对数十种材料的隔爆性能进行了研究。用上下法分别求出不同材料的雷管径向殉爆以及轴向殉爆的半爆距离Ｌ５０。针对材料密度小，隔爆效果好的要求，定义了一个既考虑材料密度又考虑其隔爆性能的优化参数，并以此作为判据，对实验材料进行了优选
The detonation performance of dozens of materials was studied. Using the upper and lower method, the detonation radial detonation of different materials and the semi-explosive distance L50 of axial detonation were obtained respectively. Aiming at the requirements of material density and flameproof effect, an optimization parameter which not only considers the density of material but also considers its flameproof performance is defined and used as the criterion to optimize the experimental materials
