The eq operator can only be used to compare atomic values.
eq操作符只能用于比较原子值。
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。
You can create a sequence that contains the atomic values shown in Listing 1, plus all of the elements, as shown in Listing 2.
您可以创建一个序列，其中包含清单1 所示的原子值，以及 清单2 所示的所有元素。
Just remember: Every eq operator is a potential error and should only be used when you can be fairly sure it is dealing with atomic values.
只需记住：每个eq操作符都可能出现错误，您只有在相当确信处理的是原子值时才能使用它。
XPath 2.0 works on sequences, and sequences can contain nodes (so you're not loosing anything) as well as strings, integers, and other atomic values.
XPath 2.0可以操作序列，而序列可以包含节点(所以不会丢失任何内容)以及字符串、整数和其他原子值。
Listing 1, taken from the upcoming sample application in which you'll manage the data for a 16-team single-elimination tournament, shows an example of a sequence of atomic values.
您将在后面的一个示例应用程序中管理一组锦标赛数据，这是一场由16支队伍参加的单场淘汰赛，取自该程序的清单1展示了一个原子值序列的示例。
Sequences are a new way to look at an old concept, broadening the notion of node-sets to include atomic (primitive non-node) values.
序列是观察旧概念的一种新方式，它拓展了节点集的概念，将原子值（非节点的基本数据）包括了进来。
This class USES DOM and provides a way to query using XPath for document manipulation and extracting atomic node values.
这个类使用了DOM并提供了使用XPath查询来获得文档操纵以及提取原子节点值的一种方式。
To locate an atomic node value is to extract desired values from the XML document.
定位原子节点值也就是从XML文档中提取想要的值。
Subqueries are generally used to return a single row as an atomic value although they may be used to compare values against multiple rows with the IN keyword.
子查询一般用来返回一个单独的行作为原子值，然而还可以用来比较多行的值，利用IN关键字。
The variable $values is neither a node-set nor an IDN; it is just a sequence of atomic double-precision numbers.
变量 $values既不是节点集也不是IDN，仅仅是一个原子性的双精度数序列。
Precision values of atomic masses are measured in a device called a mass spectroscope.
原子质量的精确值是用一种称为质谱仪的装置来测量的。
The new scale required only minimal changes to the values that had been used for chemical atomic weights.
依据这个新标度，原先的化学原子量数值只需作很小的变动。
Attribute values should be atomic, that is, present a single fact. Having disaggregated data allows simpler programming, greater reusability of data, and easier implementation of changes.
属性值应该是原子性的，即介绍一个单一的事实，分类数据允许简化编程、加强可用性，易于执行修改。
