      用法和例句

      Then the formula of relation between light-wavelength change and tangential and radial velocity of light source is presented and the conclusions listed below are reached: (1)The light-wavelength change is determined together by tangential and radial velocity of light source; (2)Doppler effect is a special case of above-mentioned formula, (3)When the radi.

      采用速度矢量分析法,揭示了絕對光速、相對光速和光源速度的關系,給出了光波波長變化與光源的切向速度和視向速度的關系式,并得出如下結論:(1)光波波長的變化由光源的切向速度和視向速度共同決定;(2)多普勒效應是上述關系式的一個特例;(3)當光源的視向速度為0時,光波波長的變化完全由光源的切向速度決定,其切向速度越大,光波的波長越短;(4)當光源的切向速度和視向速度都不為0時,在一定條件下光波波長不變。

      On the basis of radial velocity membership determination method, while the distribution of surface-number-density of galaxies in cluster regions is concerned s imultaneously, we calculate the distribution parameters and membership probabilities of individual galaxies for 8 Abell clusters.

      本文利用在考慮團內星系面數密度分布的前提下,以視向速度為判據,按最大似然原理解算團分布參數和成員概率的嚴格統計方法,對8個Abell星系團進行了成員研究。

      The line-of-sight velocity distributions (LOSVDs), including velocity dispersions, velocity distributions profile and redshift, are the important observational constraints in our understanding of the galactic dynamics, structures and evolution, as well as the nature of supermassive black holes in the center of galaxies.

      星系的恒星視向速度分布是星系動力學模型的重要觀測約束,其特征參數包括速度彌散度、分布輪廓以及紅移。
