摘　　要：对帕菲克国际健身俱乐部全体会员近27个月的登陆信息进行了实证分析,统计结果表明:无论是全体会员、分组会员还是个体会员,其登陆系统的间隔时间均近似于幂律分布;通过按照活跃程度对俱乐部会员进行分组,发现各分组群体的间隔时间分布尽管仍呈现幂律特性,但其幂指数却各不相同,且与活跃程度之间存在一定的联系;针对某个时间段的统计结果表明,全体会员的统计特征不受时间长度的影响;此外,个体会员的登陆间隔时间分布也对应着不同的幂指数参数.研究表明在人类的健身运动模式中,间隔时间分布的标度指数可能是动态的,并与活跃度存在一定的联系.An empirical analysis of the login information of fitness club membership in foreground system is implemented, which show that the interval time distribution of their logins present obvious Power-law properties whether all members, groups or individuals. Moreover, the scaling indexes of groups are different and linked with their level of activity. Studies on a certain time and a specified object also reveal that the statistical characteristics of the same community can＇t be affected by the length of time. In addition, the power exponents of individuals are also diverse. Finally, a conclusion is given to show that the scaling indexes of interval time distribution may be dynamic and influenced by the level of activity.
