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.

If you take a vector field that is a constant vector field where everything just translates then there is no divergence involved because the derivatives will be zero.
如果取的向量场是处处恒定的，所有点都是平移关系，所以没有散度，因为导数为零。
OK, so, we've seen that if we have a vector field defined in a simply connected region, and its curl is zero, then it's a gradient field, and the line integral is path independent.
一个向量场,如果定义在单连通区域并且旋度为零，那么它就是一个梯度场，并且其上的线积分与路径无关。
OK, so let's assume that we have a vector field whose curl is zero.
假设有一个旋度为零的向量场。

Enter zero model sync into the Enter a zero command text field, then click the green Enter button.
将zeromodelsync输入Entera zerocommandtext字段，然后单击绿色的Enter按钮。
So if you've done the problem sets and found the same answers that I did, 0 then you will have found that this vector field had curve zero everywhere.
如果你们做了习题集,发现了和我一样的答案，你就会发现向量场的旋度在曲线上处处为。
Enter ./zero/forms/rsvp.json into the Relative URI to form model file: field.
在RelativeURItoformmodelfile:字段中输入./zero/forms/rsvp.json。
If the curl is zero, and if the field is defined everywhere, then it's going to be conservative.
如果旋度为0，而且场处处有定义，那么它就是保守场。
The third field is an environment pointer for languages that use one, but is normally just set to zero.
第三个域是语言的一个环境指针(如果该语言使用了环境指针的话)，不过通常都会被设置为0。
The test that we saw last time saying, well, to check if something is a gradient field if it's conservative, 0 we just have to compute the curl and check whether it's zero.
由上次的测试可知，如果一个东西是保守的，要确定是不是梯度，我们只需要计算旋度，查看它是否是。
If the number of iterations is zero, it means the statement was never executed. If however the number of iterations field is empty it means one of four things.
如果迭代次数为零，就表示从不执行该语句。
