1·Now we will introduce what we call the average velocity.

下面我们引入，平均速度的概念。

2·Surprisingly, Jerry's average velocity is 54 HRS per iteration.

令人惊讶的是，Jerry的平均开发速率是每个迭代完成54个小时的工作量。

3·Will his average velocity help us to make correct iteration plan?

他的平均开发速率能够帮助我们制定准确的迭代计划吗？

4·And now we will look at the average velocity in a somewhat different way.

下面考虑下平均速度，方法就有些不同了。

5·The average velocity of droplet swarm is muchdiffrent from that of a single drop.

测试表明液滴群的浮升速度同单液滴有显著不同。

6·Notice that I haven't told you x It's completely unimportant for the average velocity.

这里请注意，我并没有说明,轴的原点在哪里。，where，I，choose，my，zero，on，my，x，axis。,因为它对平均速度而言,并不重要。

7·So the average speed 5m/s is 4.5 meters per second, 0 but the average velocity is zero.

因此平均速率,是4。,但是平均速度是。

8·Algal growth rate is different with average velocity, water depth and cross-section width.

藻类的生长速度因各断面的流速、水深和水面宽的不同而不同。

9·The technical difficult problem for automatic monitoring average velocity of flue gas was solved.

解决烟道烟气平均流速自动监测的技术难题。

10·Again, if I had changed the zero points you would have found the same values for the average velocity.

再强调一次，不管我这个0点选在哪里，这个平均速度的值，都是不会改变的。
