摘要： 基于Ｂｒｏｕｗｅｒ平根数的概念研究了冻结轨道，发现了这样一个事实：如果用Ｂｒｏｕｗｅｒ平根数来表示冻结轨道，则该平根数对应的轨道恰是一条精确的圆轨道。在此基础上还对冻结轨道的性状作了新的解释。此外还针对只包含二阶和三阶带谐调和项的地球引力场内的冻结轨道偏心率在临界倾角附近的性状作了分析，显示出临界倾角附近轨道的异常性状在这个低阶的引力场内仍未改变。

Abstract: In this paper frozen orbit is investigated based on Brouwer's mean orbit elements .It has been found that the orbit elements of frozen orbit describe an exact circular orbit.Furthermore,a new explanation to the characteristics of frozen orbit is presented.In addition,the variations of orbit eccentricity corresponding to the changes of orbit inclination is analyzed under the earth gravitational field including only J 2 and J 3.It can be seen that the abnormal behavior near critical inclination is still kept.
