摘　　要：介绍了炸药爆炸能量的水中测试方法,对TNT和3种新设计的含铝炸药进行了水中爆炸的实验研究,比较了各炸药的爆炸性能。结果表明,发现冲击波峰值超压、冲量和冲击波能流密度等参数较好地符合爆炸相似律,得到了新配方各参数的爆炸相似律系数。计算了炸药的冲击波能和气泡能,并提出了计算爆炸总能量的方法。把实验测得的炸药的总能量与KHTR程序计算的爆热进行对比,二者符合得较好,说明了KHTR程序可用。The underwater testing method for explosion energy of explosives was introduced. The explosion properties of TNT and several aluminized explosives were studied through underwater explosion experiments. The underwater explosive performance of different explosives was compared. The results show that the performance parameters （shock wave peak pressures, impulse and energy flux） accord with explosion similar rules, and the explosion similar equation coefficient of these performance parameters for new formulation was obtained. The shock wave energy and bubble energy of these explosives were calculated and the method for calculating total energy was introduced. The detonation heat calculated by KHTR was compared with experimental total energy, showing that the experimental result is very consistent with the calculated one, the program KHTR to calculate detonation heat can be used.
