  • It's not a gradient.

    不是梯度

    youdao

  • So, indeed, this is not a gradient field.

    因此不是一个梯度

    youdao

    现在我们来看看梯度第一性质

    youdao

  • We have said if we have a gradient field then we have this.

    如果一个梯度得到这个

    youdao

  • So, if you prefer, that's where the gradient vector is zero.

    认为梯度向量零也是可以的。

    youdao
