现在我们就知道了通量的含义。
很快也会看到关于通量的定理。
那就无法把通量想成线积分了。
但和经常见到的通量的意义相同。
连接电荷和磁通量的元件在哪里?
Where was the device that connected charge and magnetic flux?
下面给出三维空间中通量的定义。
把电流传给电感器,就会产生磁通量。
Pass a current through an inductor, and you create a magnetic flux.
下一个知识点是,平面和空间中的通量。
这实际上是一种通量不能被定义的情形。
So, that's actually a situation where flux cannot be defined.
另一个是要取通量的曲面。
The other one is the surface for which you will be taking flux.
就让我们从通量开始吧。
再考虑这个通量积分。
游客占了增长的交通量的一部分。
其中一个就是已经说过的,通过侧面的通量为。
One is that we've said the flux through them is zero anyway.
帕雷尔大道上有很大的交通量。
热通量通过温度的变化而测量。
The heat flux is measured while the temperature is changing.
因此研究交通量预测具有重要意义。
So it has very important sense to study the traffic volume prediction.
下面应该如何,在这样的曲面上建立通量的积分。
Now, how would we actually set up a flux integral on such a surface.
高液通量塔板在工业上有很大需求。
Trays with high liquid capacity are mostly needed in process industry .
选择代表性海域开展物质通量的研究。
Choice of representative sea areas to carry out material flux research.
表层土壤年总热通量为-0。
一旦我们做出了选择,同时也就可以定义通量积分。
Now, once we have made a choice then we can define the flux integral.
通量是什么?,通量其实是又一种线积分。
What is flux? Well, flux is actually another kind of line integral.
在稳定流动中,质量通量是恒定不变的。
在稳定流动中,质量通量是恒定不变的。
平均土壤热通量为- 1。
