一、引言 用实验的方法研究固体炸药爆炸后的反应过程是非常困难的,因为这种反应时间极短,仅几个微秒,反应区的压力和温度很高,可以高达300k bar和6000°K。因此很难研究这一动力学过程。但是这个问题又非常重要。以爆轰产物的测定为例,只有知道了炸药爆炸后形成的产物,才能从理论上计算出爆速、爆压、爆热等爆轰参数,才能对炸药的作功能力进行评定,从炸药爆炸后形成的产物对人体是否有害这个角度看,了解爆轰产物的具体组成,对于配制和选用矿用爆破炸药,也具有至为重要的现实意义。
I. INTRODUCTION It is very difficult to experimentally study the reaction process after explosion of solid explosives because the reaction time is very short, only a few microseconds, and the pressure and temperature in the reaction zone are very high, up to 300k bar and 6000 ° K. It is therefore difficult to study this kinetic process. But this issue is very important. Take the determination of detonation products as an example, only by knowing the products formed after the explosives explode, we can theoretically calculate detonation parameters such as detonation velocity, detonation pressure and detonation heat to evaluate the workability of explosives. After the formation of the product on the human body is harmful from this perspective, to understand the specific composition of detonation products, for the preparation and selection of mining explosives, also has a very important practical significance.
