子弹时间(Bullet time)是一种使用在电影、电视广告或电脑游戏中,用计算机辅助的摄影技术模拟变速特效,例如强化的慢镜头、时间静止等效果。它的特点是不但在时间上极端变化(观众可以看到一些在平常不能见到的景象,如子弹飞过头顶,因此得名),而且在空间上极端变化:在慢镜头的同时拍摄角度(观众视角)也围绕场景旋转。
这些实验的结论为,子弹达到了2750米(9000尺)远,上升时间为19秒,下降时间则几乎有上升的两倍长——36秒。
The conclusion from the experiments was that the bullets reached 2, 750 metres (9, 000ft), taking 19 seconds to rise and almost twice as long - 36 seconds - to fall.
这条1300公里长的高速铁路线预计将两个城市之间旅行时间裁减到约五个小时,每天有90对子弹头列车运行。
The 1300-kilometer-long high-speed rail line is expected to cut travel time between the two cities to about five hours, with 90 pairs of bullet trains operating each day.
结果表明,由配用可编程电子时间引信的侵彻子弹毁伤效果满足跑道未受损面积设计要求。
The result indicates that the damage effect of penetration submunition equipping the programmable electron time fuze meet the design requirement of undamaged areas of aerodrome runway.
