摘　　要：确定了表征水下弹丸运动性能的参数——存速系数,并利用该参数从工程应用角度出发,探讨简化水下弹丸威力试验的2种方法,一是建立水下弹丸在不同水深下运动性能的试验模型,以浅水实验代替深水实验;二是从水下弹丸的威力指标出发,找出不同水深中最难满足的弹丸威力指标(不妨称之为最严格指标),只需对该单项指标进行考核,文中最后经实弹实验,验证了该方法的可行性。Velocity-hold coefficient-the parameter for charactering the moving property of underwater bullet Was decided. Using this coefficient, grounded on engineering application, tow method for simplifying the experiment of underwater bullet power was discussed. One is establishing the model for testing the moving property of underwater bullet in different water depth, and that in deep water was replaced by the experiment in shallow water. Another is staring from the power index of underwater bullet. the rigorist index was found and tested to represented others. In addition, the method was proved to be feasibility by experiment.
