This modification incorporates explicitly the duration of strong earthquake groundmotion into the time dependent variation of the root-mean-square peak amplitude.
这个修正明显地将强震运动的持续时间包含在均方根振幅依赖于时间的变异中。

The effect of explosive characteristic on the amplitudeof explosion seismic wave is studied by means of comparing experiments on groundmotion caused by FAE and TNT located near the ground.
The seismic stress amplitudeof the lower layer is larger than that of the upper layer under near-field groundmotion, and under far-field ground motion the condition is opposite.
