碰撞粒子 meaning in English
colliding particle
impingement particle
Examples
- The process is a purely diffractive process since no quantum numbers exchange between the two colliding particles
由于两个碰撞粒子之间没有量子数的交换，因此该过程是一个单纯的绕射过程。 - The integrands in the dispersion equation are not integrable in general , so we used the asymptotic expansion solution to analyze the behavior of the dispersion relation at the singularity and mapped the dispersion relation curves approximately the system composed of collisionless particles which obey maxwellian distribution or all kinds of degenerate distribution , even in their mixture system , their dispersion relation are analogous
一般来说，色散方程中的被积函数都是难以求积的，本文是用函数逼近法分析色散方程在奇点处的行为，并大致划出色散关系曲线。由无碰撞粒子组成的系统，不管初始分布是maxwell分布还是各种简并分布，甚至是这些分布的混合体，色散关系都是相似的。 - We have summarized a set of theoretical approach to this problem and discussed the instability of the gas cloud and the systems composed of collisionless particles in the background of dark matter . linear perturbation theory is the method to solve this problem , in which , we add the perturbation into the equilibrium state and discussed its evolution
本文研究了自引力系统的稳定性问题，总结了解决该问题的一套理论方法。并具体研究了存在暗物质背景时气体云和无碰撞粒子系统中扰动的演化情况。解决稳定性问题的方法用线性扰动理论，即在平衡态中加入扰动，研究扰动在系统中的演化情况。
