But a reliability study should be made for the valley which liable to frequent earthquakes. The color infrared aerophotos, multi-spectral photography and thermal infrared scanning had been specially done besides MSS image, processing. Researches on remote sensing applications to engineering geology, hydrogeology, deformation of neo-tectonics, Iandslide, mud-rock flow, ecological environment and geographical information system had been carried out by more than 20 research units.展开更多

Several static and dynamic network analysis methods were applied to the data for 20 years to explore the fine structure of the researcher’s network for grants. Our analysis shows that the long-term trend of researchers’ group sizes has become smaller, particularly rapidly decreasing in recent years. Some findings on researcher behavior in joining a project have also been reported.展开更多
为探究韧性电网信息物理融合系统风险研究现状及发展趋势,基于中国知网(CNKI)和Web of Science(WoS)数据库2011—2023年的文献数据,利用CiteSpace对该领域研究的研究热点、前沿及演化趋势进行可视化分析。研究结果表明:国内研究形成以...为探究韧性电网信息物理融合系统风险研究现状及发展趋势,基于中国知网(CNKI)和Web of Science(WoS)数据库2011—2023年的文献数据,利用CiteSpace对该领域研究的研究热点、前沿及演化趋势进行可视化分析。研究结果表明:国内研究形成以“风险预警与控制”和“电力系统智能化建设”为主题的研究热点,国外研究形成以“信息物理融合”和“连锁故障演化”为主题的研究热点;“智能电网的信息物理耦合”和“信息网络攻击风险分析”是国内研究的前沿方向,“信息物理融合系统安全状态估计”和“风险防控模型”是国外研究的前沿方向;国内研究可分为安全性理论研究期、信息物理攻击风险研究期和故障防御恢复研究期3个时间阶段,国外研究可分为信息物理融合研究期和信息物理安全应用期2个时间阶段;后续研究应加强改进电力信息物理融合系统建模、完善电力信息物理融合系统规划、推进电力信息物理融合系统应用,推进数字化韧性电网稳定运行。研究结果可为韧性电网风险识别和风险预警研究提供一定参考。展开更多
