Using shape function andclassical interior ballistics theory, the influence relation of the PSS model parameter affectto splitting opportunity, increasing burning surface and interior ballistics characteristicswas researched.The splitting opportunity of PSS appears ahead the academic intending, thereason is that the thickness of outside burning layer is asymmetry, the thinner area splitsearlier, and the thicker area splits later, consequently, the PSS put up progressivity burningeffect. From the practical look, the burning progressivity effect is more profitable than thatincreasing burning surface suddenly.

采用形状函数和经典内弹道理论,研究了PSS发射药的药型参数对分裂时机、燃烧增面性和内弹道性能的影响关系,PSS发射药的分裂时机比理论预计值提前出现,原因是外侧面的燃烧层厚度不均匀,薄的地方先分裂,厚的地方晚分裂,从而表现出了渐增性的燃烧效果,从应用的角度出发,渐增性燃烧的效果比突增的效果要好。
