| 摘 要： | 本文提出了Reissner变分原理的两种等价形式在定解区域被剖分为有限元子域后不再等价的观点,还给出了它们在放松了有限元的单元交界面上连续性条件后的弱等价关系,并讨论了这种不等价性对构造混合/杂交元的影响。

| Abstract: | This paper presents the concept that the two forms of Reissner variational principle are not equivalent after the solved area being divided into some finite element subareas and gives the weak equivalent of them after relaxing continuity coridition on interface of elements. Its influence on constructing the mixed/hybrid element is discussed. |
