摘　　要：为研究激光通信终端(LCT)有效距离及星间链路(ISL)对“星链”卫星网络属性的影响,针对“星链”系统中各卫星节点及节点间关系,依据网络科学理论、轨道学和LCT性能,设定8类LCT有效距离与3种ISL规则,构建“星链”卫星网络模型。通过对比分析各种规则不同有效距离参数下的“星链”卫星网络中度值和平均最短路径值,发现LCT有效距离是影响“星链”卫星网络中信息传递效率的关键因素。ISL对提高网络信息传递交互性能,增加信息连通路径具有重要作用。研究成果为多角度研究“星链”卫星网络提供模型参考,为评估“星链”网络因素和ISL规则影响提供一种新思路。To investigate the impact of laser communication terminal(LCT)effective distance and in-ter-satellite link(ISL)on the attributes of the“Starlink”satellite network,8 types of LCT effective dis-tances and 3 types of ISL rules are established based on network science theory,orbit theory,and LCT performance,focusing on satellite nodes and their connectivity.The“Starlink”satellite network model is then constructed.Through comparative analysis of the degree value and the average shortest path value of the“Starlink”satellite network across various LCT effective distances under different ISL rules,it is found that the effective distance of LCT is a crucial factor influencing the information trans-mission efficiency within the network.Additionally,ISL is identified as playing a significant role in en-hancing the interactive performance of network information transmission and increasing the informa-tion connectivity path.The research results provide a model reference for the multi-dimensional study of the“Starlink”satellite network and propose a novel approach to assessing the influence of network factors and the characteristics of ISL rules.
