Quantifiers are words that limit quantities that are less exact ( rougher ) than numerals 数量词是限制数量的字。数量词所限制的数量比数字较为不准确(较粗略的) 。
A quantifier expression applies to the character , group , or character class that immediately precedes it 限定符表达式应用于紧挨着它前面的字符、组或字符类。
Matches the preceding character or subexpression zero or one time , or indicates a non - greedy quantifier 零次或一次匹配前面的字符或子表达式，或指示“非贪心”限定符。
We can also extend the language of temporal logic to include quantifiers over collections of values in databases 我们还可以扩展时态逻辑的语言以包括数据库中值集合的量词。
A capturing group can capture zero , one , or more strings in a single match because of quantifiers , so group 由于存在数量词，一个捕获组可以在单个匹配中捕获零个、一个或更多的字符串，因此
For example , the parser treats an asterisk as a repeating quantifier and a backslash followed by an asterisk as the unicode character 002a 例如，分析器将星号( * )视为重复限定符，而将后跟星号的反斜杠( * )视为unicode字符002a 。
Admittedly , these very general quantifiers make it more difficult to state specific cardinality constraints , as you can with the w3c xml schema 不可否认的是，这些非常常规的量词却使声明特定基数约束变得更困难，就如您用w3c xml schema
This paper discusses the development of four different kinds of the quantifier phrase " y - xi " both from the synchronic and the diachronic perspective 摘要文章采用历时与共时相结合的方法，论述了数量结构“一下”的衍生、发展以及词化机制。
Quantifiers can be used within the regular expressions of the spark tokenizer , and can be simulated by recursion in parse expression grammars 计量符可以在spark记号赋予器（ tokenizer ）的正则表达式中使用，并可以用解析表达式语法中的递归来进行模拟。
The quantifier word " y - xi " originates from the verb " y - xi " . " once " is the original meaning of the quantifier phrase " y - xi " 认为数量结构“一下”的“一次”义是动词词组“一下”的转义，由转义先后派生出“瞬间” 、 “时短” 、 “尝试”等三种意义。
