摘　　要：本文简要介绍了近年来国外在地震震源、台阵(网)资料在震源参数研究中的应用,全球震源谱对比、地震破裂传播方向、遗传算法在震源参数研究中的应用,地震矩、拐角频率、震源尺度、应力降与震源模型的探讨,以及确定初动震源机制的新方法等方面的研究情况和动态,并对其中的研究结果给予了一定的评述。In this paper, we introduce the recent study abroad on the application of array/network data to source parameter study, the global comparison of earthquake source spectra, the direction of earthquake rupture propagation, the applieation of genetie algorithms to souree parameter study, the discussion on seismic moment, comer frequency, focal depth, stress drop and source model, as well as the recent development in the determination of first-motion focal mechanism, and also make some eomments on some research results.
