摘要
Abstract
The modified gap test setup was designed. The input pressure of acceptor explosive was measured by applying a PVDF gauge, and the motion images of the free surface were recorded by u-sing a high-speed frame camera. The relation between the free-surface particle velocity and input pressure of explosive were obtained and compared with the calculated free-surface particle velocity of unre-acted explosive. Comparison shows that the chemical reaction threshold and ignition threshold of explosive JO-9159 are 1. 33 and 1. 98 Gpa, respectively.关键词
