timer

That timer will keep timing the whole time the bullet flies through the air right up until our bullet hits the target, crossing through the same type of piece of paper with foil on both sides, closing a switch connection, telling our timer to stop timing, and giving us an exact time of flight of the bullet from the rifle to the target.

计时器会一直走表 记录下子弹飞行所用的全部时间 直到子弹击中目标 子弹将穿透同样一张双面贴箔的纸 从而关闭电路 停止计时 便可准确得出 子弹从出膛至击中目标 在空中飞行的时间
