摘要
利用随机生成的理论地震走时数据,取2、5、10、15 km作初始深度,对用双差定位法给出的定位深度结果进行分析。通过模拟计算,认为初始深度误差对双差定位法的空间位置影响较小,但对深度结果有一定影响。
Using randomly generated seismic travel time data, taking 2,5,10 and 15 km as the initial positio- ning depths, the relocation positioning depths which are deduced by the double-difference algorithm inversion are analyzed. The results show that the error of the initial depth has little effect on the relocation position which is de- duced by the double-differential algorithm, but has certain influence on the depth.
