You've probably been surrounded for years now by bytes and kilobytes, and megabytes and terabytes, and the like.

也许你已经习惯使用,字节，千字节，兆字节，兆兆字节。

I'm averaging it over the entire set of valence electrons which gives me 1.91 MJ per mole.

我是在整个价电子的集合上作平均,最后得到1。91兆焦每摩尔。

But as you probably know, a JPEG, a photograph, these are usually multiple megabytes these days which means there's a ridiculous amount of data still on that digital camera.

但是你知道，一个JPEG图片，通常是由几兆字节组成的,也就是说这些数据的大部分,仍然存在于数码相机中。

And, one other thing that I failed to point out, if you take a look at the energies associated with the outermost electrons, in this case, lithium, you see it's 0.5 megajoules per mole, and then what's the 6.26?

还有另外一点我忘记提到的是，如果你观察离最外层,的电子的能量，在这种情况，对于锂，你可以得到，它是每摩尔0。5兆焦，那么6。26是什么呢？

If you go down to 1s, it's 20 MJ per mole.

如果再往下看1s层，是一摩尔20兆焦耳。
