那部分是数学的东西，即散度定理。

At that part is actually math, namely, the divergence theorem.

youdao

梯度和散度是完全不同的东西。

OK, so divergence and gradients are completely different things.

youdao

取一个向量场的散度。

OK, so you take the divergence of a vector field.

youdao

我们想求出它的散度。

So, now, we want to take the divergence of this.

youdao

在某种方式下它们是有联系的,这就是散度定理。

OK, so we have somehow a connection between these which is the divergence theorem.

youdao

那就是散度。

That's divergence.

得到了一类二阶散度型椭圆方程很弱解的一个正则性结果。

A regularity result of a class of second order divergence form elliptic equation was obtained.
