A newly developed method for detonation pressure measurements-impedance matching method-is described in this article.Transparent liquid diiodomethane (CH2I2) is used as the inert medium, which can meet the shock impedance matching condition with many high explosives of properly chosen charge densities. In the experi ments,using high accurate PWGs, small scale optical pins and a high speed streak camera with a scanning speed of 7.50mm/μs manufactured in China,the initial shock wave velocities in CH2I2 under the shock-impedance matching condition are measured. Then, from the Hugoniot relation of CH2I2 and the interface continueous equations, the impedance matching detonation pressure can be obtained by simple calculation.In our experiments impedance matching detonation pressures of 5 typical high explosives were determined by this method. Comparing with other methods for detonation pressure measurements,impedance matching method has relatively more reliable theoretical foundations, higher accuracy and simpler experimental technique. We hope that on the basis of this work an accurate and reliable method for routine detonation pressure measurements can be developed.We will continue our work in this direction.

A new accurate method-diiodomethane method-for routine detonation pressure measurement of explosives has deen developed on the basis of impedance matching method. CH2I2 is used as the inert material, initial shock velocity in it is measured by high speeb camera with multiple slits and detonation pressure is calculated by acoustic approximation method. For high denstiy charges of high explosives with impedance ratios ranged from 0.94 to 1.10, detonation pressures in good agreement with those of the impedance matching method can be obtained. So, we recommend diiodomethane method as a routine method for detonation pressure measurement of high density charge of high explosives.

在阻抗匹配法的基础上发展了一种比较精确的爆压例行测试方法——二碘甲烷法。用二碘甲烷(CH_2I_2)作惰性材料,采用多列狭缝扫描照相测定CH_2I_2中的初始冲击波速度,用声学近似计算爆压。对于猛炸药高密度药柱可以得到跟阻抗匹配法一致的爆压,从而此方法可以作为猛炸药高密度药柱爆压的一种比较精确的例行测试方法。
