摘 要：在對現(xiàn)有沖擊波超壓測試方法和特點分析的基礎(chǔ)上，為進(jìn)一步準(zhǔn)確測定彈藥爆炸時產(chǎn)生的沖擊波超壓和沖量，提出了一種可行的間接測量沖擊波超壓的方法，即在求得沖擊波速度的基礎(chǔ)上，利用蘭金--雨貢紐方程（Rankine-Hugoniot）求解沖擊波超壓，用該試驗方法求得的超壓值與壓力傳感器直接測量的超壓值進(jìn)行比對，由此來證明用沖擊波速度測試超壓這種試驗方法的理論可行性。

Abstract： To measure the shock wave overpressure and the impulse more accurate when the ammunition exploded, a feasible way to measure the shock wave overpressure indirectly was proposed by analyzing the means and features of existing shock wave overpressure measurement. On the foundation of getting the speed, utilized the Rankine-Hugoniot equation to solve the shock wave over pressure, then compared the pressure with which was measured by transducer, to prove the feasibility of this kind of experiment.
