In this dissertation, the design and optimization of lunar probe orbit has been studied by using the theory and method of spacecraft orbital dynamics, aiming at to launch polar moon satellite from the earth parking orbit, and considering synthetically the problems about the launcher energy, flying time, launch window and orbit navigation. The flying conditions, program and orbit of the lunar probe are given.

本论文利用航天器轨道动力学理论和方法，以从地球停泊轨道入轨点出发发射月球极月卫星的轨道为对象，综合考虑运载能力、飞行时间、发射窗口、轨道导航等问题，进行月球探测器轨道设计与优化，给出月球探测器的飞行条件、程序及其轨道。

Like the flying squirrels of America and Eurasia, the more distantly related flying scaly-tailed squirrels of Africa, and the marsupial gliders of Australia and New Guinea, colugos have a single large flap of skin, the patagium, which works a bit like a controlled parachute.

与美洲和欧亚大陆的飞行松鼠，以及与之关系更远的非洲飞行鳞尾狐猴、澳大利亚和新几内亚的有袋滑翔动物一样，猫猴有一个大大的、单独的皮肤翅膀——翼膜，翼膜的作用有点像可控制的降落伞。

The trajectory, or path, of a projectile is subject to the forces of gravity, drag, and lift.

外弹道学是研究射弹的飞行，弹道是射弹在重力、拖曳力和升力作用下的飞行路线。

ObjectiveTo investigate basic perceptibility in pilots and to analyze the difference of basic perceptibility of pilots served in different plane and so as to suggest more objective evidence for selecting pilot .

The research focuses on the flight of the pestilent locust, an insect renowned for its efficient flying style.

研究集中在蝗虫——这种以高效飞行方式出名的害虫——的飞行上。

By experimental study of the situation with high-velocity photogram, not only the initial speed and the decline law of it have been determined, but also many problems have been solved, such as the influence of choke on initial speed, the influence of wad on flying shots, the attitude change of flying wad, the process of the wad separated from the shots, and so on.

通过高速摄影实验研究，不仅较为准确地测出了初速大小和速度衰减规律，而且弄清了不同锥度的喉缩对初速的影响、弹托对弹子飞行的影响、弹托飞行姿态的变化特点及弹托脱离弹子的过程等问题。
