Therefore, if an airplane takes off on inclined plate and gets the best Take-off performance, the aerodynamic characteristic and up-warping Angle of inclined plate should be considered.

因此，实际情况中要使飞机在斜板上起飞时达到最好的起飞性能，需要综合考虑飞机的气动力性能和斜板上翘角度的影响。

Therefore, athletes should be a smooth run-up in the game, off to a strong and decisive, take-off angle should be appropriate and have a certain altitude;

因此，运动员在比赛时助跑应平稳，起跳要果断有力，起跳角度要恰当，并具有一定高度；
