| 摘 要： | 用中国植物生理学和美国社会学期刊的发文数据对洛特卡规律进行了验证,并设计了一个基于概率优势积累选拔机制的仿真模型,以模拟发文率差异的形成过程。模拟的结果与理论预测和经验数据有较好的吻合。

| Abstract: | Data of scientific productivity are collected fro m journals in Chinese plant physiology and American sociology to test the so-call ed Lotka's Law. A model of the selection mechanism with probability accumulative advantage is designed to simulate the cumulative process of productivity differ ences. The results fit fairly well with empirical data and the data expected by the Lotka's Law. |
