摘　　要：在地震断层参数的反演中,选取合适的反演方法,对于反演的结果具有至关重要的意义,模拟退火法是一种非线性的反演方法,为了验证此方法在地震断层反演中的准确性,以2004年的仲巴6.7级地震为研究对象,采用模拟退火的方法,通过调用Rongjiang Wang的Okada程序,对用四叉数方法处理过的INSAR地震数据进行反演,从而得到该次地震的断层参数。It is very important for the inverting result to select appropriate inverting method in the inversion of earthquake fault paraineters. Simulation annealing method is a non-linear inversion method. In order to validate the veracity of the method in earthquake fauh inversion, the 2004 Zhongba earthquake of M6. 7 is studied by using the simulation annealing. Using Okada program written by Rongjiang Wang, the INSAR earthquake data processed beforehand by the method of quarter-number is inverted and the fault parameters of the earthquake are figured out.
