So if we now look at this plot we can search for The Times that the velocity is zero so you have to look for the derivative being zero.
我们观察一下这个图像，就可以找到，速度为0的时刻，因此只需要观察，导数为0的情况。

Our contribution to the search for this "missing matter" has been to study the rotational velocity of galaxies at various distances from their center of rotation.
