And I am going to call this whole geometric factor here, I am going to put it into one number, and I am going to denote that the Madelung constant.
接下来我将会称这一部分为几何因子，我将把它们整合在一个数字里，我将会标注它为马德隆常数。

Some of these questions that look very straightforward just naming the geometry, you have to remember to do the first step before you jump in and go ahead with a naming.
有些题目是十分直接的,仅仅是说出几何形状，你们要记住在说出它的形状之前,还有一步工作要做。

Jeremy says in the text that the geometric return is always lower than the arithmetic return unless all the numbers are the same.
杰里米在书里说几何平均,总是比算术平均小,当然如果所有数字都一样,两个均值相等

A seed,a strength,a virtue,a competence that other teachers did not see, because they did not ask this question; because they asked,metaphorically speaking, ?" "how many geometric shapes do you see on the screen?"
潜能，优点，品德，能力,这些是其他老师没看到的，因为他们没提出这个问题;,打个比方，他们只会问，“你在屏幕上看到多少个几何图案“

In class on Monday, we did go over the geometries, and the geometries themselves are very straightforward, once you know what the Lewis structure is, but remember, you can't just always look at a molecule and automatically know the Lewis structure.
在周一的课上，我们讲过了几何形状，一旦你们知道了Lewis结构，这些几何形状是十分直接的，但记住，你不能总是仅仅看一眼,分子就知道它的Lewis结构。

We have two lone pairs, so if we thought about what the bonds were everywhere, 5° it would be 109 . 5, but it's bent because we're only looking at the bonds, we're not counting the Lewis structures in naming our geometry, but they do affect the angles.
我们有两个孤对，所以如果我们考虑它会成怎样的键时，应该成109。,但它是折线型，因为我们只考虑成键，在几何形状里不考虑Lewis结构，但它会影响角度。
