利用g - m型變質量天體軌道根數變化方程的一階和二階解對15個流星群軌道半長軸、近日點距離、軌道周期和近日點經度因太陽質量損失造成的每世紀的長期改變效應做了數值計算，並得出計算結果。 -
In view of the regression characteristic and the configuration maintenance demand of the regional coverage satellite constellation, the constellation configuration is optimized using the linear relations between the semi - major axis and inclination and the rates of change of the ascending node right ascension and phase, which enhance the long - term stability of the satellite constellation configuration, simultaneously the sub - stellar and the phase are controlled through changing the deviations of the semi - major axis and the inclination
摘要針對區域覆蓋衛星星座的回歸特性和構型維持需求，利用軌道半長軸和傾角與升交點赤經漂移和相位角漂移變化率之間的線性關系來優化星座構型參數，提高衛星星座構型的長期穩定性，同時通過協同控制軌道半長軸和傾角漂移量來實現區域覆蓋星座構型維持。 -
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
不同的引力勢模型對球狀星團軌道的具體形態影響不大，在給定的引力勢模型下，當某些星團的運動軌道穿越距銀心1kpc附近的區域時會出現「混沌」現象： （ 4 ） 29個樣本星團的軌道半長軸、遠銀心距和方位周期隨金屬度的變化規律基本相似，樣本星團的金屬度與其軌道形態之間的相關性並不明顯，然而軌道偏心率與金屬度有關，對于所選的暈族樣本星團而言，大約有24的樣本星團的軌道偏心率低於0 . 4 。 -
The results show that the solar mass - loss extends the semi - major axis, the distance at perihelion and orbital periods of the meteor streams, especially, the extensive influence on the semi - major axis is not overlooked, but this influence on other orbital elements may be neglected
其計算結果表明，太陽質量損失使流星群軌道半長軸每世紀的改變效應較明顯，它們同太陽距離的擴大影響值得關注，但對軌道周期的拉長每世紀的影響甚小，對近日點經度只有量級變化小到可以略而不計。 -
The different galactic gravitational potential have not clear influence upon the perigalactic distance, eccentricity and uncertainty of orbital parameters, but which is significant for other parameters, such as the apogalactic distance, semi - major axis, radial period and azimuth period and so on ; ( 5 ) the monte carlo simulation show that : the distribution morphologies of the orbital parameters which are produced by simulation data are separated into three types : gaussian profile, semi - gaussian profile and non - gaussian profile
不同的引力勢模型對近銀心距、偏心率和參數的不確定度等量影響較小，但是對遠銀心距、軌道半長軸、徑向周期和方位周期等參數影響較為明顯。 （ 5 ） montecarlo模擬的結果表明：根據模擬觀測數據得到的軌道參數的分佈形態大致可分為三類：高斯分佈、準高斯分佈和非高斯分佈；觀測數據對軌道參數的影響與樣本的選取、軌道參數的類型等有關。 -
