表示顺序的数字serial number

• 一同报名的人，准考证序号绝无相连现象，可更好地避免作弊产生。

  People who sign up together are given permits with numbers that are not consecutive, so cheating can be more easily avoided.

• 除了考生本人，所有人都不知道考生的序号。

  Apart from the examination candidates themselves, no other people know the candidates' serial numbers.
