What should we call these iPhone-like, touch screen Wi-Fi phones with music and video, real Web browsers, E-mail, sensors (light, tilt, location, proximity), and, above all, app stores?

对于这些与iPhone类似的有音乐和视频功能、有真正的网络浏览器、有电子邮件功能、传感器(光、斜度、位置、邻近情形)，另外，还有应用程序商店的触摸屏wi - fi手机，我们到底应该叫它们什么呢？

Unlike conventional display screens, which are lit from behind, e-readers use reflected light in a way similar to paper.

不像传统的从内部照明的显示器，电子阅读器使用的是从某方面说像照在纸上的反射光。

So, now we can talk about it in different terms, Ei for example, talking about e sub i, which is the incident energy or the energy of the light that comes in, or talking about work function here, and that's just another way to say threshold energy.

现在我们可以从不同的方面,来谈论它了，举例来说，它是入射能量或者进来的光的能量,或者谈论这里的功函数，它是另一种描述临界能量的方式。

And you have to ask yourself is the energy difference here, the delta E in the electronic states, how does that compare with the E of visible light?

所以我们会问,是由于能量的不同么，例如deltaE在电子能态的不同，那如何把E与可见光联系起来？
