他的平均开发速率能够帮助我们制定准确的迭代计划吗？
On average, a given team will tend to complete the same number of points' worth of work each iteration; this number is the team's velocity.
一般来看，稳定的团队会在每个迭代中完成固定点数的故事；这个点数就是团队的速度。
If the Angle is positive — - I call this a positive Angle — then the average velocity is positive but if I have a negative Angle then the average velocity would be negative.
如果角度为正的话…，这是我选的正方向-，那么平均速度也为正，可是如果角度为负，则平均速度也自然为负。
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。
So the signs in the velocity and the signs in average acceleration depend crucially on how I have defined my increasing value of x not where I choose my zero points.
所以速度的符号,和平均加速度的符号,这二者都取决于,这里x正方向,是如何定义的,和0点的选取没有关系。
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。
Now, I would think that it is reasonable to ask the following question: What is the average velocity, for instance, between time zero and time four?
现在，我认为,提出如下问题,是十分合理的：,比如说，平均速度是多少，在0到4秒之间？
We define average velocity as the position at time four seconds minus the position at time zero, 4 divided by four.
我们定义平均速度，是四秒时的位置，减去0秒时的位置，除以。
T5 For instance, between t4 and t5, if I draw this line then this Angle here is negative 5 and so the average velocity between t4 and t5 is now negative.
比如取t 4和，我这样连线，那角度就是负的，因此，t4和t5之间的平均速度5，为负。
The average acceleration 2 between time t1 and time t2 2 would then be the velocity at time t2 minus the velocity at time t1, divided by t2 minus t1.
在t1和t2之间的，这段平均加速度2，等于t2时刻的速度2，减去t 1时速度，再除以。
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。
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。
However, if you take the average acceleration t1 0 that is smaller than zero 0 because here the velocity is zero but here the velocity is negative.
可是如果考虑到,和t5之间的平均加速度5，between，t1，and，t5,那么它将小于,因为这里速度为,但是到了这里却是负值。
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。
The single most accurate way to estimate velocity on a project is to run several iterations and then see what the average velocity was.
在项目中最精确的估算速度的方法是，进行几个迭代，然后看看平均速度是多少。
Now we will introduce what we call the average velocity.
下面我们引入，平均速度的概念。
