将高速滑体制成相似的机翼模型，进行风洞试验，即可测定滑坡凌空飞行的空气动力学参数，从而计算大型高速滑坡凌空飞行的空气动力升力、飞行速度和飞行距离等。
If we make a wing model which is similar to sliding mass, we can determine aerodynamic parameters by the wind tunnel testing and thus calculate the lift.
在空气动力学上，升力是重量，推力和阻力(空气阻力)的相关的函数。
In aerodynamic terms, lift is a function of weight, thrust and drag (air resistance).
由于地处高海拔地区，气压较低，因而作用在球上的阻力及升力所产生的空气动力效应也会发生相应反应，最终导致球在空中飞行速度比在低海拔地区快，飞行的路线也更直。
At altitude, the air pressure is lower, and so are aerodynamic effects such as drag and lift, ultimately causing balls to travel faster and straighter than they would at lower altitude.
