摘要
本文利用拉氏乘子法系统地导出了耦联势能和余能原理。
In this paper, coupled potential energy and
complementary energy principles, coupled generalized
potential energy principles and generalized complementary
energy principles with the two and three kinds of variabls
are derived systematicaly by means of the method of
lagranges multiplies.
