| 摘 要： | 本文证明了等价变分原理的泛函,实质上都只相差某种加权残差项,这也就表明了,在已知的泛函后附加加权残差项,是建立等价变分原理最简便的方法.

| Abstract: | It is proved in this paper that the functionals of equivalent variational principles are different essen-tially only by terms of weighted residuals.Consequently,the simplest method to construct equivalentvariational principles is to add weighted residuals to known functionals as first used by Courant. |
