一元操作符负号和二元操作符减号的区别是什么？
What is the difference between the unary minus operator and the binary subtraction operator?
闭包rMultiply 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。
The closure rMultiply is a partial application that adapts the binary multiplication to be a unary closure by using a constant second operand.
在Scala中定义这种一元“操作符”需要一点技巧，但这只是语法上的问题而已。
Defining this unary "operator" in Scala is slightly tricky, but it's purely a syntactic nit.
结果是一个单一元素，然后可以轻松地取出这个元素的display子元素，并用标准的DOM操作在页面上显示它，见图3。
The result is a single element, and you can easily pull out the display child of that element and, with standard DOM operations, display it on the page as in Figure 3.
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。
Unary operators perform an operation on a single operand, such as returning the negative or positive value of a numeric expression.
除了上面的一元测试以外，你也可以通过一对操作符来对两个文件进行比较，如表2。
In addition to the unary tests above, you can compare two files with the binary operators shown in Table 2.
在我们的四则运算表达式里面我们可以利用继承实行从一元到二元操作符的表示，但它实质上会干扰测试。
In our arithmetic expressions we could have used inheritance to get from a unary to a binary operator node, but that would substantially violate the test.
否则，一元数字操作数保留被转换或者不被转换。
Otherwise, a unary numeric operand remains as is and is not converted.
“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.
表示调用站点上的一元动态运算，它提供绑定语义和有关操作的细节。
Represents a set of binding restrictions on theDynamicMetaObject under which the dynamic binding is valid.
具有一元化调节功能，可预置焊接电流，能自动匹配规范的焊接参数，操作简单，有利于初用者的操作。
With unified adjusting function, it can preset welding wire diameter and welding current, can automatically match out the regulated welding parameter, it's easy to for beginner to operate.
(一元加号)将改变数字字符串值为数值(之前此操作无影响)。
(unary plus) to convert the value to a number if it is a numeric string (previously it was completely ignored).
(一元加号)将改变数字字符串值为数值(之前此操作无影响)。
