此后，为了代替退役电站，新电站必须以相同速度建造才可以。

After that, new plants would need to keep being built at the same pace just to replace retiring ones.

雪橇将以相同速度进行直线运动，除非它受到同样大小的力而被影响。

So the sledge will just keep going in a straight line at the same speed unless its acted upon by the same force.

For example, if you started here and you did all this and you came back here, the average velocity would be zero, because you start and end at the same value of x, you get something; 0 divided by time will still be 0.

例如,如果你从这里开始运动,经过这个过程又回到这里,平均速度就是0,因为初态和末态的位移相同,你得到了什么呢,0除以时间还是0
