摘要
利用近似数表示数字的概念，分析和完善了近似数的有效结构与可靠结构．并得到了有效位与可靠位的关系。
Using the concept representative digit of approximate number, this paper analyses and consummates the signficant structure and reliable structure.It obtains the relation of the signficant digits and the reliable digits, and gives the error estimations on signficant truncation number and reliable truncation number.
