摘　　要： 讨论了在软支承、尤其在悬挂支承的情况下,支承对本征频率的影响。从波动方程出发,导出频率改变的一级近似公式。结果表明,在某些条件下这种影响可以忽略。 A suitable support must be used to offset gravity when a gravitational waves antenna is operating. If the supported points deviate from the perfect points——nodes, a change of eigen frequency of the antenna will be caused. In this paper, the influence of soft support on the eigen frequency has been discussed, especially in the case of suspending formalism. A formula of the frequency change has been deduced from the wave equation to the first order approximation. The result shows that this influence can be ignored under certain conditions.
