Using the fiber-optic probe technique, the time when the shock wave reachs the different places in steel plate and steel-aluminum plate under contact explosion with insensitive RDX and aluminize RHTL had been separately measured.

利用光纤探针测试技术，实验测量钝化RDX和含铝炸药RHTL分别与钢板、钢-铝板两种靶板接触爆炸条件下，靶板中不同位置的冲击波到达时间。

Experimental investigation indicates that shock wave velocity and shock wave pressure of beginning which were produced with aluminize RHTL were smaller than that of insensitive RDX in steel plate, however, attenuating velocity of shock wave velocity and shock wave pressure which were produced under contact explosion with aluminize RHTL were quciker than that of insensitive RDX in steel plate, when steel- plate had been separately operated under contact explosion with insensitive RDX and aluminize RHTL, and shock wave press had changed suddenly in the interface between steel and aluminum, In the circumstances, the shock wave velocity had ascended suddenly and shock wave pressure had descended suddenly.

实验研究表明：RHTL炸药爆炸加载钢板下，介质中的冲击波初始速度和初始压力相对RDX较小，衰减相对较快；钝化RDX和含铝炸药RHTL分别作用于钢铝复合板时，在分界面处冲击波速度和压力都发生突越，冲击波速度突跃，冲击波压力突降。
