2、二個(gè)數(shù)字；而交叉25碼是使用前五條黑色條碼表示第一個(gè)數(shù)字，而用介于前五個(gè)黑色條碼中的白色條碼表示第二個(gè)數(shù)字。這也是交叉25碼名稱的來源。交叉25碼是連續(xù)型、非定長、具有自動校驗(yàn)功能的雙向條碼，交叉25碼的編碼是以兩個(gè)字符為一組（上下各一個(gè)）進(jìn)行編碼，其中一個(gè)字符以條編碼，另一個(gè)字符以空編碼，每個(gè)字符由5個(gè)單元組成（3個(gè)窄單元，2個(gè)寬單元），兩個(gè)字符的條空相互交叉組合在一起。交叉25碼的起始符為：窄條-窄空-窄條-窄空，0000交叉25碼的終止符為：寬條-窄空-窄條，100交插25碼的字符集包括數(shù)字0到9如下圖示：起始符：0000，非條碼字符 ，終止符：100，非條碼字符。奇數(shù)：條；偶數(shù)位：空字

3、符集；數(shù)字09寬度調(diào)節(jié)編碼法：編碼方法以窄單元(條或空)表示邏輯值“0”，寬單元(條或空)表示邏輯值“1”。寬單元通常是窄單元的23倍。09與條或空的關(guān)系分析例子如下：0偶數(shù)位用空表示：窄窄寬寬窄 001101奇數(shù)位用條表示：寬窄窄窄寬 100012偶數(shù)位用空表示：窄寬窄窄寬 010013奇數(shù)位用條表示：寬寬窄窄窄 110004偶數(shù)位用空表示：窄窄寬窄寬 001015奇數(shù)位用條表示：寬窄寬窄窄 101006奇數(shù)位用空表示：窄寬寬窄窄 011007奇數(shù)位用條表示：窄窄窄寬寬 000118偶數(shù)位用空表示：寬窄窄寬窄 100109奇數(shù)位用條表示：窄寬窄寬窄 01010總結(jié)：起始0000 110001
