山西地区分区近震走时表的编制与检验

主要以山西太原、大同、临汾３个遥测台网的记录，结合山西省内及邻省部分台站的地震观测资料，用勘探、爆破与测震方法得出山西地区地壳模型结构。用观测走时与理论走时对比，划分出６个区域，计算出＂山西地区近震走时表＂及＂山西南部地区近震走时表＂。检验结果表明，发震时刻、震中位置及深度等各项参数较Ｊ－Ｂ走时表均有极大的提高。经试用确认其适用于山西地区。

COMPILATION OF NEAR EARTHQUAKE TRAVEL TIME TABLE IN SHANXI PROVINCE WITH AFTER EFFCT EXAMINATION

Based on the recordings from Taiyuan,Datong and Linfen three telemetered seismic networks in Shanxi province, and those from Shanxi and nearby stations, the crustal model structures are described by exploration,explosion and seismometry. Six divisions are made after comparing observed travel time with theoretical travel time. Two tables as "The nearearthquake travel time table in Shanxi region"and "The near earthquake travel time table inthe south of Shanxi region"are analyzed. After examination,the results showed that the precisions of earthquake origin time,epicentral location, focus depth and other parameters are increased a lot,much more higher than those in J-B travel time table. It is concluded that thistable is accurate,and fits for Shanxi region.
