摘要
本文引用并推广文的分区最小位能原理,提出并论证了动力学分区变分原理,并进一步采用钱伟长提出的引入拉格朗日乘子并加以识别的方法(1980,1985),得到了不完全和完全的动力学分区广义变分原理。本文采用笛卡尔张量符号。
In this paper, dynamic region-wise variational principles have been developed and proved by extending regionwise potential energy principles. Furthermore, we have . gotten dynamic region-wise generalized variation principles by the method developed by prof. Chien Weizang, introducing Lagrangian multipliers and distinguishing them (1980, 1985). Cartesion notations are used in the paper.
