为了比较两个图像，则采取每个直方图桶之间的差的绝对值，并再总结这些值。

To compare two images, you take the absolute value of the difference between each histogram bucket, and then sum these values.

对，绝对值，假发，比较，当然我们还没学，我们学过其他的一些东西了。

And you probably recognize some of them in there, cors right, absolute value, add, comp, cors, cors well we didn't do cors, we did a bunch of other things.

这些东西并不是试图给出获得认证价值的绝对值，而是你可以拿它作出比较，可以帮助你选择你的学习路径。

These mechanisms don't attempt to give some sort of absolute value of a certification, but rather one objective comparison that might help you choose.

But we could, for example, look at a case where we have several different structures that look pretty good, and the one we want to determine as being the lowest energy structure is the one in which the absolute values of the formal charges are going to be lower, so essentially that they have less charge separation.

但是我们可能，比如，遇到一种情况,有好几个候选的路易斯结构看起来都挺好的，这时候我们就需要,通过比较哪个形式电荷的绝对值更低,来决定哪个结构的能量更低，本质上这个结构中分开的电荷更少。
