| 摘 要： | 从热爆炸理论出发，推导了炸药临界热点参数的计算公式，计算了TNT、B炸药和EAKR分子间炸药等几种熔铸炸药的热点尺寸和临界点火温度，将这些计算结果分别与101kg落锤和400kg大落锤测定的撞击感度实验值进行了比对，结果表明临界热点参数的计算较好地说明了这几种炸药的感度排序。

| Abstract: | This paper was an attempt to investigate the possibility of estimating qualitatively or quantitatively the impact sensitivity of melt cast explosives by thermal explosion theory. With the formulations deduced from thermal explosion theory to calculate the critical initiation conditions of explosive such as temperature and size of hot spots,the critical initiation parameters of TNT, Comp.B and EAKR intermolecular explosives were calculated,and the calculation results were in good agreement with the experimental impact sensitivity data obtained experimentally from 10 kg hammer and 400 kg heavier hammer impact tests respectively. |
