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. Th is method is quasi- stat ic abso lute calibt rat ion on p ressure senso r system used to measure the shock
