摘要
本文评述了实验应变／应力模态分析进展的若干基本问题。主要是：应变响应与位移响应的关系；应变频响函数矩阵的特点及其测量方法；应变模态的加权正交性及其识别方法；以及其他问题。
This paper comments several fundamental points of experimental strain/stress modal analysis. They are mainly: 1. the relationship between displacement response and strain response ; 2. the peculiarproperties of strain frequency response function and the test methos; 3.orthogonal proprties of strain modes; 4. strain mode identification and others.
