Dianci bileiqi, 2022 近年来我国复合绝缘子由于芯棒发热导致异常温升的故障时有发生,给电网安全运行带来隐患。为了研究芯棒发热的热传导特性,以及复合绝缘子内外温度的关系,笔者通过理论推导,建立了芯棒发热的热传导模型,并开展仿真与实验研究。结果表明,当复合绝缘子芯棒发热时,硅橡胶护套中径向温度成对数分布,芯棒表面温度与护套表面温度为一次函数关系,并且复合绝缘子内外温差与复合传热系数成正比,与护套导热系数和环境温度成反比,而环境湿度对复合绝缘子芯棒发热的热传导没有明显影响。仿真与实验结果相吻合,验证了热传导模型的准确性。

Rare Metals, Volume 45, Issue 7, July 2026.ABSTRACT In electrocatalysis, traditional single‐atom catalysts (SACs) face challenges in achieving coordinated control of reaction pathways due to limitations such as single local energy levels and carrier recombination. By introducing an additional defect structure, it is possible to break the electronic structure symmetry, thereby activating SACs ...

Mechanoluminescent Mixed‐Anion Borate Sr2B5O9Cl:Eu for Dynamic Anticounterfeiting
Rare Metals, Volume 45, Issue 7, July 2026.ABSTRACT Mechanoluminescence (ML)—the emission of light in response to mechanical stimuli—offers a direct and visually intuitive route for transducing mechanical information into optical signals. Herein, we report a mixed‐anion strategy to prepare mixed‐anion borate Sr2B5O9Cl:Eu phosphors through a facile, low‐temperature, and ambient‐atmosphere solid ...

Zhongshan Daxue xuebao. Yixue kexue ban, 2016 摘 要: 【目的】 探讨阵发性房颤患者P波时限对射频消融术后复发的预测意义?【方法】 171例行环肺静脉隔离术的阵发性房颤患者,描记术前及术后心电图,测量Ⅱ?Ⅲ?aVF?V1导联P波时限,计算P波时限变化值? 【结果】 Ⅱ?Ⅲ?Ⅵ导联术后P波时限均小于术前(P < 0.001)?依据随访情况,患者分为复发组32例及未复发组139例?复发组较未复发组在Ⅱ?Ⅲ?Ⅵ导联具有更小的P波时限变化值(P < 0.01),两组术前?术后P波时限及其他临床指标无统计学差异;多因素分析显示更小的Ⅱ导联P波时限变化值(P <
