摘要
热释电介质是许多传感器及机敏结构或系统中的关键材料，本文系统地讨论了在基础理论和数值计算中极具重要地位的各类变分原理．包括准静态变分原理、动态变分原理和关于固有频率的变分原理．最后建立了关于静态压电板的变分原理，并由此导出了各向异性压电板的控制方程及边界条件．
The pyroelectric materials play an important role in smart materials and structure system. This poper presented all kinds of the variational principles for the materials, which are significant in fundamental theory and applications of numerical approach. As examples, the control equation and boundary condition of anisotropic plate were derived from the potential variational principle under some assumptions.
