摘要: 根据温压炸药的爆炸特性，采用红外热成像仪研究温压炸药的爆炸温度。通过对实验结果的分析发现，与等量TNT相比，温压炸药爆炸云团温度较高，高温持续时间是TNT的2~5倍，高温云团体积可达TNT的2~10倍，体现了温压炸药相对于传统高能炸药的温度场优势。药剂被引发后所形成的高温环境，足以维持其中铝粉的后续快速燃烧反应，从而为增强爆炸冲击波提供帮助。

Abstract: The infrared thermography method was used to investigate the detonation temperature of thermobaric explosives (TBE). The experimental result shows that the temperature of TBEs detonation cloud is higher than that of TNT with the same weight. The duration of high temperature and the volume of the high temperature cloud are 2~5 and 2~10 times as much as those of TNT, respectively. This implies that TBE is superior to the traditional high explosive on the temperature field. The high-temperature environment formed by the explosive explosion is sufficient to maintain the afterburning of the aluminum powder，which can provide assistance to boost up the blast wave.
