是问这句话什么意思还是要翻译？翻译如下：Password rule: Must be 6~12 digits of English or numbers, and is composed of only 0~9 Roman numerals, and alphabet a~z.或者Password rule: Must be 6~12 digits composed of English alphabet from a~z or Roman numerals from 0~9.如果问这句话什么意思， 就是说密码的长度必须是6到12位，而且只能由英文字母（从a到z）或数字（从0到9）组成。希望能帮到你^^...
