There is no curl. This is not what curl measures.
这个场里没有旋度，旋度是不度量拉伸之类的东西的。
That other field is given from the first one just by taking its curl So, after you take the curl, you obtain a different vector field.
另一个向量场，是通过计算第一个向量场的旋度得到的，计算旋度之后，就可以得到一个不同的向量场。
Now, an important difference between curl here and curl in the plane is that now the curl of a vector field is again a vector field.
和平面上的旋度的一个重要的不同点是，这里向量场的旋度，仍然是一个向量场。
And that is indeed going to be the curl of F. in practice, if you have to compute the curl of a vector field, you know, don't try to remember this formula.
这就是F的旋度，在实际应用中，如果你必须计算一个向量场的旋度，不要尝试记忆这个公式。
The calculation of this thing, once you've computed curl does not remember that it was a curl.
当你计算这个式子时，不要把它当做旋度来算。
I mean, we said for curl, curl measures how much things are rotating somehow. What does divergence mean?
我们知道旋度是度量旋转的，那散度表示什么？
Unix-based operating systems include curl by default, and you can download free curl utilities for other OSes.

Note: to see the request that cURL makes, add the -v switch (for verbose output), which makes the request but also returns any HTTP request that cURL makes to fetch the result.
注意：若要看到cURL发出的请求，可以添加- v开关(详细输出)，这样不仅会发出请求，而且会返回cURL发出的用于获取结果的任何HTTP请求。
The cURL utility has so many options, it's best to read over its lengthy man page. Here are some common cURL uses

After creating each individual curl and removing the iron, re-roll curl around fingers to recreate the curl.
每个人在创建卷曲，去除铁，再卷卷曲手指周围重新创建卷曲。
