中文摘要：

在网络空间信息扩散系统构成和动阻力分析的基础上，将信息扩散过程置于以时间、信息量和信息扩散表现为坐标轴的三维空间中，将其看作是曲折上升的阶梯式攀登过程，构建网络环境下信息扩散的阶梯网状模式。并在此基础上，对该模式的特点进行阐述与分析，揭示网络环境下信息扩散的微观运动形式。

英文摘要：

Based on the components of the information diffusion system in network space and the analysis of the powers and resist- ances, this paper puts the information diffusion process into the three-dimensional space which takes time, information content and the performance of information diffusion as the coordinate axis, regards that it is the winding rise muhistep climb process, and constructs the ladder and netlike model of information diffusion in network environment. Thereafter, the paper carries on the annotation and analy- sis to this model＇ s characteristic, and reveals the microscopic movement form of the information diffusion in network environment.
