| 摘 要： | 介绍了文献B-K老化方程产生的背景，推导了用一元线性回归求解B-K老化方程的方法．基于上述回归结果，对1994年《电子学报》引文统计数据进行分析，给出了线性方程的相关系数，检验了方程回归的显著性，求出了实例文献的半衰期为7．3年．结果表明，用B-K老化方程求文献的半衰期是简单可靠的．

| Abstract: | The background of the B-K (Burton-Kebler) equation of literature obsolescence is introduced. The equation method is particularly derived with the linear regression. Based on the above linear regression result, the method has been applied to the statistical citation datum on Acta Electronica Sinica in 1994. The correlation coefficient is found and the significance of the equation indicated in the paper. The literature half-life of above example is also solved. The literature half-life is 7.3 years. The results show that the solution literature half-life using the B-K equation is simple and reliable. |
