括号中的表达式可以扩展到多个行。
Expressions enclosed in parentheses can extend over multiple lines.
现在，我们需要知道的是，在括号中的表达式组成了一个字面函数，并且传递给了receive。
For now, what you need to know is that the expressions inside the braces constitute a single function literal that is passed to receive.
Angular对所有双花括号中的表达式求值，把求值的结果转换成字符串，并把它们跟相邻的字符串字面量连接起来。
Angular evaluates all expressions in double curly braces, converts the expression results to strings, and links them with neighboring literal strings.
而且，因为在方法的主体中只有一个表达式，我们也省略了括号，把整个方法的定义放到一行中。
Also, because there is only one expression in the method body, we drop the braces and put the entire method definition on one line.
最后对于递归表达式的情况，当解析器在表达式递归中看到括号时，就应该简单地进行回送，如清单21中所示。
Finally, for the case of recursive expressions, the parser should simply echo parentheses when it sees them within the expression recursion, as illustrated in Listing 21.
尽管清单34中的表达式能够工作，但是使用慎重应用的括号则更为清晰，并且容易改编来选择第二个、第三个或者任何其他索引。
Although the expression in Listing 34 works, using carefully applied parentheses does the job more cleanly and is easily adapted to select the second, third, or any other index.
步骤3：如果表达式中不包含其它括号，求值的过程就完成。
Step 3: If the expression doesn't contain any more parentheses, the process of evaluation is finished.
使用(和)圆括号(就像数学中的用法)将修饰符应用到子表达式。
Use (and) parentheses (just as you do in mathematics) to apply a modifier to a subexpression. Here's an example: Given text file test.txt.
在后缀表达式中，不需要括号，而且操作符的优先级也不再起作用了。
In postfix notation, the need for parentheses is eliminated and the priority of the operators is no longer relevant. You can use the following algorithm to evaluate postfix expressions.
只需要把regex放在中括号里，然后放在一个字符串的前面就可以创建一个正则表达式了。
Just put the word regex in brackets ([]) before a string to create a regular expression.
内联字段是可以通过使用方括号(即[和])嵌入到任何文本字段中的ADIEU表达式。
Inline fields are ADIEU expressions that can be embedded in any text field by using square brackets (that is, [and]).
请注意，文件路径中展开的大括号（不是完整的远程路径表达式）已用双引号括上。
Note that the brace expansion of the file path, not the full remote path expression, has been enclosed in double quotes.
从编译器的角度来说，括号括起来的表达式也是一个项，在计算过程中需要被当做一个整体单元来处理。
From the compiler's point of view, the expression in parentheses becomes a term, which must be handled as a unit before computation can proceed.
组是正则表达式中的子模式，它们包含在圆括号中。
Groups are subpatterns in the regular expression that are surrounded by parenthesis.
当在另一个标记的属性中调用方法时，大括号表示法(正式名称为表达式语言或el语法)更合适。
The curly-brace notation (formally known as Expression Language or EL syntax) is better suited for times when the method call is embedded in another tag's attributes.
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.
字面量xml中的括号“{”和“}”用于定界表达式，该表达式在运行时进行计算以构造该XML。
The braces, "{" and"} ", in the literal XML delimit expressions that are evaluated at runtime to construct the XML.
在gnuC中。一个包在圆括号里的复合声明有可能是作为表达式的。
A compound statement enclosed in parentheses may appear as an expression in GNU c.
由括号表示分组：括号中包含的任何子表达式都被看作是用于以后分组或循环的原子。
Grouping is indicated by parentheses: any sub-expression contained in parentheses is treated as if it were atomic for the purpose of further grouping or repetition.
表达式中可能使用括号来指明运算顺序，这和数学当中是一样的。
Parentheses may be used in an expression to indicate the order of operations, in the same way they are used in mathematics.
步骤6：在求值的这一步，W3Eval从表达式中除去冗余括号。
Step 6: at this point of the evaluation, W3Eval removes redundant parentheses from the expression.
要在期望静态字符串的参数中使用XPath表达式，可以通过将表达式封装在括号({和})中来调用动态xpath表达式。
To use an XPath expression within parameters that expect a static string, dynamic XPath expression invocation can be done by wrapping the expression within braces ({and}).
步骤1：为避免括号的处理，W3Eval确定哪个子表达式处于嵌套最深的那对括号中。
Step 1: To avoid dealing with parentheses, W3Eval determines which subexpression lies within the deepest nested pair of parentheses.
在规则表达式中，方括号只表示“查找与方括号中任何字符的匹配字符”。
In regular expressions, square brackets just mean "match any character in the brackets."
中括号内的表达式看起来很熟悉。
大家总是有可能想试试把方括号在赋值表达式的等号左侧，试图去更改字符串中的某一个字符。比如。
It is tempting to use the operator on the left side of an assignment, with the intention of changing a character in a string. For example.
通常比加法或乘法具有更高优先级的求幂在此示例中最后计算，因为其他表达式都放在括号中。
Exponentiation, which normally has higher precedence than addition or multiplication, is evaluated last in this example because the other expressions are enclosed in parentheses.
正则表达式中的括号用于创建子表达式。
Parentheses in a regular expression are used to create a subexpression.
要求转换后的中缀表达式中不应出现不必要的括号。
Requirements of the post-conversion infix expression in brackets should not be unnecessary.
要求转换后的中缀表达式中不应出现不必要的括号。
Requirements of the post-conversion infix expression in brackets should not be unnecessary.
