大气圈中的任一层

The space ship flies into the sky and flies through the aerosphere.

宇宙飞船直上九霄,最后飞离了大气层.

During the climbing phase, the parameters, such as weight, center of weight, altitude and velocity of a trans- aerosphere vehicle changed so much so that its control and stability also change so much.

跨大气层飞行器在爬升过程中重量、重心、高度和速度等参数变化剧烈，因而飞行器的操纵稳定特性也变化急剧，与常规飞行器相比其飞行控制律设计有它的特殊性。
