圆括号

Alternatively, you can put something inside the parentheses which you want to get help on.

或者，你可以在圆括号内输入你需要获得帮助的事物。

As an example we will write a small program to read and evaluate arithmetic expressions consisting of floating point numbers, parentheses and the usual operators for addition, subtraction, and so on.

例如我们要写一个计算由浮点数、圆括号及一些常用的加、减等算术符号组成的算术表达式的程序。

A sequence like this will often be written either in square brackets [1, 2, 3, 4] or in parentheses (1, 2, 3, 4).

像这样的序列常常被放在中括号里[1，2，3，4]或者在圆括号里(1，2，3，4)。

Parentheses are not necessary around the first expression of a conditional expression, since the precedence of ?

条件表达式中第一个表达式两边的圆括号并不是必须的，这是因为条件运算符？

When we embed a conditional expression in a larger expression, we usually must parenthesize the conditional subexpression.

当我们要在一个更大的表达式中嵌入条件表达式时，通常必须用圆括号把条件表达式括起来。

For example, the conditional operator is often used to print one or another value, depending on the result of a condition. Incompletely parenthesized uses of the conditional operator in an output expression can have surprising results

例如，经常使用条件操作符根据一定的条件输出一个或另一个值，在输出表达式中，如果不严格使用圆括号将条件操作符括起来，将会得到意外的结果

1 Value stated without parenthese are the requirement .

4.1.1 没有圆括号的值是要求值。

It is handy to use the parentheses and the pipe symbol together.

这是方便使用圆括号和管道符号在一起。

The parentheses in the regular expression indicate which part of the string is the name of the included file.

在正则表达式中的圆括号表示其中的字符串是被包含文件的名字。

Parenthesized expressions are evaluated by treating each parenthesized subexpression as a unit and otherwise applying the normal precedence rules.

使用圆括号的表达式将用圆括号括起来的子表达式视为独立单元先计算，其他部分则以普通的优先级规则处理。

The reasons of iron ions content overproof in grade Ⅱ desalting water system,such as variation water quality,contamination of regenerant , operation adjustment of pretreatment system and switching operation of bed were discussed.

对二级脱盐水系统中铁离子含量超标的原因，如来水水质发生波动、再生剂受到污染、预处理系统操作调整、床体运行切换等进行了论述。
