【摘要】 中国地区地震P波和S波走时表实测地震的效果如何?本文给出了一系列地震的实测结果,对比J—B表和其他走时表分析表明,建立在中国地区实际观测数据所独立算出的中国地区地震波走时表,更适合于实际情况,用以测定中国地区震中的参数具有较高的精确度。更多还原

【Abstract】 A set of P and S travel time tables from Chinese earthquakes was independently constructed in 1979. As for the effects of the new tables in practical experiments, this paper describes some tests on a number of earthquakes. Compared these tables with Jeffreys-Bullen tables and others, the practical experiences hane shown that the new tables are relatively accuate and more applicable in the Chinese region in determining focal parameters than J-B tables.更多还原
