中文摘要：

在基于统计方法的基础上,发现了微博信息传播速率所具有的普遍规律及信息传播路径所具有的典型传播模式。首先,通过微博开放平台,采用应用程序接口对微博信息的转播/评论数据进行采集,分析信息传播速率随时间变化的统计特性,得出不同话题类型的微博信息传播特征具有非常相似的结论：信息发布后,其转播/评论数在短时间内达到峰值,然后便很快衰落;然后,通过可视化软件NodeXL对采集到的数据发现了微博信息传播的3种典型传播模式：一触即发传播模式、多级传播模式和多点触发传播模式。

英文摘要：

Based on statistical methods, universal law and information propagation path with the typical pattern on microblogging information dissemination are found. First, through the open platform, the data of microblogging＇s broadcasts and comments are collected using the application programming interface. The statistical features of information propagation changing with time are analyzed, and we draw a conclusion that the characteristics of different types of topic in microblogging information propagation are very similar. That is, after the distributed information, the number of broadcasts/comments comes up to a peak in a short time, and then quickly fades out. Then, three typical modes of transmission on microblogging information propagation, which is explosive propagation mode, multi-level transmission mode, multiple point trigger propagation mode, are discovered by applying the visualization software——NodeXL.
