vector field

单词vector field

基本解释

un.: 矢量场；向量场；向量字段
网络: 矢场；数矢量场；向量场理论

英汉解释

• 向量字段

• 向量场

• 矢量场

例句

• One is to say that the vector field is a gradient in a certain region of a plane.

  一个是向量场，在给定平面区域内是梯度场。

• This is just a particular kind of function that you get out of a vector field, but it is like any function.

  这只是一个由向量场得到的，有点特别的函数，但这跟别的函数是一样的。

• It measures how much a vector field goes across the curve.

  它度量有多少向量场穿过了曲线。

• Here is the statement. The curl is just going to measure how much your vector field fails to be conservative.

  下面是定理的表述，旋度是用来，度量向量场保守性的。

• 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。

• Well, I want to figure out how much my vector field is going across that surface.

  下面我们要搞清楚，这个向量场是如何穿过曲面的。

• That would be an example of a vector field that comes up in physics.

  这是物理学中向量场的例子。

• That means you need your vector field to be continuous and differentiable everywhere on the surface S.

  也就是，向量场是连续的，且在曲面S上处处可微。

• And so now, remember, curl of a vector field in space is going to be another vector expression. It has three components.

  记住，空间中向量场的旋度，是另一个向量，它有三个分量。

• Let"s not worry too much about it. For accuracy we need our vector field to be defined in a simply connected region.

  对于它，不用太担心，为了精确起见，需要向量场定义在一个单连通区域中。
