用光电技术研究高能炸药反应区宽度

Reaction Zone Width of High Explosive by Photoelectric Technique

利用光电技术对JO-9159和JB-9014炸药反应区宽度进行了研究。采用氯仿作为窗口材料,通过瞬态光学高温计测得氯仿中冲击波前沿的发光强度,然后由界面连续性条件及镜像反演规律获得炸药的反应区结构参数。结果表明:JO-9159炸药有明显的CJ点存在,而JB-9014炸药则没有,JO-9159炸药反应区宽度随着装药密度的降低而减小。

The photoelectric technique for studying detonation reaction zone of high energy explosive was presented and used to investigate the reaction zone widths of JO-9159 and JB-9014 explosives. The radiation intensity history of the shock front in chloroform was recorded by using chloroform as the window materials with an instantaneous optical pyrometer. Then the reaction width was obtained by the condition of interface continuity and the phenomena of mirror deduction. The resuJts show that there is a obvious CJ point in the reaction zone of JO-9159 explosive, but not the case for JB-9014 explosive, furthermore, the reaction zone width of JO-9159 explosive decreases with the decreasing of explosive density.
