A Mini Review of Scientific Designs of Dynamic Responsive Fluids in Battery Technologies
Rare Metals, Volume 45, Issue 1, January 2026.ABSTRACT Dynamic responsive fluids are emerging as transformative elements in the evolution of battery technologies, marking a pivotal shift from static passive designs toward systems that actively sense and adapt to their operating environments. By integrating dynamic responsive fluids, batteries can interact with both internal and external stimuli in

Beyond Motivation: Modeling the Predictive Role of L2 Pride in Informal Digital Learning of English
International Journal of Applied Linguistics, Volume 35, Issue 4, Page 1938-1952, November 2025.ABSTRACT This study investigates the role of second language (L2) pride—an understudied affective factor—in shaping learners’ language learning motivation and involvement with informal digital learning of English (IDLE). Drawing on questionnaire data from 1388 Chinese university EFL students, the study employs structural equation modeling to examine ...

‘How Does Living in Institution Impact Young Lives?’—Insights From Young People in Ci'aiyuan
Children &Society, Volume 39, Issue 4, Page 760-769, July 2025.ABSTRACT Institutional care often carries a negative reputation due to its perceived adverse effects on children and young people. However, it remains a significant form of alternative care in China. In Xiangxi, childcare institutions, known as ci'aiyuan, have been further expanding by involving wider populations in recent years.

Gaoya dianqi, 1996 零序电流互感器在电缆引出的开关柜中应用很广泛。 若它的安装、布置或接线不合理,将会导致正常运行中的断路器误动作,造成不必要的损失,本文提出了消除误动作的方法,以提高产品可靠性。 一、零序互感器选型 任何一种接地继电器使用的零序电流互感器的规格和型号要根据使用馈线的规格而定。 1)若馈线是矩形母线,则选用矩形零序电流互感器。 2)若馈线是电缆线或软导线应选用环形零序电流互感器,对于不同的输出电缆线应根据以下因素选择不同规格。 （1）电缆绝缘层有的是热熔塑胶、有的是橡胶包皮,绝缘不同其外径也不同。 （2 ...

Social protection and resilience in protracted crises
International Social Security Review, Volume 78, Issue 2-3, Page 173-190, April-September 2025.Abstract This article critically examines perspectives on social protection’s role in strengthening resilience capacities in protracted crises – contexts where conflict and displacement persist for five years or longer. These crises shape how stakeholders navigate their mandates to provide support, while influencing how affected communities seek to ...

Dianci bileiqi, 2015 目前国内500 k V及以上交流超、特高压输电线路大多采用一根钢绞线（GJ地线）和一根光纤复合地线（OPGW）的架设方式。多采用GJ地线分段绝缘、一点接地,OPGW逐塔接地的方式。实际运行经验表明,GJ地线分段绝缘、一点接地不仅电能损耗小,而且并不降低地线的保护性。而OPGW逐塔接地的接地方式在保证通信连续的同时带来地线环流大、电能损耗较大等问题。因此,需要对地线不同接地方式下的感应电量的影响因素进行深入研究。本文以浙江一条运行中500 k V交流输电线路为研究对象,运用电磁暂态计算程序EMTP ...

Dianci bileiqi, 2020 输电线路覆冰严重影响电力系统安全运行,由于架空地线的悬挂点高于相导线,所处的环境温度低,同时没有运行电流等原因,在相同覆冰段下比其它导线覆冰更为严重。目前,大电流融冰技术是防治导、地线覆冰的最为有效的措施之一,由于架空地线的特殊结构,在开展大电流融冰之前,需对其进行绝缘化改造,但地线在绝缘化改造后的感应电压不仅影响到输电线路的安全运行和防雷效果,也是融冰电压和并联间隙选取的关键因素。笔者以500 kV同塔双回架空输电线路为例,在ATP-EMTP中建立了仿真模型 ...
