查询词典 progressivity

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。

One may regard this as another form of subsidy, since taxes occur later in life and usually at a lower rate due to progressivity.

人们可能认为这作为另一种形式的资助，后来因为发生在税生活（因此，一个隐含的税收抵免），通常在较低由于累进税率。

The new law sharply reduces progressivity but aims to restore confidence in the system by eliminating inequities.

新法大大减少了累进层次，但通过消除不公平现象恢复了人们对税制的信心。

明显地，税收系统很大地变化在他们的程度progressivity，并且调动的分派可能或多或少歪曲往低收入小组。

Greater progressivity in income taxes is one mechanism; at relatively early stages of development, however, those taxes remain quite imperfect and may deed to be complemented by luxury taxes on large apartments and cars.

提高个人所得税的累进税率便是一种解决办法；然而，在这种税制尚未完善之前，可以对大面积公寓和汽车等征收奢侈品税。

In the interest of seeking the essential principle and technique about how to enhancethe muzzle velocity of projectile, preparation technics and fundamental characterstics ofprogrammed splitting stick propellants and polyether polyurethane close-grainedpropellants, this two kinds of high progressivity burning and high charging densitypropellants, were researched in this paper.
