International Scholarly Research Notices, Volume 2013, Issue 1, 2013., 2013 The present study explored the time course of neighborhood frequency effect at the early processing stages, examining whether orthographic neighbors with higher frequency exerted an influence on target processing especially at the phonological stage by using the event‐related potential (ERP). Thirteen undergraduate students were recruited in this study,

Dianci bileiqi, 2023 高速铁路特殊运行方式会产生大量的谐波，谐波会通过牵引变压器传入220 kV侧高压电缆，在电缆护层上产生谐波电压，威胁电缆的安全运行。笔者在牵引变电所现场实测谐波数据的基础上，建立了基于实测数据的谐波源模型，解决了谐波源建模复杂的问题并能准确反映出高铁列车的实际运行状况。在此基础上仿真计算了高铁在牵引、再生制动和惰性3种工况下220 kV侧电缆护层谐波电压特性，探究了电缆长度、电缆接地方式、谐波电流参数等对谐波电压的影响规律。结果表明：高铁不同运行方式下，护层谐波电压均远超过工频正常运行情况 ...

Rare Metals, Volume 45, Issue 5, May 2026.ABSTRACT Integrating light emission and electromagnetic wave (EMW) absorption into a single material opens up possibilities for multienvironmental applications. Herein, we propose a novel “molecular engineering‐pyrolysis conversion” strategy to construct a bifunctional system with tunable photoluminescence and efficient EMW absorption performance.

China's Eco‐Civilisation, Climate Leviathan, and Hobbesian Energy Transition
Antipode, Volume 57, Issue 3, Page 830-861, May 2025.Abstract Scholars have hitherto tended to theorise China's ecological civilisation project either as a form of environmental authoritarianism or as a vision of eco‐socialism. This paper contributes to the conversation by conducting a textual analysis of Chinese scholarly discussions on eco‐civilisation.

Integrative Conservation, Volume 4, Issue 1, Page 10-19, March 2025.Brief summary: Urbanization is leading to “Nature‐deficit Disorder” that threatens children's health and the sustainable development of humanity. This study implements a new solution—the Mini Botanical Garden, which integrates some of the functions of botanical gardens into community green spaces to popularize nature education in the city.

Dianci bileiqi, 2012 电网电压谐波不仅对MOA泄漏电流中的容性分量带来干扰,而且对阻性分量也带来干扰。分析了电压谐波对两种基本方法-补偿法与谐波分析法的影响,并对补偿法进行了仿真计算,补偿法必须考虑容性谐波的干扰,谐波分析法避开了容性谐波的干扰,两种方法都不能消除阻性电流中直接来自电压谐波中的分量,综述目前已有消除电压谐波影响的方法,可根据阻性电流基波分量计算出阻性电流值及谐波分量,阻性电流中来自系统电压谐波干扰部分的消除还需进一步分析。

Gaoya dianqi, 2018 高速铁路特殊运行方式会产生大量的谐波,谐波会通过牵引变压器传入主网220 k V侧,对主网的影响值得深入研究。文中在牵引变电所现场测试谐波数据的基础上,建立基于实测数据的谐波源模型,通过仿真计算总结了高铁谐波对牵引变压器220 k V侧的影响规律。当高铁谐波传递至220 k V侧后,各次谐波有效值有不同幅度降低;谐波含有率也有不同的变化,3、5次谐波电流含有率均有增加,750次奇次谐波电流含有率均有所降低。当T线谐波电流相位与F线谐波电流相位的差值不同时,对220 k V侧影响也不同,当相位差在10 ...

Gaoya dianqi, 2016 分析了电容器噪声产生机理,利用10 kV电能质量谐波源试验平台,开展工频基波叠加不同畸变率谐波电压条件下并联电容器的噪声试验研究,得出不同次谐波时电容器噪声变化曲线,分析谐波对10 kV并联电容器的影响程度,针对典型条件下电容器噪声频谱进行分析。试验结果表明,基波叠加谐波的激励信号作用下,电容器噪声频率主要集中于基波二倍频率、h+1次谐波频率、h-1次谐波频率和2h次谐波频率特征频率上。
