摘要: 利用锰铜计、PVDF计和电气石计分别测量了TNT/RDX（40/60）炸药球水中爆炸波峰压，得到了在1R/R0400比例距离范围内的峰压衰减规律。利用电气石计得到的爆炸远区压力时程和气泡脉动周期资料证实了水中爆炸测试法评估炸药能量的可行性。Abstract: Peak pressures of underwater explosion wave by a spherical charge of composition B-3 are measured by using manganin gauge, PVDF gauge and tourmaline gauge over scaled distance of 1R/R0400, and the attenuation of the peak pressure is obtained. The explosion energy of composition B-3 is worked out from pressure profiles obtained by tourmaline gauges and the data of the first pulsation period of gas bubble. This energy is similar to the value from the explosion heat test. This result proves the possibility of assessment of explosive energy by using underwater explosion test.
