midcourse trajectory

When solving required velocity,It real-timely thinks about influence of oblateness of the earth and gives the process of solving required velocity by midcourse trajectory method.

求解需要速度时,实时地考虑了地球扁率的影响,并给出了利用中间轨道法求解需要速度的过程。

This paper discusses the properties of shift maps on the set of periodic points within the orbit space and the inverse limit space.

讨论了轨道空间和逆极限空间上移位映射在周期点集上的性质,即等度连续性和局部度量不稳定,证明了以下结论:如果坐标映射在周期点集上具有等度连续性,则移位映射在周期点集上具有等度连续性;如果移位映射在周期点集上具有局部度量不稳定性,则坐标映射在周期点集上具有局部度量不稳定性。
