摘　　要：该文在火炮、装填条件、点火系统及测试条件控制严格一致条件下，各火药批的初速或然误差呈现出有规律变化的实践基础上，从理论方面论述了由火药本身燃烧不均一性所引起的初速散布与其在密闭爆发器中的燃烧特征之间具有一定的关系，从而得到应用密闭爆发器来预估初速或然误差的工程方法，并应用实际射击试验数据加以验证。Under strictly consistent gun,charge loading,igniting,test control,and regular changes of the probable errors of muzzle velocity of each propellant batch,this paper theoretically expounds the relation between the dispersion of muzzle velooity caused by the nonhomogeneity of propellant burning and the characteristics of propellant burning in closed bomb so as to obtain the engineering method for predicting and estimating the probable errors of muzzle velocity in the closed bomb.And finally the method is verified through practical test data of shooting.
