摘要
运用红外热成像仪Mikroanscan7200V分别对TNT、SEFAE和DEFAE爆炸火球的表面温度进行了测量,讨论了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(≥1000℃)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为-DEFAE>-G-SEFAE>-L-SEFAE>-TNT。
Using the Mikroanscan 7200V Thermal Imager, the blasting fireball＇s surface temperature of TNT, SEFAE,and DEFAE were measured. The temperature distribution of TNT, L-SEFAE, G-SEFAE and DEFAE explosives are discussed. The results show that,for the four equal-quality explosives,surface temperature,the time of high temperature （≥1000℃）and temperature field effects of the DEFAE is highest,longest and best. Approaching the highest blasting temperature,the fireball＇s average diameter iS.D^-DEFAE〉D^-G-SEFAE〉D^-L-SEFAE〉D^-TNT.
