Maximize the time of flight and you point a cannon like this.
让飞行时间最大化,你像这样瞄准一门大炮。
They fit one distribution to the other, and when they line up that gives them the time of flight, and thus the speed.
他们拟合这两个分布,如果它们吻合则能给出飞行时间,因此飞行速度。
A program is established based on the Monte Carlo technique to simulate the time of flight spectrum in ion atom collisions.
基于蒙特卡罗方法,建立了程序模拟离子与原子碰撞中的反冲离子飞行时间谱。
It happened so early in the flight, at a level of about 900 meters, that the crew had little time to decide what to do.

It turns out to be-- there's a fairly complicated balance between the time of flight and the range.
答案表明,在飞行时间与射程之间,有着一个相当复杂的平衡关系
