ阶精度的渐近展开式的概念．并通过讨论，指出了摄动有限元法的可能研究方向。

| Abstract: | The finite element based perturbation method is a basic technology for stochasic structural analysis.However,there is seldom research focusion on the deference between deterministic parameter perturbation and random parameter perturbation.This paper supplies some notation on the problem.The idea of gradually expansion based on the M'th precision is defined.According to detailed discussion,some potential developing directions are pointed. |
