| 摘 要： | 1.硬支承和软支承在引力波的作用下,弹性天线体中形成一个位移振动场(位移是时间和空间的连续函数),场中可能有若干个位移为零(不动)的点——节点.节点可以在真实的弹性体内,也可以在假想的延伸弹性体中. 为了克服地球的重力,天线在运行时必须采用适当的方式支承.理想的支承点当然是天线的节点,因为这样不会影响天线的本征频率和它的Q值.但由于种种原因,有时不得不让支承点与天线的节点有所偏离,这就必须考虑支承所引起的一些效应.本文研究支承方式对天线Q值的影响. 支承方式可以分为软支承和硬支承两类.所谓硬支承,是指在支承条件下完全不让天线中的支承点运动,这实质上是使支承点成为天线位移场中新的节点,因而也就完全

| Abstract: | The gravitational wave antenna must be supported during the operation, in order to cancel its weight. The ideal supported points are nodes of antenna. However, for a variety of reasons, sometimes the supported points may deviate from the nodes of antenna, and that must influence Q factor of the antenna. In this paper, we have considered the supporting formalism which influence on Q factor of antenna in general aspect, and have obtained some significative results. |
