orbital eccentricity meaning in Chinese
道心率
轨道的圆度
轨道离心率
轨道偏心率
偏心率
Examples
- As ba star systems are evolved from g - k star systems , the distribution of orbital eccentricities and periods of ba stars can show the final orbital character of binaries
由于钡星系统是由普通红巨星双星系统演化而来,因此钡星系统的轨道偏心率及周期的分布显示了经过质量吸积后双星系统的最终轨道特征。 - The differences in orbital morphologies due to different potentials is slighting , however , given a certain potential , for clusters that have perigalactic distance smaller than 1 kpc , some orbits may exhibit a chaotic behavior . the correlation between the metallicity of samples and the orbital morphologies is unclearly ; ( 4 ) it is found that the semi - major axis , apogalactic distance and azimuth period of 29 sample clusters are changed with their metallicity similarly , but a obvious correlation is seen between orbital eccentricity and metallicity . there is a fraction of 24 % of the sample clusters with eccentricities lower than 0 . 4
不同的引力势模型对球状星团轨道的具体形态影响不大,在给定的引力势模型下,当某些星团的运动轨道穿越距银心1kpc附近的区域时会出现“混沌”现象: ( 4 ) 29个样本星团的轨道半长轴、远银心距和方位周期随金属度的变化规律基本相似,样本星团的金属度与其轨道形态之间的相关性并不明显,然而轨道偏心率与金属度有关,对于所选的晕族样本星团而言,大约有24的样本星团的轨道偏心率低于0 . 4 。 - Our results show that , during the evolution of a binary system , the system widens as it loses mass , and the orbital period increase , while orbital eccentricity remains nearly constant , which can explain the distribution regulation of orbital elements of normal g - k giant and barium stars and the distribution character of the heavy - element abundances of barium stars
计算结果表明,随着星风吸积过程的进行,在星风质量损失阶段系统轨道半长轴将增大,导致轨道周期增大,而偏心率变化不大,由此可以解释普通红巨星双星系统和钡星系统的轨道根数的分布规律和变化情况以及钡星重元素丰度分布特征。
