洛特卡定律是描述科技生产率的一个经验定律。它是从某一时期，某一主题（学科）领域众多科技工作者的科技生产率的观察数据中、模拟出来的一个著者频率与论文数量之间的关系式。这个关系式能否成立，可用X2检验和卜一名检验来检验之。但已在人证明了在验证洛特卡定律时，使用K
Lotka’s law is an empirical law that describes the productivity of science and technology. It is a relation between the author’s frequency and the number of papers simulated from the observed data on the productivity of science and technology of many scientists and technologists in a certain subject (subject) area. Whether this relation holds or not can be tested by X2 test and Bu test. However, it has been demonstrated that K is used in validating Lotka’s law
