在当前堆栈框架的上下文中会计算表达式的值，在Display窗口的Expressions视图中会显示结果。

求值过程类似于手工计算：如果表达式中包含括号，先求嵌套最深的括号对中的子表达式的值。
The process of evaluation is similar to calculating by hand: while the expression contains parentheses, the subexpression inside the deepest nested pair of parentheses is evaluated.
像前一个示例一样，它用XPath表达式选择一组节点，然后用XQuery函数选择惟一值，并计算节点的数量。
Like the previous example, it USES an XPath expression to select a set of nodes, and applies XQuery functions for selecting distinct values and counting the number of nodes.
该输入值可以是一个简单表达式，或者是由另一节点计算的一个值。
The input value can be a simple expression or be a value computed by another node.
正如字面意义上说的，从这个函数返回，然后取得下一个表达式的值，并把这个值作为整个计算的结果返回。
Literally, return the control from this function, and take the value of the next expression, and return that as the value of the whole computation.
由查询表达式计算出来的XML“值”，可为零项、一项或者多项，而其中每一项可以是一个元素、一个属性或一个原始值。
An XML "value," computed by a query expression, may consist of zero, one, or many items, each of which may be an element, an attribute, or a primitive value.
FLWOR表达式非常像SQL中的SELECT -FROM - WHERE表达式——它用于对由多项组成的一个列表进行迭代，并且可以选择返回通过在每一项上进行计算得到的值。
A FLWOR expression is much like a SELECT-FROM-WHERE expression in SQL: it is used to iterate through a list of items and to optionally return something that is computed from each item.
如前所述，每个查询表达式都是泛型的，以表示表达式计算的值的类型。
As I mentioned earlier, every query expression is generically typed to denote the type of the value the expression evaluates to.
类型参数就是表达式要计算的值的类型。
The type argument is the type of the value the expression evaluates to.
然后，计算表达式，得到的值将替换目标节点中的现有值。
The expression is then computed and the resulting value replaces the existing value in the target node.
然后计算表达式，得到的值将替换目标节点中的现有值。
The expression is then computed, and the resulting value replaces the existing value in the target node.
表达式的结果被计算并指定为属性的值。
The expression's result is evaluated and assigned as the property's value.
这些元素包含col - spec元素，后者的select属性规定了，对应于xml源文档中当前的行元素，将使用何种表达式来计算每个行值。
These elements contain col-spec elements whose select attribute specifies, relative to the current row element from the XML source, what expressions are used for each row value.
闭包是函数字面量(unction literal)——是包含了一个递延计算的表达式，该计算可被当成值对待，在晚些时候再调用。
Closures are function literals - expressions that embody a deferred computation that can be treated as a value and invoked later.
属性值是一个XPath表达式，表达式的计算结果必须是布尔值。
The attribute value is an XPath expression that results in a Boolean after evaluation.
对选项，参数和变量来说，最有趣的变化是移除了值属性；现在值是一个Xpath表达式的计算结果，该表达式由一个选择属性定义。
The most interesting change with options, parameters, and variables is the removal of the value attribute; values are now the result of evaluating an XPath expression defined by a select attribute.
计算XPath表达式时，条件的值将会基于表达式的返回值确定。
When the XPath expression is evaluated, the value of the condition will be determined based on the return value of the expression.
如果类型属性的值不是这三个值，前三个类型替换的XPath表达式将计算为false。
If the type attribute has none of these values, the XPath expressions for the first three type alternatives will evaluate to false.
这些类型替换将依次执行计算，直到其中一个XPath表达式的值为true(如果值均不为true，则选择默认的类型定义)。
The type alternatives are evaluated in order until one of the XPath expressions evaluates to true (or, if none evaluate to true, the default type definition is chosen).
在计算XPath表达式时，条件的值将根据表达式的返回值确定，如表5所示。
When the XPath expression is evaluated, the value of the condition will be determined based on the return value of the expression as shown in Table 5.
如果height的值小于width 的值，那么断言表达式的计算结果为true，否则为false。
The assertion expression evaluates to true if the value of height is less than the value of width, otherwise it evaluates to false.
值可以在编译时计算出来的整型表达式。
An integral expression whose value can be evaluated at compile-time.

串的转换先计算所包括的表达式表的值，然后按照其结果类型所特定的规则转换其结果对象为字符串。
A string conversion evaluates the contained expression list and converts the resulting object into a string according to rules specific to its type.
