What's more, China is working on the new high speed trains with the highest speed of 400km/h.
更重要的是,中国正在研制最高时速400公里的新型高速列车。
Its speed is 120 km/h, having more stops than the T trains.
它的速度是每小时120公里,比直达快车有更多的站点。
How many kinds of trains are there whose speed reaches 250 km/h and above?
时速达到250公里以上的火车有多少种?
So, since the speed of light equals lambda nu, we can say that momentum is equal to h divided by lambda.
所以,既然光速等于λ乘以υ,我们可以得到动量等于h除以λ
