2、二个数字；而交叉25码是使用前五条黑色条码表示第一个数字，而用介于前五个黑色条码中的白色条码表示第二个数字。这也是交叉25码名称的来源。交叉25码是连续型、非定长、具有自动校验功能的双向条码，交叉25码的编码是以两个字符为一组（上下各一个）进行编码，其中一个字符以条编码，另一个字符以空编码，每个字符由5个单元组成（3个窄单元，2个宽单元），两个字符的条空相互交叉组合在一起。交叉25码的起始符为：窄条-窄空-窄条-窄空，0000交叉25码的终止符为：宽条-窄空-窄条，100交插25码的字符集包括数字0到9如下图示：起始符：0000，非条码字符 ，终止符：100，非条码字符。奇数：条；偶数位：空字

3、符集；数字09宽度调节编码法：编码方法以窄单元(条或空)表示逻辑值“0”，宽单元(条或空)表示逻辑值“1”。宽单元通常是窄单元的23倍。09与条或空的关系分析例子如下：0偶数位用空表示：窄窄宽宽窄 001101奇数位用条表示：宽窄窄窄宽 100012偶数位用空表示：窄宽窄窄宽 010013奇数位用条表示：宽宽窄窄窄 110004偶数位用空表示：窄窄宽窄宽 001015奇数位用条表示：宽窄宽窄窄 101006奇数位用空表示：窄宽宽窄窄 011007奇数位用条表示：窄窄窄宽宽 000118偶数位用空表示：宽窄窄宽窄 100109奇数位用条表示：窄宽窄宽窄 01010总结：起始0000 110001
