| 摘 要： | 通过建立广义能量原理和广义虚功原理，统一地导出了胡海昌 鹫津久一郎广义变分原理、ＨｅｌｌｉｇｅｒＲｅｉｓｓｎｅｒ 广义变分原理、戴天民全能量原理和胡成栋混合能量原理。广义虚功原理给出了现有变分原理的一种统一导出形式，并为发现新的变分原理创造了某种可能的新途径。

| Abstract: | A generalized energy principle and a generalized virtual work principle are presented. Hu|washizu generalized variational principle, Helliger|Reissner generalized variational principle, Dai Tianmin full energy principle and Hu Chengdong blending energy principle can be directly deduced from the generalized virtual work principle. The generalized virtual work principle is a general form of the existing variational principles, and it offers a fresh approach to a new variational principle. |
