Dianci bileiqi, 2023 加装单相同线安装方式的并联间隙，可有效提升10 kV架空裸导线路的耐雷水平。但目前相关研究仅针对10 kV单回架空线路，多回线路中仍存在并联间隙的安装数量、安装位置和放电电压数值的匹配问题。为此，本研究基于ATP-EMTP软件，搭建10 kV双回架空配电线路雷电过电压仿真模型。针对多回10 kV架空线路，分析了单相安装并联间隙的配置方法，并设计了多回线路耐雷水平的计算流程。以双回线路为计算实例，线路遭受感应雷过电压时，建议在每回线路的最高相上均安装一只并联间隙；线路遭受直击雷过电压时 ...

Digital Futures Between Participatory Digital Democracy and Participatory Digital Fascism
Policy &Internet, Volume 18, Issue 3, September 2026.ABSTRACT This paper explores one of the defining political questions of the twenty‐first century: will digital technologies strengthen democracy or accelerate new forms of authoritarianism and fascism? Against the backdrop of platform capitalism, AI‐driven communication, surveillance infrastructures, disinformation and democratic crisis, the study asks

Rare Metals, Volume 45, Issue 7, July 2026.ABSTRACT Bio‐inspired artificial vision systems have made significant progress, but most focus on photo‐receptors, neglecting the hardware implementation of the efficient downstream neural circuits for complex computations like motion detection. To overcome this bottleneck, we demonstrate a neuromorphic vision system that mimics Drosophila's motion ...

Rare Metals, Volume 45, Issue 7, July 2026.ABSTRACT Germanium is a critical dispersed metal, yet sustainable recovery from dilute solutions is limited by sorbents that are difficult to regenerate and operate in continuous mode. Here, we fabricate a regenerable 3D‐printed hydrogel monolith (3D‐ATO‐GS) by integrating hydroxyl‐rich amorphous TiO2 nanoparticles into an alginate/gelatin scaffold ...

Gaoya dianqi, 2020 GIS回路中导电接触状态关系到GIS的安全运行。文中通过对GIS回路电阻特性的研究,指出了通过直流法测量回路电阻来评估GIS回路接触状态的不足,发现直流法在测量回路电阻时存在一定随机性,且直流法通流时间短、电流幅值小、没有交流电动力的影响,与实际运行时的设备状况相差较大,不能准确反映GIS回路接触的真实情况,也不能用于对GIS回路电接触劣化程度进行准确评估。为了探究实际运行中导体发热和电动力产生的振动等因素对电接触的影响,文中在GIS设备中通过交流电流进行温升试验,并利用交流法计算了温升过程中回路电阻 ...

People and Nature, Volume 8, Issue 6, Page 1705-1727, June 2026.Abstract Active outdoor play has been positioned in the literature as an opportunity to address concerns over climate (in)action and the rising trend of disconnection from the outdoors and nature. The objective of this systematic review was to examine associations between active outdoor play and people's connection to nature and/or environmental ...

Gaoya dianqi, 2003 用合成试验回路对GarabiⅡHVDC晶闸管阀进行了运行试验。这个由传统的背靠背直接试验回路和电压振荡回路组成的合成试验回路能够产生晶闸管阀在实际运行中承受的电流和电压。该试验回路参数的选取接近系统的实际参数。从合成试验回路所获得的样品试验结果和以前从传统的背靠背试验回路获得试验结果是相同的。然而,这种合成试验回路更具有技术上的优势,并且在经济上也优于背靠背直接试验回路。
