However, the final nucleus density obtained on gradually increasing the methane concentration from 0.6% to 1.2% is smaller than that deposited at a methane concentration of 1.2%.

但是甲烷浓度由0.6%逐渐增加到1.2%时，所得最终形核密度比一开始就将甲烷浓度设为1.2%的形核密度低。

What you see is near the nucleus that the density is the strongest and that the dots are the closest together.

你看在核子附近，密度最强，这些点在一起最近。

So, what you see is near the nucleus, the density is the strongest, the dots are closest together.

你看在核子附近，密度非常高，这些点非常密。

At first it might be counter-intuitive because we know the probability density at the nucleus is the greatest.

起初我们觉得这和直观感觉很不相符,因为我们知道在原子核,出的概率密度是最高的。

Again, we have continuous electron density from one nucleus to the other.

再说一遍，原子核间有不间断的电子云,相接没有节点，没有空缺。
