His curveball's hump is absolutely tiny and he is letting it go from exactly the same release point. 曲球的隆起幅度非常的微小,并且与快速球的出手点几乎相同。
None of my colleagues looked alarmed, so I trained my viewfinder on the release point. 我的同事们没有感到不安,所以我瞄准了相机镜头的拍摄点。
Again the release point, good or bad, can be traced to the quality of the push away. 再说一次,推球的质素会影响释球点的好坏。
Substantial and rapid rotation when the last hard, make the discus in the shot moment to get the most out of the shot speed and provides a foundation to ensure a higher release point for a good throw results. 在最后用力时的大幅度快速旋转,能使铁饼在出手时刻获得最大的出手速度,较高的出手点为好的投掷成绩提供了基础保证。
In this paper, the regulars of the draw-out-time with the height of the release point and the flying speed of aircraft has been analysed by founding the mathematical model of the parachute drawing out and the simulant calculation. 通过建立减速伞拉直过程的数学模型,利用计算机编程模拟计算,分析了拉直时间随投弹高度和飞机航速的变化规律。
