Furthermore, a new explanation to the characteristics of frozen orbit is presented.
在此基础上还对冻结轨道的性状作了新的解释。
In order to guarantee the characteristics of frozen orbit, in-plane orbit control needs to adjust the semi-major axis, eccentricity, argument of perigee simultaneously.
为了保证冻结轨道的冻结特性，平面内轨道控制需要对半长轴、偏心率和近地点幅角都控制。
On first blush, you might think not: the planet where the comet or comets came to grief is farther out than Mars, in an orbit where water would be permanently frozen.
一开始你可能不会这样认为，因为太阳系里和彗星发生过碰撞的行星都比火星还远，在那样的轨道上水永远是以冰的形式存在。
