用高速分幅摄影测试方法研究聚能装药的射流形成过程 ,对两种不同背景光条件下射流形貌的分幅摄影效果进行了分析研究 .为了拍摄到射流的真正形貌 ,需要为射流的运动提供真空环境 ,在实验中采取了射流在其内运动的有机玻璃管中抽真空的办法 .实验结果表明 ,只要有机玻璃管的真空度能够满足要求 ,采用双反射镜成像系统来观测射流的形貌是可行的 . The formation process of charged charge jet was studied by high-speed sub-photogrammetric test method, and the effect of sub-photogrammetry of jet flow under two different background conditions was analyzed.In order to capture the true shape of jet, Of the movement to provide a vacuum environment in the experiment to take a jet in which the movement of the plexiglass tube vacuum method.Experimental results show that as long as the degree of vacuum plexiglass tube to meet the requirements of the dual mirror imaging system to observe the jet The appearance is feasible.
