摘要
本方法通过对区域地震体波振幅传播特征的研究并测定地震能量辐射系数企图得到中强震孕育的源兆信息。本文给出了方法的思路、介绍了参数的物理意义及正常理论值的估计。这一方法无论在目前模拟台网的观测条件下或将来数字观测台网建成之后均可方便、快捷使用。还对方法的使用误差、震例效果和存在问题进行了讨论。
The characteristics of the amplitude propagation of body waves from regional earthquake are studied and the radial coefficient of seismic energy is determined to obtain the source precursor information of moderate earthquake preparation. The thinking of the method is given, and parameter physical significance and the estimation of normal theoretic value are presented. The method is conveniently and quickly applied for either simulation or numerical networks finally, the error, case efficience and unresolved problems of the method are discussed.
