| Abstract: | This paper proposes an algorithm of the standard document half-life period based on the characteristics of standards obviously different from other scientific and technical documents.Using the data from 5 fields including food,electronics,electrical engineering,metallurgy and agriculture,the paper gives the half-life period of 5 fields above and proves the difference among different fields of their half-life period with an empirical analysis. |
