“进来吧，”我说，拉着凯蒂的胳臂，一半强拉她进来；

Come in, ' said I, taking Cathy by the arm and half-forcing her to re-enter;

强拉·尼娜事件对全球，特别是对热带地区产生了较大的影响。

It impacted the world climate, especially in the tropical regions.

2008年则是10年来南半球最冷的一年，这是由于强拉尼娜现象造成的。 拉尼娜现象使得热带太平洋温度低于平均值。

The report explained that 2008 was the coolest year of the decade in the southern hemisphere due to a strong La Nina phenomenon, which cooled the tropical Pacific Ocean below average temperatures.

We are expecting to see that it decreases because it's feeling a stronger pull, all the electrons are being pulled in closer to the nucleus, so that atomic size is going to get smaller.

我们将看到它是减小的,因为电子会感受到越来越强的吸引力，所有的电子将会被原子核拉得越来越近，所以原子半径将越来越小。

So because we're feeling a stronger attractive force from the nucleus, we're actually pulling that electron in closer, which means that the probability squared of where the electron is going to be is actually a smaller radius.

因为我们能感到来自原子核,的更强的吸引力，我们实际上会将电子拉的更近，那意味着电子运动的,概率半径是,事实上是一个更小的半径。

So when we talk about the size of multi-electron orbitals, they're actually going to be smaller because they're being pulled in closer to the nucleus because of that stronger attraction because of the higher charge of the nucleus in a multi-electron atom compared to a hydrogen atom.

所以当我们讨论,多电子轨道的尺寸，它们实际上会变得更小,因为多电子原子的原子核,相比于氢原子,有更高的电荷量所以,有更强的吸引力,所以可以拉的更近。
