[目的/意义]深化完善信息偶遇理论研究，以为用户提升信息偶遇能力及相关服务商优化服务内容、改进服务模式提供理论基础与思路。[方法/过程]通过半结构化访谈采集30个移动互联网信息偶遇关键事件，基于扎根分析理论，利用Nvivo11对数据进行编码分析，经过对自由节点间关系的概念化与范畴化，最终形成信息偶遇过程相关的13个树节点及7个核心树节点。[结果/结论]移动互联网信息偶遇过程可分为信息偶遇前、信息偶遇中、信息偶遇后3个阶段，包括"注意""启动""追踪""摘取""利用""返回""结束"7个环节，3个阶段分别经历了认知断带、填平断带、跨越断带从而完成偶遇信息的意义建构。
[Purpose/significance] This paper aims to further improve the theoretical research. The research results will provide the theoretical foundation and idea about developing users'information encountering ability as well as optimize service content and improving service pattern for relative service providers.[Method/process] Firstly, 30 key information encountering events of mobile Internet were collected by using semi-structural interview. Furthermore, Nvivo11 was introduced to conduct coding analysis based on Grounded Theory. After conceptualization and categorization for the relationships among free nodes, 13 tree nodes and 7 core tree nodes about information encountering process were determined.[Result/conclusion] The whole information encountering process of mobile Internet can be divided into three stages:before, in and after information encountering, which contains 7 steps, i.e., attention, start, trace, obtain, utilize, return and end. These three stages go through cognitive division, cover division and span division respectively, and then complete the sense-making of encountered information.
