速度弥散 meaning in English

velocity dispersion

Velocity dispersion method
速度弥散度方法
First , we investigate the feasibility of determining the pairwise velocity dispersion ( pvd ) for lyman break galaxies , and of using this quantity as a discriminator among theoretical models
本文探讨了对lymanbreak星系的对速度弥散( pvd )进行测量以及用该量来约束理论模型的可行性。
Given the initial conditions including ( 1 ) number density distribution in space which has the similar form to the present day ones , ( 2 ) both the power law and gaussian mass functions for clusters , and ( 3 ) two different velocity distributions which one has a constant dispersion and the other is described by the eddington formula , the dynamical evolution of globular clusters in our milky way galaxy is investigated in detail by means of monte carlo simulations
本文采用与观测结果具有相同形式的球状星团空间密度分布函数，在给定两种球状星团系统的初始质量谱(幂律的和对数高斯的)和两种球状星团系统的初始速度分布函数(爱丁顿速度分布函数和常数的速度弥散度)条件下，我们采用montecarlo的方法对球状星团系统的动力学演化进行讨论。
