势平衡理论的初速或然误差的模拟方法,建立在火药动静态燃烧的不均一性参量π与π’成正比,即π=θπ’的物理推断的基础上.该文通过三种七孔药的动静态燃烧试验,验证了该推断的正确性,并证实了火药的初速或然误差与其动静态燃烧的不均一性参量π、π’成正比的规律. Based on the physical inference of the heterogeneous parameter π of the static and dynamic combustion of gunpowder, which is proportional to π ’, that is, π = θπ’ The dynamic and static combustion tests verify the correctness of the inference and confirm the law that the initial velocity error of gunpowder is proportional to the heterogeneous parameter π, π ’of dynamic and static combustion.
