我国农村能源系统是我国能源系统的重要组成部分,防止农村居民陷入能源贫困对促进农村居民生活用能清洁化具有重要的现实意义。利用2020年的中国家庭追踪调查数据,采用分位数回归模型测算农村地区能源贫困线,并分析了影响能源消费支出的因素,进一步利用二值选择模型判断影响清洁能源选择的因素,并比较二者。研究发现,能源消费支出对人均家庭资产有阶梯效应,但对人均收入没有表现出阶梯效应;清洁能源选择和管道设施分别通过调节人均收入和人均家庭资产而增加能源消费支出;管道设施和人均家庭资产都可以促进清洁能源的选择,且二者具有替代效应。综上提出相关政策建议,为促进农村居民生活用能清洁化和防止农村居民陷入能源贫困提供有益参考。

为了研究材料腐蚀作用下输电塔的安全性,通过数值模拟方法结合实验数据建立了输电塔镀锌钢材腐蚀后承载力退化模型。腐蚀效应通过在模型中引入人工腐蚀试验得到的材料力学参数和本构模型实现。在精细化有限元建模基础上对结构各关键点施加风荷载,以逐级加载方法计算不同腐蚀程度的模型关键点和塔腿的最大响应确定结构极限承载力。结果表明,由于腐蚀导致结构质量、刚度下降,输电塔基频随着腐蚀时间的增加不断降低,在镀锌钢材腐蚀周期为1200 h和4200 h时,输电塔承载力分别退化4.2%和5.3%。

为研究角度风下长横担输电塔线体系动力响应,采用有限元时程方法分析准东—华东±1100 kV特高压输电线路单塔及塔线体系风振响应。首先,利用线性滤波法计算得到三维脉动风速场,并结合准定常理论得到单塔及输电塔线体系脉动风荷载。其次,建立单塔及输电塔线体系有限元模型,利用模态分析方法计算结构的动力特性,研究导地线及长横担结构对输电塔动力特性的影响。最后,利用有限元时程方法对单塔及塔线体系进行动力分析,研究了风向角、长横担结构及塔线耦合效应等因素对结构动力响应的影响。结果表明:长横担结构会导致扭转频率降低,扭转振型出现顺序前移;塔线耦合效应降低了塔架结构自振频率,提高了结构阻尼比;根据位移均值计算结果,最不利风向角为15°和75°;根据扭转角均方根计算结果,最不利风向角为0°;单塔顺风向响应主要受背景分量和1阶振型的影响,塔线体系还受到导地线低阶共振分量的影响,扭转角主要受扭转1阶振型影响。

Mineral prospectivity mapping(MPM) is designed to reduce the exploration search space by combining and analyzing geological prospecting big data. Such geological big data are too large and complex for humans to effectively handle and interpret. Artificial intelligence(AI) algorithms, which are powerful tools for mining nonlinear mineralization patterns in big data obtained from mineral exploration, have demonstrated excellent performance in MPM. However, AI-driven MPM faces several challenges, including difficult interpretability, poor generalizability, and physical inconsistencies. In this study, based on previous studies, we devised a novel workflow that aims to constructing more transparent and explainable artificial intelligence(XAI) models for MPM by embedding domain knowledge throughout the AI-driven MPM, from input data to model design and model output. This newly proposed approach provides strong geological and conceptual leads that guide the entire AI-driven MPM model training process, thereby improving model interpretability and performance. Overall, the development of XAI models for MPM is capable of embedding prior and expert knowledge throughout the modeling process, presenting a valuable and promising area for future research designed to improve MPM.
