Under the condition of reasonable controlling on time of ignition of two level or multilevel spherical charge, the downgoing energy of seismic wave can be improved and the vibration of surface can be reduced.

在合理控制两级或多级球形装药起爆时间条件下，能提高地震波的下传能量，同时减少地表的振动。

According to records of 338 earthquakes in recent years by SK seismograph of Tianshui seismic station, a formula of relationship between travel time difference of maximum surface wave from primary wave and epicentral distance is given by least squares method.

根据天水地震台SK地震仪近年来记录的338个震例的资料，用最小二乘法求出最大振幅面波与初至波到时差同震中距的关系式，并与JB表进行了对比。
