摘　　要：用红外热成像仪对温压炸药和常规炸药的火球特征参数进行了测量,发现温压炸药的热辐射远大于普通炸药。用高速摄像记录了温压炸药的二次爆炸现象,通过与B炸药的爆炸过程对比,发现二次爆炸对温压炸药的爆炸火球具有一定的增强作用。The fireball characteristic parameters of the thermal-baric explosive（TBX） and conventional explosives were measured by the method of infrared imaging technique. The data obtained indicate that the heat radiation of the TBX fireball is far stronger than that of conventional explosives. The secondary explosion phenomenon of the TBX was recorded by high speed video. Blast processes of TBX and Comp. B were compared, and it was found that the secondary explosion has certain enhancement function on TBX blast fireball.
