摘　　要：本论文利用社会关系网络中某大型社区人们之间电子邮件通信数据库,对人类动力学标度特征进行实证分析研究。在项目合作组成员验证了社区中个体发送电子邮件的时间间隔统计特性满足幂律分布的基础上,分析了社区成员接收、回复电子邮件的时间间隔统计特性均具有明显偏离指数分布的尖峰重尾,用幂函数能够很好的拟合,发现个体层面的幂律指数并非传统的具有离散指数的普适类。In this thesis, the empirical analysis of the scale feature of human dynamics has been made through a database of email between a large community of people in the social network. The project cooperation members have proved the statistical properties of time interval distribution by individual＇s email sending in the community is corresponding to the power-law distribution. On the basis of which, the paper analyzes the statistical properties of time interval distribution by individual＇s email sending, receiving and reply in the community. The study obviously shows they all have the leptokurtosis and fat-tailed which deviate from the exponential distribution. We found that the power-law index of the individual＇s level is not a traditional universality class that has discrete index.
