Gaoya dianqi, 2015 红外测温技术具有不接触、不停运、不取样、检测速度快的优点,是绝缘子运行状态在线检测的重要方法之一。文中在绝缘子发热机理和红外热像技术的原理上,立足电力工作中零值和污秽绝缘子快速检测,分别对零值绝缘子位于绝缘子串不同位置时红外测温试验对比,以及对污秽绝缘子串与清洁串的红外测温对比,试验结果表明,当绝缘子串有严重污秽和零值绝缘子存在时,其热像表征图像发生明显的突变。此外,当零值绝缘子位于串中靠近高压端时,其热像图像显示零值绝缘子与相邻正常绝缘子平均温差最大,位于中部时与相邻正常绝缘子平均温差最小 ...

Review of Policy Research, Volume 43, Issue 2, March 2026.ABSTRACT This study applies the Narrative Policy Framework (NPF) within a non‐democratic context, exploring the role of policy narratives in the implementation of patient‐centred healthcare policy in China. Drawing on a dataset of academic journal articles that reference both “market” and “patient‐centredness,” the research reveals how local ...

People and Nature, Volume 8, Issue 2, Page 270-282, February 2026.Abstract Chinese consumer demand for ivory threatens vulnerable African elephant populations, despite long‐standing efforts to combat the illegal wildlife trade. Behavioural science approaches have been proposed to address these systemic behaviours. However, their robust use remains uncommon in demand management interventions.
