The bit vector occupies ( n _ nullable + 7 ) / 8 bytes 位向量占用了（可空的列数7 ） 8字节。
The record header contains a bit vector for indicating null columns 记录头包含一个位向量，用来指明空列。
Columns that are null will not occupy other space than the bit in this vector 值为空的列不会再占用此位向量以外的空间。
It runs at least 14 % faster than the known fasted algorithms 本文改进了位向量方法，使其在应用于中文字符串时，空间需求降低到约5 % 。
It is perfectly suited for long bit vectors such as dna or other numeric data 它非常适合于象dna或者其它的数值数据之类的长的位向量。
This would be a problem for some little computer which has a small memory , such as embedded system 由于汉字众多，应用位向量方法时，需要大量空间。
Since chinese alphabet has many characters , it needs much computer memory for bit - vector method 目前字符串模糊匹配的两个主要方法是位向量方法和过滤方法。
Contains specialized and strongly typed collections ; for example , a linked list dictionary , a bit vector , and collections that contain only strings 包含专用的强类型集合；例如，链接表词典、位向量以及只包含字符串的集合。
Specialized and strongly typed collection classes , such as linked - list and hybrid dictionaries , bit - vector and name - object collections , and string - only collections 专用的强类型集合类，如链接表和混合字典、位向量和名称对象集合以及仅包含字符串的集合
Somewhere over half of all the standard rexx functions are for working with strings , with a chunk of others thrown in for quite readable manipulation of bit vectors 可能有超过一半的标准rexx函数用于处理字符串，其他的大部分被用来以极其显而易见的方式处理位向量。
