摘　　要：本文采用边界层校正法,对截顶旋转薄壳低频轴对称自由振动问题给出了不同于文[3]的解法。给出了圆柱壳的数值算例。The low-frequency axisymmetric free vibration of truncated thin shells of revolution is analysed by using the method of boundary layercorrection that differ from the method in the monograph [3]. Finally, a numerical result of cylindrical thin shell is given.
