【Abstract】 Through using the high-speed digital camera technology,research is carried out on dynamic combustion process of silicon delay explosive,In addition,instantaneous velocity as well as average velocity of the combustion of silicon delay explosive is calculated.The test result shows that not only the spreading process of burning wave front can be seen clearly but also the combustion velocity of delay explosive can be reckoned by using high-speed digital camera technology.Besides,findings indicate that the combustion process of silicon delay explosive is characteristic of obvious nonlinear screeching.更多还原
