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 ...

Dianci bileiqi, 2017 分析了大型回路中散射电压的传播对回路雷电感应过电压的影响。采用两种结构的传输线模型搭建回路:地面布置有两条传输线以及地面仅布置一条传输线。研究结果表明:由标量势引入的感应电场分量也能在回路中产生散射电压,并且散射电压的传播会在感应电压波形中引起很大的振荡,振荡波幅值和波长随着回路长度的增加而增加。当传输线回路布置在地面上方（架空线）时,电场在有耗地面中的发展和变化对回路感应电压没有影响,当传输线回路紧贴地表布置时,有耗地面中电场的发展变化将对回路感应电压产生很大影响。

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 ...

Passing on the red genes: Communism nostalgia in online fictions and ideological governance in China
Regulation &Governance, Volume 20, Issue 1, Page 119-133, January 2026.Abstract How does communism as an ideology fare in the post‐reform digital age China? What are the implications for China's ideological governance? Through online ethnographic work and text analysis, this paper identifies and analyzes how communism as an ideation and a practice is (re)memorized, (re)presented, and (re)interpreted in popular online ...

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 ...

Gaoya dianqi, 2022 换流变压器是换流变电站中的重要设备，但在历次地震中破坏严重。因此为研究±600 kV换流变压器回路的抗震性能，找寻回路中的薄弱环节，文中根据某工程建立了换流变压器回路的精细化有限元模型，并对回路进行了动力特性和地震响应分析。发现了地震作用下该回路的薄弱位置，得到了部件的连接方式和结构形式是影响结构响应的关键因素。通过将换流变压器单体和回路进行对比分析发现耦联体系可以明显减小设备在地震作用下的结构响应，同时金具内的铝绞线可以消耗由于地震作用产生的能量，起到耗能减震的作用 ...
