  1. The method is described as follows : the velocity of the moving part and the gas chamber pressure were measured with a dynamic test measurement system ; a dynamic model was built on force analysis of the moving part ; the total kinetic resistance replaced the horizontal friction and water resistance ; then the resistance - velocity relation curves at moving stages were obtained ; with the empirical formula of the gas chamber pressure and the resistance - velocity relation curves, the preliminary dynamic characteristics were analyzed and the structural form and key parameters of an underwater assault rifle were determined
