摘要
以《物理学报》5年所载论文的引文为数据,采用Burton-Kebler方程及中值法计算了半衰期,并得出了物理学文献的半衰期为9.2年,与实际统计的数据相吻合.
In this paper,we depend on the data of the papers quotation pubilished on the 《ACTA PHYSICA SINICA》 during the past five years, Burton-Kebler equation has been used to calculate half-life of the physics literature.As a result,half-life is 9.2 years,it is in agreement with our collecting actual data.
