摘　　要：本文用广义变分法计算了四角点支承矩形板的弯曲及稳定。文中选用的位移函数满足了板的主要边界条件;从而能得到较好的近似解,且计算比较简便。In this paper the bending and stability of the rectangular plate with supported on four corner points is calculated by the generatized variational method. The displacement functions given in this paper satisfy the chief boundary condition of the plate. consequently the proposed method can obtain a better approximate solution, and is more convenient in Calculation.
