提出了结构参数发生较大变化时，计算结构的静力响应，固有频率与固有振型的高效的、适用范围广的方法；对非线性保守系统的自由振动，建立了既适用于小振幅又适用于大振幅的近似解析解法。

However, because of the positive sequence of fundamental frequency, there are still some shortages for wavelet transform in the use of harmonic measurement of three-phase dissymmetrical system. A new approach of harmonic measurement based on Period-interleaving of MALLAT arithmetic for dissymmetrical system is put forward. Analysis and experiment based on TMS320LF2407 Digital Signal Processor are made. And the result of experiment reveals that the proposed method based on Period-interleaving is valid in the use of harmonic measurement of three-phase dissymmetrical system.

但是，目前小波变换在三相不对称系统的谐波检测中存在着无法分离基波正序信号的不足，本文就此提出了一种用于三相不对称系统的基于周期交错的小波MALLAT多分辨率分解的测量方法，详细介绍了该算法的原理、流程及计算公式，同时以TMS320LF2407数字信号处理器为核心建立了实验系统对该算法进行了实验，实验结果证明该周期交错－小波变换算法可以有效地检测出三相不对称系统中的有害电流。

By Galerkin meshless method, the equations of motion of static rectangular membrane is established. The first ten natural frequencies of the different aspect ratios and the different pull ratios of rectangular membrane with four clamped edges, three clamped edges and one free edge, two opposite free edges and other two clamped edges were calculated. It is feasible and valid to solve the transverse vibration problem of membrane by Galerkin meshless method.
