基于Deutsch假设法同塔高压/特高压直流输电线路地面合成场强研究 [PDF]
全球能源互联网, 2018 采用Deutsch假设法，研究了不同组合架设方式下同塔双回高压/特高压直流输电线路地面合成场强的分布特性。结果表明：Deutsch假设计算结果与实测结果较吻合，适用于双回直流线路的预测。高压/特高压直流线路同塔双回架设时，因空间离子流场的相互影响，地面合成场强分布与塔型和导线布置方式有较大关系。±800 kV特高压直流线路位于上层、极导线采取+-/-+方式布置时，地面合成场强最大值相比采取-+/-+方式布置增加了17%；±800 kV特高压直流双极线路位于杆塔同一侧、极导线采取++/--方式布置时 ...

A more‐than‐human political ecology of Indonesian songbird trade
Conservation Biology, Volume 40, Issue 3, June 2026.Abstract Since its inception, conservation science has considered wildlife trade a problem. In focusing on conservation outcomes, conservationists almost completely ignore the welfare of traded animals and plants and the harms they endure. We developed a political ecology approach that incorporates the interconnectedness of people with animals and ...

Rare Metals, Volume 45, Issue 2, February 2026.ABSTRACT Photocatalytic molecular oxygen (O2) activation provides a sustainable approach to produce singlet oxygen (1O2) for organic contaminants detoxification. However, the charge carriers‐involved pathway usually suffers from unsatisfactory 1O2 production efficiency owing to energy loss caused by photogenerated hole‐mediated superoxide species (•O2−

Gaoya dianqi, 2023 换流站直流场内智能巡检机器人在场强较大区域中运行时出现过通讯中断、失控偏移等问题。为分析考虑离子流的合成电场对智能巡检机器人的影响，文中首先建立直流场三维模型，对不同运行工况下直流场区域的空间标称电场进行仿真分析；然后对直流场不同区域选取多个测量点进行合成电场实测，结合多点实测数据对仿真结果进行差分修正。最后根据修正后的空间电场数值，优化机器人的巡检路径，避开高场强区域。结果表明，巡检机器人在优化后的巡检路径上巡检，可以避开场强超过阈值的地方，降低了受干扰风险，提高了巡检的可靠性。

World Affairs, Volume 189, Issue 1, Spring 2026.ABSTRACT In the study, we investigate the roles energy price inflation and its volatility play in shaping foreign direct investment (FDI) inflow into Sub‐Saharan Africa (SSA). Applying data from 37 SSA economies between 2002 and 2023 and the system generalized method of moments (GMM) as the estimation strategy to account for endogeneity, the results ...

Gaoya dianqi, 2021 当±800 kV新东直流正常运行时,±800 kV昆柳龙线路与其部分线段并行,昆柳龙线路感应电压远远高于其他直流线路感应电压。文中利用有限元仿真软件建立新东直流和昆柳龙直流并行线段的二维仿真计算模型,仿真了新东直流输电线路带电运行情况下昆柳龙直流线路的感应电压特性。结果表明:柳北站—龙门站线路在静电场单独作用下,正极感应电压为6 kV,负极感应电压12 k V;在静电场与离子流场的合成电场作用下,正极感应电压为20.7 kV,负极感应电压30.5 kV,这与实际测量结果最高感应电压为42 kV较为接近 ...

Regulation &Governance, Volume 20, Issue 1, Page 35-63, January 2026.ABSTRACT Existing literature largely agrees that authoritarian regimes establish channels for political participation to gather valuable information on citizens' anti‐regime sentiments and policy preferences and to supervise lower‐level bureaucrats and firms.

Gaoya dianqi, 2014 直流输电工程与交流输变电工程不同,直流设备周围的电场为直流静电场和空间离子流场的综合场。但是,目前,国内直流输电工程的检修作业人员安全防护基本参照同等电压等级的交流输变电工程进行。当现场使用大型机具进行带电施工和检修时,由于机具的进入,作业现场的直流综合场和空间离子流分布会影响检修作业人员的安全防护效果。因此,笔者针对直流换流站的现场实际布置情况,对换流站典型施工区域有/无机具条件下的直流合成电场和离子流密度进行了测试。测试结果表明,有大型机具存在时,由于机具本体的屏蔽作用 ...
