Mechanical properties and combusition characteristics were affected evidently by the solid grain configuration and its character. Mechanical propertiesof the material system could be improved by adopting RDX and proper granularpropellants granularity rank-match. It is favorable to obtain progressivity burning effect byaffiliating increasing burning surface propellant grains. Affiliating fast burning componentthese burning rate regulator in the bond system can quicken burning rate of propellants andimprove burning progressivity.

固体颗粒形态及其性质对力学性能和燃烧性能具有较大的影响，采用RDX与适当颗粒度的固体发射药的粒度级配有利于改善力学性能，加入增面燃烧的发射药颗粒，有利于获得渐增性的燃烧效果，在粘合剂体系中加入速燃组份等燃速调节剂，可加快发射药的燃气生成速率，改善燃烧的渐增性。

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。

Tax progressivity is often at odds with efficiency.

税收系统的先进性往往是和高效性相矛盾的。

progressivity：累进性

第三,美国税法一个重要的原则就是所谓的累进性(progressivity). 税负随所得的上升而上升,换句话说就是指纳税人的所得越高,其平均税率就越高. 为达到这一目的,美国联邦所得税一直采用累进边际税率结构,将所得划分为不同的等级,
