| 摘 要： | The pyroelectric medium is an important material in the application of smart materialsand structures.It is necessary to systematically discuss all kinds of variational principles which play avery significant role in the fundamental theory of mechanics and numerical analysis method.This paperfirstly gives the quasi-static and the dynamic variational principles,then the principles for eigen prob-lems.As a simple example,the principle was finally applied to derive the fundamental equations for ananisotropic piezoelectric plate.
