非均匀炸药冲击起爆和起爆后的行为

 介绍并分析了Campbell 等人及其他作者研究非均匀炸药冲击起爆和起爆后行为所获得的实验结果，但不涉及其冲击起爆条件。足够强的冲击波进入非均匀炸药后，爆轰将瞬时（指不经过感应时间）且直接（指不经过其他过程，如爆燃）被引发；非均匀炸药起爆后，其中传播的自始至终是一个不断增长的爆轰波，直至发展为正常爆轰，整个过程都是爆轰的增长（新定义）过程。不存在由反应冲击波不断增长并转变为爆轰波的所谓向爆轰的增长。所谓向爆轰的增长，实际上是爆轰的增长（按新定义）的初期；Craig原定义的爆轰的增长，实际上是爆轰的增长（按新定义）的后期；而所谓反应冲击波，实际上是增长中的初期爆轰波。爆轰的增长（按新定义）是所有猛炸药的特性，炸药反应不充分并逐渐趋于充分是爆轰的增长的化学机制。

Behaviors of Shock Initiation and after-Initiation for Heterogeneous Explosives

Campbell's and other authors' experimental studies of behaviors of initiation and after-initiation for heterogeneous explosives were introduced and analyzed,but initiation conditions were not dealt with.When an intense shock wave enters a heterogeneous explosive charge,detonation is initiated by the shock wave instantaneously(i.e.not to undergo induction time) and directly(i.e.,not to pass through other processes,such as deflagration).Then a building up detonation wave propagates throughout the heterogeneous explosive charge until it develops into a normal detonation.This whole process is called the buildup of detonation with the new definition in this paper.The so-called reactive shock wave is the building up detonation wave in early stage.Buildup of detonation(in terms of new definition) is a characteristic for all secondary explosives.Incomplete reaction and running to complete reaction of explosives are the chemical mechanism of buildup of detonation.
