摘要
通过外场实验,运用Mikroanscan7200V型红外热成像仪分别对TNT、SEFAE和DEFAE同量级的模拟装置爆炸火球的表面温度进行了测量,分析了同量级的TNT、L SEFAE、G SEFAE、DEFAE炸药的温度场的分布情况,结果表明,DEFAE表面温度最高,高温(≥1 000℃)持续的时间也最长;DEFAE的温度场效应要比SEFAE、TNT高;TNT、L SEFAE、G SEFAE和DEFAE在温度场接近最大温度时的火球平均直径的排序为-DDEFAE>-DL-SEFAE>-DG-SEFAE>-DTNT.
Using MikronScan 7200V thermal imager, surface temperatures of blasting fireball of TNT, SEFAE, and DEFAE were measured through field experiments. The temperature distribution of TNT, L-SEFAE, G-SEFAG, and DEFAE with same quality was analyzed respectively. The results show that the surface temperature of DEFAE is highest, and the time of high temperature （≥1 000℃） stay longest. The temperature field effect of DEFAE is more significant than that of SEFAE and TNT. While temperature field approaching highest blast temperature, the order of average diameter file is DDEFAE〉DL-SEFAE〉DC-SEFAE〉DTNT.
