摘　　要：[目的/意义]信息偶遇是信息获取行为的一种特殊途径,研究信息偶遇发生的影响机制,能够为科研人员信息偶遇发生的内外环境设计提供理论参考,丰富信息行为相关研究。[方法/过程]首先剖析过程视域下信息偶遇影响因素模型,再借助系统动力学模型分析信息偶遇影响因素间因果关系,构建相应的流图模型,最后通过仿真分析以量化形式探究各影响因素对信息偶遇发生的作用关系。[结果/结论]过程视域下科研人员信息偶遇系统主要由用户、信息和情境3个子系统所组成。其中,个性特征、信息质量水平和行为情境能够显著促进信息偶遇的发生,任务情境显著抑制信息偶遇的发生。[Purpose/significance]As a special way of information acquisition behavior,researching the mechanism of information encountering can provide theoretical reference for the internal and external environment design that effectively promotes information encountering among research users,and rich information behavior research.[Method/process]This paper firstly analyzes the influencing factors model of information encountering under the process perspective,and then comprehends the causal relationship among factors affecting information encountering by means of system dynamics model.Also,this paper constructs the corresponding flow graph model,and explores the role of various influencing factors in the occurrence of information encountering through simulation analysis and quantitative form finally.[Result/conclusion]The scientific researchers’information encountering system under the process perspective mainly consists of three subsystems:user,information and context.Among them,personality characteristics,information quality levels and behavioral contexts can significantly promote information encountering,while mission context significantly inhibits the occurrence of information encountering.
