Journal of Applied Ecology, Volume 63, Issue 4, April 2026.The modified PSR framework proved valuable for assessing conservation effectiveness and identifying research gaps for waterbirds in the EAAF. Recognizing similar threats to other migratory species globally, we urge action to: (1) prioritize regionally relevant research validating frontline conservation actions, (2) enhance communication between ...

Gaoya dianqi, 2011 同塔双回架空输电线路,测量I回线路零序阻抗,II回线路双端短路接地,其三相导线、地线与大地构成零序电流的通路,II回线路亦可等效为连续接地的避雷线,避雷线相当于I回线路的一个二次短路线圈,对I回线路磁场起去磁作用,引起I回线路零序阻抗幅值的降低和相角的变化。笔者理论分析同塔双回输电线路地线连续接地对零序阻抗测量结果准确性的影响,通过EMTP对典型同塔双回输电线路零序阻抗参数进行仿真计算,并且分析了4条500 kV线路、2条220 kV线路的零序阻抗实测结果,提出了现场实际测量中应该注意到的问题 ...

Gaoya dianqi, 2019 为对比全硬管母连接和分段管母组合六分裂导线连接两种连接方式对直流场回路抗震性能的影响,以某换流站直流场±400 kV回路为研究对象,建立了不同连接条件下该回路的精细化有限元模型,获得了回路支柱绝缘子的地震响应。对不同条件下回路中支柱绝缘子的地震响应进行了对比分析,发现绝缘子的位置和回路的连接方式对绝缘子地震响应有较大影响。进一步得到如下结论:该回路在地震作用下易发生整体扭转,回路两端绝缘子地震响应较中间绝缘子大;全硬管母连接方式下回路整体性好,地震响应可以较好的均分给各个支柱绝缘子 ...

Rare Metals, Volume 45, Issue 3, March 2026.ABSTRACT As a promising alternative to sluggish Li2CO3‐based Li‐CO2 electrochemistry, Li2C2O4 offers a favorable 2e− discharge pathway, yet its selective formation and reversible decomposition remain debated. Herein, we propose a nonmetal‐metal synergistic catalyst—B‐Ti coregulated layered transition metal boride Ti18B18O9/graphene (B‐Ti/TiBOG)—to ...

China's Belt and Road and the Global South: A Normative Challenge to the Liberal International Order
World Affairs, Volume 189, Issue 2, Summer 2026.ABSTRACT The Belt and Road Initiative (BRI) has been the subject of a substantial body of scholarship, some of which has focused on its revisionist character. However, relatively few studies examine this issue in the context of the BRI's presence in the Global South.

Gaoya dianqi, 2015 文中采用Deutsch假设和现场实测相结合的方法,分析了特高压、并行双回特高压直流输电线路下地面合成场强的分布特性。结果表明:基于Deutsch假设计算的结果与实测结果吻合,适用于实际工程合成场强的预测。双回特高压直流线路并行时,由于空间正负离子流的相互影响作用,其场强分布与导线排列方式有较大关系,两回路线路内侧极性相同时,并行线路之间区域合成场强较单回增加,内侧极性相反时,并行线路之间区域场强较单回减小。同时,随着两回线路之间距离的减小,或线路高度的增加,与单回路相比 ...

Rare Metals, Volume 45, Issue 2, February 2026.ABSTRACT Rare earth elements (REEs) play an irreplaceable role in modern technology and industry. However, due to the highly similar physicochemical properties among REEs, their separation remains a significant challenge. Additionally, REEs often exist in low‐concentration solutions, making efficient REE recovery an urgent task.
