screen velocity的意思|示意

They're different because they don't exist behind a screen; they're in our world, built from real physics, not simulations, they have mass and velocity and smell.

他们的与众不同之处在于他们不存在于屏幕里面，他们就活生生地存在在我们的世界里，是被真实的物体组成的，而不是模拟，他们有重量、速度和气味。

A novel Laser screen velocity measuring method with large effective screen area is introduced for some special velocity measuring occasions like wide spreading range or big-size flying objects.

针对弹道散布范围大或被测飞行物体尺寸大的测速场合，介绍了一种实现大面积有效靶区激光光幕速度测量的方法。

Because of drawback of four-screen measuring system and two-screen velocity measuring method, an improved six-light-screen array is presented that is composed of six large area light screens.

弹丸着靶坐标和飞行速度以及飞行方向角是外弹道测试中必测参数，本文针对四幕光幕靶和双光幕测速系统的不足，采用六个大靶面光幕靶，构造出了两类六光幕阵列结构。
