双语使用场景

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。

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，在某些情况下，如果已知向量场与曲线相切，或者内积是一个常数等等，那么结果将会很简单。

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.───因此即使速率不变，也就是说速度矢量的的大小不变，但它的方向可以做旋转。

英语使用场景

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.
