And I claim that the answer should be positive because the vector field is crossing our paraboliod going upwards, going from the outside out and below to the inside and upside.

我相信结果应该是正的,因为向量场穿过我们的抛物面向上，从外部下面指向内部上面。

Well, it looks like positive should win because here the vector field is much larger than over there.

看上去正的会多一点,因为这里的向量场要大一些。

Speed is the magnitude of the velocity vector and the speed, therefore, always has a positive value.

速率是速度矢量的大小,因此速率一般，都是正值。

That OCZ managed to do so well with its first in-house controller is still a positive sign, and those willing to give the Vector a shot may find it worth the initial uncertainty.
