【摘要】 如何对天基网络的动态拓扑结构进行可视化展示，是当前天基网络研究中的热点问题。以时空图概念建立基于空间变化的连接关系模型，并利用空间变化事件作为时空图转换的关键节点，建立起针对天基网络的动态演化过程的时空变化模型。通过分析天基网络的稳定状态和过渡状态，提出分阶段动画转换策略和动画布局稳定性策略。并对天基信息网拓扑模型进行布局分析，精确地描述拓扑的动态性，验证了可视化布局方法适用于实现天基网络拓扑结构的动态、稳定的展示。更多还原

【Abstract】 How to visually display the dynamic topology of space-based networks has been a hot issue in the research of space-based networks. Based on the concept of space-time graphs, we established a connection model based on spatial changes in the paper is established. Using spatial change events as the key nodes of space-time graph transformation, we established a space-time variation model for the dynamic evolution of space-based networks. By analyzing the stable state and transition state of the space-based network, a staged animation conversion strategy and animation layout stability strategy wereare proposed. The layout analysis of the space-based information network topology model accurately describes the dynamics of the topology. And it verifies that the visual layout method is suitable for realizing the dynamic and stable display of the space-based network topology.更多还原
