1.【数】单元的,一元的
1.describes a mathematical operation that is applied to only one member of a set at a time, e.g. squaring a number
1.Returns a value generated by rolling up the values of the children of a specified member using the specified unary operator.
使用指定的一元运算符，通过汇总指定成员的子成员的值，从而返回所生成的值。
2.A UML operation representing a binary operator is named similarly to unary operator, but the symbol is one of the binary operators.
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。
3.An unusual use of the unary + operator was used in front of a function call that did not have parenthesis.
在没有括号的函数调用前使用了一元+运算符的异常用法。
4.Is a partial application that adapts the binary multiplication to be a unary closure by using a constant second operand.
是个局部应用程序，通过使用一个不变的第二操作数，把二元乘法改变成一元闭包。
5.The unary operator -z tests for a null string, while -n or no operator at all returns True if a string is not empty.
单目操作符-z测试null字符串，如果字符串非空-n返回True（或者根本没有操作符）。
6.The Java compiler first applies any unary minus operators (a minus sign with no operand to its left).
Java编译器首先应用一元负号运算符（左侧没有操作数的减号）
7.The MDX statement examines the unary operator of the child member .
MDX语句检查子成员的一元运算符。
8.If the coefficient of the first term is negative, it is preceded by a unary minus in the first column, with no intervening blank column.
如果第一项的系数为负，则需在行首打印一元运算符负号，后面没有空格。
9.Performs a unary operation that returns the positive value of a numeric expression .
执行一元运算，返回数值表达式的负值。
10.Finally, the -a and -o options allow you to combine expressions with logical AND and OR, respectively, while the unary !
最后，-a和-o选项允许使用逻辑运算符AND和OR将表达式组合在一起。
