特别地,一个没有旋度的力场,就是一个不产生任何旋转运动的力场。
In particular, a force field with no curl is a force field that does not generate any rotation motion.
关于旋度的更多介绍,设有一速度场,我们知道旋度是测量旋转影响的。
More about curl.If we have a velocity field, then we have seen that the curl measures the rotation affects.
旋度会计算出,发生了多大的旋转。
And the curl will compute how much rotation is taking place.
It doesn't simply orbit the nucleus, but as it orbits it spins.
它并不只是简单地绕原子核旋转,而是同时进行公转和自旋。
