摘要
本文以单键群（ＳＬＣ）分析方法为基础，进行了以下研究：（１）对一个地区的地震目录进行分析得到特征键长，并用其对该区地震的时空群集性和离散性进行分析，进而建立分类子目录，以便作针对性的细致处理；（２）定义了几个描述ＳＬＣ构架特点的参数，发展和实现了按时间逐段滑移计算ＳＬＣ构架和这些参数的办法及程序，考察这些参数随时间的变化（尤其是大地震前的变化）；（３）用以上各软件处理了昆仑山－阿尔金山弧型顶部区域的地震目录，得到了一些有意义的结果。
Based on the method of SLC,this paper worked at 3 respects:(1) Set up a 3 D SLC software which can deal with big catalogue of earthquakes,and analyse the characteristics of earthquakes' clustering and scattering in time space.(2) Definited several parameters to describe the distinguishing feature for the SLC frame,and developed a technique to calculate the 3 D SLC frames and their these parameters with gradually time sliding,and inspected their variations with time,especially before large events.(3) Using these means,treated the earthquake catalogue in the top area of Kunlun Altun Arc,and some valuable results had been obtained.
