Abstrsact　The significance of measuring the shock wave is illum inated. The exist ing methods used to measure the shock wave are int roduced. The existed p roblem s of th is k ind of methods are analyzed. Po int ing to the exist2 ed p roblem s, a suitable and new quasi- stat icmethod is put fo rward to imp rove p recision of measuring the shock wave.
