The one is Pagano method which has been proven effective to static problems, but it is very complicate for the three-dimension dynamic problems of finitely long piezoelectric laminated plates.

• 同时，指出Pagano方法求解动态问题所遇到的困难，为克服这些困难，提出了一种求解压电层合板动态问题三维精确解的幂级数展开方法．应用这种方法，可以避免常用的pagano方法求解动态问题所遇到的困难，使求解变得简便，适用范围更广．应用这种方法分析了有限长压电层合板振动问题。
