摘要: 采用高速运动分析系统观察了高能炸药、含铝炸药和温压炸药爆炸产物抛撒的过程；比较了这3种炸药的爆炸产物抛撒运动及后燃特点，通过比较直观地观察到温压炸药爆炸和后燃2个过程，以及后燃火球的成长历程；根据实验结果确定了温压炸药爆炸产物抛撒半径随时间变化的数学表达式。

Abstract: The rapid dispersal process and phenomena of high explosive, aluminized explosive and thermobaric explosive were investigated experimentally by using a high-speed framing camera. By comparing the characteristics of the dispersal process and afterburning of the three kinds of explosive, two processes of explosion and afterburn of the thermobaric explosive, and the development history of the afterburn fireball were observed. Based on the experimental results, a formula was proposed to discribe the variation of the dispersal radius of the thermobaric explosive explosion production with time.
