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 contents and original points of view are as follows : 1. the complete depth - averaged tubulence model is adopted to compare with the tradional depth - averaged model. the non - uniformity of velocity in z axis is considered in the former. the rigid - lid assumption, which was adopted for long time, is discarded, while the transpot equation of kinetic energy of dispersion is introduced. the 2d term ' s distribution of space - time is calculated
論文包含的主要內容及創新點有： 1 、引進了完全深度平均紊流模型，與傳統深度平均紊流模型相比，該模型計入了流速在深度方向分佈不均勻的影響；去掉了深度平均紊流計算中長期採用的「剛蓋假定」 ，同時模型通過引進離散動能的輸運方程，計算了二維離散項的時空分佈。
