1985年作者编算了甘青区域地震波走时表,采用双层地壳模型,H_1=22.0公里,V_(p1)=6.10公里/秒,V_(s1)=3.55公里/秒,H_2=29.5公里,V_(p2)=6.47公里/秒,V_(s2)=3.81公里秒,H=51.5公里,V_(pn)=8.17公里/秒,V_(sn)=4.62公里/秒。表中除了按通常走时表给出了(?)、(?)、P_2、S_2、P_n、S_n波的走时外,还给出中间层界面上的反射波P_1、S_1和莫霍界面上的反射波P_n、S_n的走时。该表使用方便,比用单层模型计算的甘肃及邻近地区地震波走时表更接近实际,比用甘肃地区的4层定位模型计算的走时精度高。
In 1985, the authors calculated the travel timetable of the Gansu regional seismic wave and adopted the double crustal model with H_1 = 22.0 km, V_ (p1) = 6.10 km / s, V_S1 = 3.55 km / s, H_2 = 29.5 km, (p2) = 6.47 km / s, V s2 = 3.81 km sec, H = 51.5 km, V pn = 8.17 km / sec, V sn = 4.62 km / sec. In addition to the travel time of (?), (?), P_2, S_2, P_n and S_n waves in the table, the reflected waves P_1 and S_1 on the interface of the intermediate layer and the reflections on the Moho interface P_n, S_n travel time. The table is more convenient to use and is more realistic than the travel timetable of seismic waves in Gansu and its adjacent areas calculated by the single-layer model. It has higher travel time accuracy than the four-layer positioning model of Gansu.
