effective radius

基本解释

In the near infrared and middle infrared spectral region, the cloud reflection function depends mainly on the cloud particle effective radius.
在近红外和中红外光谱区，云的反射函数主要依赖于云滴有效半径。
In this paper, the effective radius of oil well is included in the insideboundary in the problem of flow of fluid in a reservoir, thus a new model has been built.
本文将油井有效半径引入油藏渗流问题的内边界条件之中，从而建立了均质油藏渗流问题的新模型；
Panels (b) and (d) Cloud optical thickness and effective radius derived from all cloudy pixels, where a separate color bar is used to denote clouds processed as ice and water clouds.
b组和d组的云光学厚度和从全部云的像素导出的有效半径，用一个单独的颜色条处理表示冰水混合状的云。

But what's important is not where that most probable radius is when we're talking about the z effective it feels, what's more important is how close the electron actually can get the nucleus.
但重要的不是,最可能半径,当我们谈论它感到的有效电荷量的时候，更重要的是,电子实际上。

You just need to remember what's happening to z effective, which really tells us what's happening with all the trends, and once you know z effective, you can figure out, for example, what direction the atomic radius should be going into.
你只需要记住有效核电量的规律，实际上它会告诉我们所有的规律，只要你知道了有效核电量的规律，你就可以判断，比如，原子半径会向着哪个方向发展。
