采用多项式坐标函数和瑞利-里兹方法计算了边缘受平移和旋转弹性约束的矩形板的基频系数。该方法简单直接，可以解决相当困难的弹性动力学问题。复杂的因素（正交异性、面内力、集中质量等）也可以考虑进去，没有形式上的困难。
The fundamental frequency coefficient for a rectangular plate with edges elastically restrained against both translation and rotation is calculated by using polynomial coordinate functions and the Rayleigh-Ritz method. The approach is simple and straightforward and allows the solution of a rather difficult elastodynamics problem. Complicating factors (orthotropic properties, in-plane forces, concentrated masses, etc.) can also be taken into account without formal difficulties.
