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 ...

Rare Metals, EarlyView.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 ...

International Journal of Applied Linguistics, Volume 36, Issue 1, Page 714-724, February 2026.ABSTRACT Interlingual translation, as defined by Roman Jakobson, refers to the transfer of meaning between languages. However, this concept has often been conflated with linguistic shifts between distinct cultures and nation‐states. To challenge this misconception, I propose the concept of self‐consumption translation (SCT), a subfield of interlingual ...

An Approach to the geometric state assignment method of sequential machines [PDF]
, 1971 This paper states on a method for state assignment of sequential machines design. This is very excellent means for its design from the viewpoint of the easiness. This is constructed of the combination between the hamming distance on cube and the state of

Journal of Critical Infrastructure Policy, Volume 7, Issue 1, Spring/Summer 2026.ABSTRACT Bangladesh's goal of achieving high‐income status by 2041 requires dependable, low‐emission, and affordable energy. With near‐universal grid coverage and increasing demand, nuclear energy is a strategic asset for long‐term baseload supply. However, the existing financing model, typified by the country's most expensive $12.65 billion Rooppur ...

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 ...

International Journal of Urban and Regional Research, Volume 50, Issue 1, Page 191-220, January 2026.Abstract Henry George advocated for capturing land value increases for public ends. The active approach of public authorities organizing and financing land development can help capture higher land value increases, as Hartman and Spit indicate. However, this approach hardly happens in developing countries, where the coalition of private developers and ...

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。
