雙語使用場景

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.───如果取的向量場是處處恒定的，所有點都是平移關系，所以沒有散度，因為導數為零。

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，如果已知向量場與曲線相切，或者內積是一個常數等等，那么結果將會很簡單。

So, even if the speed is constant, that means, even if a length of the velocity vector stays the same, the velocity vector can still rotate.───因此即使速率不變，也就是說速度矢量的的大小不變，但它的方向可以做旋轉。

英語使用場景

The principle of the calibration is the following : An accelerometer, on a vehicle at rest measures a constant vector ( the opposite of gravity ) in the earth frame, expressed in the vehicle frame.

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.

If I take a constant vector field, so everything translates at the same speed, 0 then obviously when you take the partial derivatives 0 you will just get a bunch of zeros so the curl will be zero.
