speed is measured in kilometers or miles per hour . For example , a speed of 16 kilometers( 10 mi ) per hour means that something is moving fast enough to travel 16 kilometersin one hour . This speed is recorded as 16 kph( 10 mph ) . Speed can also...
A new-generation bullet train that will travel up to 380 kilometers per hour (kph) is now under development for the high-speed rail link. It will be rigorously tested this year, and engineers want the train to run at a top speed of 420 kph to guarantee a safe operational speed of ...
The driverless "bullet trains" connecting Beijing and Zhangjiakou in northern Hebei Province are capable of hitting speeds up to 350 kph,making them the world's fastest autonomous trains.(1)What can we know about Chinese railway in the past? A...
BEIJING, Feb. 26 (Xinhua) -- China is developing new bullet trains with a speed up to 400 kph, said a leading figure in the country's high-speed railway technology development. Ding Rongjun, an academician of the Chinese Academy of Engineering, said that China was also researching the next...
在日常用语中，这两个词没有区别，可以通用。而在物理学里，velocity 是一个矢量(vector quantity)表示起点与终点间直线距离的长度除以所用时间所得的量，并注明方向：而 speed 是一个数量(scalar quantity)，是指起点到终点所走过的所有路程除以所用时间所得的量，且不标明方向。
BEIJING, Sept. 21 (Xinhua) -- China Thursday increased the maximum speed of bullet trains on the Beijing-Shanghai high-speed railway to 350 kph, making it once again the world's fastest train service some six years after it was reduced to 300 kph. ...
