摘要

摘要: 引入一个新的物理量压力减敏程度，来更合理地表征乳化炸药发生压力减敏的难易程度，为研究其作用机理提供量化的分析工具。分别利用乳化炸药发生压力减敏前后的爆炸冲击波峰压及其对数、冲击波能量和总能量计算压力减敏程度，比较并分析计算结果的优劣。结果表明，几个参数计算的结果都能达到相近的效果，用冲击波峰压计算起来简单方便，冲击波能量计算效果较好。用冲击波参数计算的压力减敏程度能够反映乳化炸药压力减敏的本质，建议采用冲击波峰压计算压力减敏程度，在数值差别不明显时采用冲击波能量来计算。

Abstract: A pressure desensitization degree parameter was proposed to characterize desensitization of emulsion explosive and offer a quantificationally analyzing tool for studying its action mechanism. Pressure desensitization degrees were calculated with parameters, such as peak pressure, its logarithm, shock wave energy and total energy of explosion shock wave, which were respectively produced by emulsion explosive before or after desensitization. Calculated pressure desensitization degrees were similar with different parameters. Calculation with peak pressure was simple and the result calculated with shock wave energy was better. Research results show that pressure desensitization degree calculated with shock wave parameters can reflect the pressure desensitization essence of emulsion explosive.
