Well, , see, that is a vector field that is equal to the vector from the origin to the point where I am, so it is pointing radially away from the origin.
也就是，这个向量场等价于,从原点指向给定位置的向量，所以它是以原点为心向外辐射的。
I'm going to prove that the flux of a vector field that has only a z component is actually equal to the triple integral of, RzdV well, the divergence of this is just R sub z dV.

So, one of them says the line integral for the work done by a vector field along a closed curve counterclockwise is equal to the double integral of a curl of a field over the enclosed region.
其中一种说明了，在向量场上，沿逆时针方向，向量做的功等于，平面区域上旋度F的二重积分。
r So, let's remember that the amount by which we moved, t delta r, is approximately equal to v times delta t, OK, and just using the definition of a velocity vector.
所以记住移动的量△,约等于v*△,这是用速度矢量的定义。
Only if the component vectors are on a straight line will the length of the vector for the sum be equal to the sum of the lengths of these components or to their difference.
只有当几个分矢量在一直线上，那么表示其和的矢量长度才会等于这些分量的长度和或它们的差。
Only if the ponent vectors are on a straight line will the length of the vector for the sum be equal to the sum of the lengths of these ponents or to their difference.
只有当几个分矢量在一直线上，那么表示其和的矢量长度才会等于这些分量的长度和或它们的差。
The change in the momentum of a system of particles during an impact is equal to the vector sum of all the external impulses acting on the system.
碰撞时质点系动量的改变等于作用在质点系上所有外碰撞冲量的矢量和。
The generalization error of Support Vector Machine is approximately equal to that of Probabilistic Neural Network. And Support Vector Machine is easier to use than Neural Networks.
支持向量机的分类误差与概率神经网络相近，但支持向量机的使用较概率神经网络简单。
When the output vector dimensions equal to the input vector dimensions, the necessary and sufficient conditions for decoupling and complete linearization to nonlinear system are given.
