摘　　要： 近年来,Albert Barabási等通过实证研究发现:人类行为发生的间隔时间并不都符合泊松分布,有的服从幂律分布,并提出了两个普适类。本文通过对QQ群上6000多条发言消息的记录进行统计分析,发现QQ群发言时间间隔服从广延指数分布(SED),SED指数为0.2和0.15。这与Barabási的研究有一定区别,通过查阅文献初步判断是由于qq在线聊天主要是由兴趣和互动驱动的,不同于Barabási所研究的人类优先行为的动力学。 In recent years, Albert Barabasi and other researchers, through empirical research based on the real data, confirm that the interval between the occurrences of human behavior is not in line with the Poisson distribution, but follows a power law distribution. They also propose two universal categories. This paper analyzes more than 6000 speeches in the QQ group and finds the speaking time interval of the QQ group subject to SED. In addition to this, we also find the SED index under 0.2 and 0.15 by the data fitting. Our finding is to some extent different from Barabasi＇s, and we argue that this difference is mainly due to the QQ online chat driven by interest and interaction, and that Barabasi＇s study only aims at the dynamic behavior of human priorities.
