摘　　要：本文给出了边缘转动受弹性限制矩形板横向振动固有频率的一个近似解法，不但公式简单易程序化，而且有着较高的精度，本文最后给出了一些算例，并与已有结果作了比较．This paper presents an approximate solution for calculating eigen-frequencies of transverse vibration of rectangular plates with elastical restrained against rotation along edges. The formulae are not only very simple and easily programmed but also haye high accuracy. Finally, some numerical results are given and compared with other results obtained.
