摘　　要：利用经验Green函数方法 ,用 1996年云南丽江地震后的ML4 7级地震合成了这次地震的最大余震Ms6 0的加速度记录 ,通过与实际记录在频域和时域的对比研究 ,分析研究了地震动特征和这次最大余震的可能破裂特征 ,并对经验Green函数方法进一步的改进方向进行了探讨。Using empirical Green's function method and the M L4 7 aftershock of the 1996 Lijiang earthquake,acceleration record of the largest aftershock with Ms 6 0 for the Lijiang earthquake is synthesized;the characteristics of the earthquake ground motion and the possible rupture features for the largest aftershock are analyzed and studied from comparison of frequency and time domains between synthesized and practical records,and further improvement of the empirical Green's method is approached.
