Dynamical evolution of spatial bright solitions in cogarithmically nonlinear electric media under weak amplitude condition was studied 摘要研究了對(duì)數(shù)型非線性電介質(zhì)中低振幅空間明孤子的動(dòng)態(tài)演化特性。
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 本文采用與觀測(cè)結(jié)果具有相同形式的球狀星團(tuán)空間密度分布函數(shù),在給定兩種球狀星團(tuán)系統(tǒng)的初始質(zhì)量譜(冪律的和對(duì)數(shù)高斯的)和兩種球狀星團(tuán)系統(tǒng)的初始速度分布函數(shù)(愛(ài)丁頓速度分布函數(shù)和常數(shù)的速度彌散度)條件下,我們采用montecarlo的方法對(duì)球狀星團(tuán)系統(tǒng)的動(dòng)力學(xué)演化進(jìn)行討論。
