摘要
针对标准文献不同于图书、期刊等其他科技文献的特点,提出了标准文献半衰期的算法公式,并通过中国标准服务网(CSSN)收录的食品、电子、电气、冶金和农业5个领域的现行国家标准文献进行了实证分析。实证结果表明,不同领域的标准文献半衰期差异明显。
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.
