数个镜像单元为一组，被固定在一个随太阳全天轨迹而移动的追踪仪器上。

Several mirrored units are placed together on a panel, which is mounted on a tracking apparatus to follow the sun throughout the day.

以轨道半径和轨道倾角为未知量依据星下点轨迹要求条件构建了非线性方程组，但直接求解过于复杂，采取迭代的方法解决。

Non-linear equations are(constructed) with the restriction of the satellite ground trace to resolve the unknown semi-axis and inclination, but it's too complicated to be resolved directly.

其次分析这些模型特性，找出六组典型运动轨迹与初始条件的关系；

The dynamic characteristics of this model are analysed. Relations between motion trajectory and initial conditions have been found.
