• 2.Well, we've seen this criterion that if a curl of the vector field is zero and it's defined in the entire plane, then the vector field is conservative, and it's a gradient field.
  我们已经知道了一个准则，如果向量场的旋度为零，而且它在整个平面上有定义，那么这个向量场是保守的，而且它是个梯度场。

• 3.OK, so the first property that I will have for a vector field is that it's conservative.
  第一个性质是有一个向量场,它是保守的。
