So, for example, down here I wrote that it was n 2 and that it was h 2, but when I re-wrote the molecules up here, you saw that it's an h h single bond where it's a nitrogen-nitrogen triple bond.

比如，在这下面我写的是氮分子2,而这个是氢分子，但我在上面把这些分子的形式改写了，大家可以看到,这是一个氢与氢之间的单键，含一个氮与氮之间的三键。

Not long after Galileo saw the moon up close, inventors like Johannes Kepler, Isaac Newton and n. Cassegrain made a succession of major innovations in telescope design.

伽利略看到月球景象后不久，开普勒、牛顿、卡塞格伦都为望远镜的改进设计做出了很大贡献。

So if we're keeping n the same, we look and what we saw was that size actually decreases as we increase the value of l.

如果我们保持n不变，我们看到随着l值的,增大尺寸变小。
