英汉例句

• it measures failure of a vector field to be conservative.

  它用来衡量向量场是不是保守场的。

• we need, actually, a vector field that is well-defined everywhere.

  实际上我们需要，一个处处有定义的向量场。

• that was a vector field in the plane.

  它是一个在平面上的向量场。

• it says that the work done by a vector field along a closed curve can be replaced by a double integral of curl f.

  物体在向量场里面做功的路径是封闭曲线的话,它所做的功可以写成一个二重积分。

• actually, they have a vector field is still pointing perpendicular to the level curves that we have seen, just to remind you.

• the problem is not every vector field is a gradient.

  问题是，不是所有向量场都是梯度。

• my vector field is really sticking out everywhere away from the origin.

  即给定的向量场是以原点为心向外延伸的。

• and we used a vector field that represents the flow of whatever the substance is whose diffusion we are studying.

  我们用向量场表示物质的扩散,而其扩散就是我们要研究的内容。

• what changes is, of course, my vector field is no longer sticking straight out so i cannot use this easy geometric argument.

  有所变化的是，向量场不是由原点直接向外辐射,从而我们不能再用一些简单的几何直观去解释。

• so, the divergence theorem gives us a way to compute the flux of a vector field for a closed surface.

  有一个向量场来描述每一个点上的向量。

• in fact,our vector field and our normal vector are parallel to each other.

  事实上，给定的向量场与法向量是相互平行的。

• well, we「ve seen this criterion that if a curl of the vector field is zero and it」s defined in the entire plane, then the vector field is conservative, and it's a gradient field.

  我们已经知道了一个準则,如果向量场的旋度为零,而且它在整个平面上有定义，那么这个向量场是保守的，而且它是个梯度场。

• the curl of a vector field in space is actually a vector field, not a scalar function. i have delayed the inevitable.

  空间中的向量场的旋度，是一个向量场，而不是一个标量函数，我必须告诉你们。

• one place where it comes up is when we try to understand whether a vector field is conservative.

  当需要判断一个向量场是否保守向量场时,旋度也会派上用场的。

• that would be given by a vector field that points toward the origin and whose magnitude is inversely proportional to the square of a distance from the origin.
