我们的宇宙从所有方向看，大致是相同的，甚至包括比自大爆炸后光传播最远的距离更远的分离区域。

The universe looks roughly the same in all directions-even parts that seem to be separated by more than the distance light has traveled since the Big Bang.

分析原子的纠缠度对约化后光场性质的影响，结果表明纠缠度强烈影响光场的平均光子数分布和二阶量子相干性。

It is proved that the average photon Numbers and the second-order quantum coherence are dramatically influenced by the entangled degree of the atoms.

So, we'll take a little bit of a step back after we introduce quantum mechanics, and talk about light as a wave, and the characteristic of waves, and then light as a particle. And one example of this is in the photoelectric effect.

等我们介绍完量子力学后,我们要回过头来讨论下光,作为一种波和它的波动性特征,以及光作为一种粒子,其中的一个粒子就是光电效应。
