轨道偏心率 meaning in Chinese
orbital eccentricity
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 。 - Comparing with the current observations , which include the number density distribution in space , mass function , etc . , the so - called standard modes for both the power law and gaussian cluster initial mass functions are selected among many runs of simulations . the deviation from the standard modes , which is resulted from the change of the parameter for the initial conditions , is discussed in detail . the discussion of the model parameters is also presented although they are adopted as the typical values based on previous work
对应一定的初始分布我们发现无论是幂律的还是对数高斯的球状星团初始质量谱经过长时间的动力学演化都会得到和现在银河系观测到的球状星团系统相符的对数高斯的质量分布；动力学演化会明显地改变球状星团系统的空间密度分布，靠近银心区域的球状星团瓦解得更多；经过动力学演化后的球状星团速度分布函数在靠近银心的区域明显得不同于初始分布，初始拥有较大轨道偏心率的球状星团更容易瓦解。 - This method offers more precise geometry for spaceborne sar system design and simulation . 3 . in the analyzing on the radar doppler properties , under the ellipsoid earth model and ellipse orbit model , considering the earth rotation , the radar doppler properties with different orbit eccentricity are compared , and the fact that orbit eccentricity affects doppler frequency rate is found
