摘　　要：以网络计量学领域的网站链接数为基础,研究网址入链分布规律。首先,通过研究中网站之间的链接关系,选定入链数作为研究对象,并获取原始数据;接着,利用最小二乘法、K-S检验算法以及M.L.Pao教授提出的指数不为2时的逼近c值的估计公式对数据进行洛特卡定律拟合,发现网络计量学领域的网址入链分布并不服从洛特卡定律。最后,讨论造成不服从洛特卡定律的原因。The distribution of websites＇ incoming links is analyzed based on the number of websites＇ incoming links in the field of webometrics. Firstly, the number of incoming links is chosen to be the research object and original data are collected by analyzing the link relationship between each website. Then, least squares and K-S test, as well as Miranda Lee Pao＇s estimation formula about c value when n is not 2, are applied to make a Lotka＇ s law fit about data. It is discovered that the distribution of websites＇ incoming links does not obey Lotka＇s law. Finally, the reasons why the distribution of websites＇ incoming links disobeys Lotka＇ s law are discussed.
