今天早些时候< <美国石化信息周刊> >上发表了一篇文章指出科威特的国营科威特石油公司（ kpc ）并没有提供其石油储备量的真实情况。 - 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 。 - The calculating results show : ( 1 ) most of samples are located in 5 kpc - 10 kpc from galactic center . all of the sample clusters present a spherical symmetrical distribution around the galactic center , and their space velocities are presented a ellipsoidal distribution ; ( 2 ) according to the metallicity and basic characters , the sample clusters are separated into hb subgroup and mp subgroup . the number of samples are changed with metallicity [ fe / h ] , and there is a peak at [ fe / h ] = - 1 . 6 ; ( 3 ) the orbits of sample clusters show mostly limited , periodic characteristics , but the orbits are not closed completely , their maximal galactocentric distance is less than 40 kpc
计算结果表明： ( 1 )大部分样本星团都位于银心距5kpc 10kpc的范围内，相对于银心呈球对称分布，它们的速度也呈椭球分布； ( 2 ) 29个样本星团按其金属度大小和基本性质分类，可分属hb和mp两个球状星团次系，且样本星团数随金属度[ fe h ]而变化，在[ fe h ] = - 1 . 6处出现一个峰值； ( 3 )所有样本星团的轨道运动都呈周期性，大都在一个有界而不封闭的周期轨道上运动，其最大银心距都在40kpc以内。
