碰撞效应 meaning in English
collision effect
Examples
- Yinggete - bagemaode metamorphic core complex belt with three - layer construction is put forward , which evolved from late jurassic to cretaceous . the extensional simple shear model of the chagan fault depression is established . the tectonic evolution and the dynamics character of chagan fault depression and its adjacent mesozoic - cenozoic basins are discussed : at the end of triassic continental orogeny increased crust thickness crust uplift and denudation were happened ; jurassic was a period of local partly extensional collapse of erogenic belt and cretaceous was a period of widely extensional collapse of postorogenic erogenic belt ; cenozoic was a period of the development of stable intracontinental depression with the character of long distant collision response and weaked compression flexure
讨论了查干凹陷及邻区中-新生代盆地构造演化及其地球动力学特征，三叠纪(印支期)为陆内造山作用与地壳增厚、隆升剥蚀阶段；侏罗纪(燕山早期)为造山后造山带的局部伸展垮塌阶段；白垩纪(燕山晚期)为造山期后大规模伸展垮塌作用与伸展盆地的发育阶段；新生代(喜山期)为远距离碰撞效应与弱挤压挠曲性质的稳定大陆内坳陷的发育阶段。 - First , we extended the liberman model of collisionless rf sheath . taking into account elastic collisions and charge - exchange collisions between ions and neutral particles , we established a self - consistent model describing the dynamics of rf sheath driven by a sinusoidal current source . the effects of collisions and rf - biased source power on the instantaneous thickness of the rf sheath and the sheath electric fields were studied
首先将liberman的无碰撞射频鞘层模型进行推广，考虑了离子与中性粒子的电荷交换碰撞效应，建立了描述碰撞射频等离子体鞘层动力学特性的自洽模型，研究了碰撞效应，射频偏压，电源参数等对射频鞘层的瞬时厚度及电场分布的影响。 - Second , monte - carlo method is used to simulate the transports of ions penetrating through the rf sheath in terms of the above sheath dynamic model . here , both elastic collisions and charge - exchange collisions between ions and neutral particles are considered . the effects of collisions on the distributions of ions energy and angle incident on the substrate were calculated
其次，利用已建立的碰撞等离子体鞘层模型和monte - carlo方法模拟了离子在射频鞘层电场中的运动过程，不仅考虑了离子同中性粒子的电荷交换碰撞，还考虑了它们之间的弹性碰撞过程，研究了碰撞效应对入射到基板上的离子能量分布和角度分布的影响。 - The first aspect is about the distribution function for fermions in quasi - equilibrium qgp which is perturbed by the fluctuation of the color field . neglecting the affect of the spin and the collision between the particles in qgp , the distribution function for fermions in quasi - equilibrium qgp has been obtained . further more , the physical " basses that decide the departure factor are analyzed
第一，从qgp动力论出发，忽略自旋和碰撞效应，得到qgp在色场涨落扰动下偏离平衡态而处于近平衡时的分布函数的二级近似以及偏离因子的物理表示，进而分析了决定偏离因子的物理因素。
