Then we analyzed the change process of trajectory in air - to - ground missile attack , built the movement equations based on the center of gravity of every segment . in the end we gave the whole trajectory simulation result of air - to - ground attack
分析了空地导弹攻击的弹道变化过程，将攻击过程划分为五部分，分别对各段建立了重心运动方程并进行了仿真，最后给出了空地导弹攻击的全过程弹道仿真结果。
To further the study of the take - off technical theory in the backstyle high - jump , we make a research into the cuved tosbury take - off cour se of backstyle high - jump . it was pointed out that the backtyle high - jump cucve d run take - off created efficient condition for the earlier change and accumla tion of gravity center and vertical speed of fosbury flop the moving direction t he bady
为进一步研究背越式跳高起跳理论，对背越式跳高弧线助跑起跳过程进行分析，揭示背越式跳高的优越性在于充分发挥和利用助跑速度提高起跳效果，其实质是弧线助跑起跳为背越式跳高身体重心运动方向的提早转变和垂直速度的累积创造了有利条件。
