tangent vector field

常見(jiàn)例句

That is how we reformulated it. That means we take our curve and we figure out at each point how big the tangent component I guess I should probably take the same vector field as before.
這是另一種形式，它意味著,要求出每點(diǎn)處向量在切向量方向的分量,我還是用之前那個(gè)向量場(chǎng)吧。
In particular, an easy case where you know you can get away without computing anything is, of course, if your vector field is tangent to the surface because then you know that there is no flux.
特別地，有一種簡(jiǎn)單的情況，是不用計(jì)算的,當(dāng)向量場(chǎng)與曲面相切,沒(méi)有通量。
And, in some cases, for example, if you know that the vector field is tangent to the curve or if a dot product is constant or things like that then that might actually give you a very easy answer.
例如，在某些情況下，如果已知向量場(chǎng)與曲線相切,或者內(nèi)積是一個(gè)常數(shù)等等,那么結(jié)果將會(huì)很簡(jiǎn)單。
