拉氏乘子法和广义变分原理的通式
Lagrange Mutiplier Procedure & General Form of Variational Principles
本文用拉氏乘子法推导了弹性力学广义变分原理的一般形式，证明了"通式"（2）的确是三类变量广义变分原理的泛函。文中"拉氏乘子法"的运用显示了此法的灵活性。同时也指出了此法的盲目性，这是"拉氏乘子法"的局限。
educing the general form of the variational principle in elasticity by Lagrange multiplier procedure.It is approved that the formula（2）was the variational principle's functional with the three kinds of variables.But it seems that Lagrange multiplier procedure can't approve the universality of formula（2）.This is a localization of Lagrange multiplier procedure.
