要进行组合，只需存储已扫描的运算符的值，就象对整数所进行的操作一样。
To mulitiplex, simply store away the scanned operator's value, exactly as you did for integers.
单目操作符(unaryoperator)是通过在关键字operator后跟单目运算符符号来命名的。
A unary operator is named by using the key word operator followed by the unary operator symbol.
表示双目运算符(binaryoperator)的UML操作的命名方式类似于单目运算符，但符号是双目运算符之一。
A UML operation representing a binary operator is named similarly to unary operator, but the symbol is one of the binary operators.
验证器插件的角色是从提交的文档中提取关键字，将这些关键字放入属性关键字中，然后让运算符匹配并让XPath执行其余的操作。
The role of the validator plug-in is to extract keywords from the submitted document, put them into the attribute keywords, and let the operator matches and XPath do the rest.
如果松绑定(looser - binding)运算符使用紧绑定(tighter - binding)运算符作为操作数表达式，那么优先级是自动处理的。
If looser-binding operators take as operands expressions using tighter-binding operators, precedence is handled automatically.
请选择一个此规则的运算符。根据您在上一节中所选的操作数，可用运算符的列表将发生更改。
Select an operator for this rule. The list of available operators will change depending on the operand you selected in the previous section.

对于类型转换运算符，操作数或返回类型必须是类或结构的数据类型。
For a type conversion operator, either the operand or the return type must be of the data type of the class or structure.
所有的赋值运算符都返回赋给左操作数的值。
All assignment operators return the value that is assigned to the left operand.
一元运算符对单个操作数执行操作，如返回数值表达式的负值或正值。

运算符处理的值称为操作数。
程序量是一种以代码中运算符和操作数为基础的度量方法，表示理解某个类型或方法的难易程度。
Program volume is a measure of the difficulty of understanding of a type or method that is based on the number of operators and operands in the code.
“一元运算符”是一种对单个操作数进行运算的运算符。
A unary operator is an operator that operates on a single operand.
幂运算符比在操作数左边的一元运算符有更高的优先级；但比右面的一元运算符要低。句法为。
The power operator binds more tightly than unary operators on its left; it binds less tightly than unary operators on its right. The syntax is.
