摘要： 将 Brouwer早期研究所获得的一阶解变换为适用于小偏心率轨道的结果 ,根据这个结果可以清楚地看出冻结轨道就是精确的圆轨道 ,冻结的特性及其机理也可以清楚地显示出来。此外还进一步采用 Hill变量将冻结轨道的一阶解表示成一种非常简单的形式。

Abstract: Based on the first order solution of Brouwer's theory for artificial satellite orbit, formulas suitable for near circular orbit are derived. From the formation it is obvious that the frozen orbit is the exact circular one. The feature and the cause of the frozen orbit are easily explained. In addition, a very simple solution for the frozen orbit is also presented by using Hill variables.
