It can also create sequences of atomic values, which might be confused with node-sets.

它也可以创建原子值序列，这有可能与结点集混淆。

Value comparisons are about relationships between atomic values, and they do not check an entire set.

值比较用于原子值之间的关系，不检查整个集合。

So, these are two different definitions of how to think about atomic radius, but really what you find when these are measured is they come up with almost the identical values, so there are tables, you can look up of atomic radii and see these values, and you can trust them that, they work for both this definition and for this definition here, in most cases.

这就是,关于原子半径的两种不同的定义，但实际上你会发现按照这两种方法,测量出的值是相等的，因此有很多关于原子半径的表格，你可以通过查阅它找到这些值，你可以相信这些值，它们对于这两种定义都是适用的，在大多数情况下。
