例如许多出版商印刷图书或者是电子版上线的周期过长以至于失去了有价值的商机。

Many publishers, for example, still take far too long to get books to market in print or electronic form, missing valuable opportunities.

电子通过铜线传输，使当今电脑（以时序周期方式）工作，而用光子替代电子的吸引力（好处）是显而易见的。

It is easy to see the attraction of replacing electrons, which travel along copper wires and make today’s computers tick, with photons.

So, that's actually the electron configuration we have when we're talking about copper and some other exceptions in the periodic table that you're going to be looking at.

因此，这才是铜原子真正的电子排布,而且我们在元素周期表中,会看到与铜原子类似的,其他例外的情况。

We'll then take a turn to talking about the periodic table, we'll look at a bunch of periodic trends, including ionization energy, electron affinity, electronegativity and atomic radius.

然后我们再开始讲元素周期表，我们会看到很多周期性规律，比如电离能，电子亲和能，电负性以及原子半径。

So let's talk about another periodic trend, this one is called electron affinity.

那么下面我们来讨论一下另一个周期性规律，它被称作电子亲和能。
