You can put somebody in an MRI machine now and have them read a book and look at what parts of their brain become activated when they're reading and what parts stop activating when they stop reading, so you can learn where in their brain is reading done.

现在如果有人躺在核磁共振仪中进行阅读,我们就可以看到,在阅读时,大脑哪些部位变得活跃,停止阅读时哪些部位停止活动,这样我们就知道了,大脑中什么部位是和阅读相关的

that's one way to think about it, and there's also another way, and this is the way that your book presents it. If you, in fact, have two of the same atom right next to each other, let's say you have a crystal, or let's say you're talking about a metal, what you can do is just look at the distance between the two nuclei, and split that in 1/2, and take the atomic radius that way.

这只是一种定义的思路，另外还有其它方法，也就是你们课本上的方法，如果你，事实上，有两个相同的原子彼此靠在一起，比如说你有一个晶体，或者说你讨论的是一个金属，你所要做的就是,看看这两个原子核之间的距离，然后将距离除以二，就得到了这个原子的半径。

焓也是一样，焓是U加,所以需要定义一个任意的设定值,对吧？因为实际上你在实验室里,测得的是焓的改变,就像你在研究某种能量变化时，所测量的那样，你测量的是能量的改变，对吧。
