Gaoya dianqi, 1998 针对电磁轨道炮炮膛导电轨道电极表面受高密度电弧烧蚀的现象,计算了电弧中带电粒子轰击电极表面时,传输给电极表面的能流密度。结果表明:电弧中带电粒子轰击电极表面时,将携带的热运动动能、鞘层电位差势能、离子复合能和冷凝热传输给弧根处的电极表面区域,是引起电极表面烧蚀、产生宏观熔坑的主要能量来源。

Dianci bileiqi, 2009 对复合绝缘子的电场和电位分布进行了研究,提出了优化复合绝缘子电场和电位分布的内电极和均压环配置法。该方法是在复合绝缘子的玻璃纤维芯棒两端内嵌细金属内电极;导线侧配置内电极和均压环,而杆塔侧仅配置内电极。在复合绝缘子的导线侧,内电极、金具和均压环之间形成低电场区,降低了该部分绝缘承担的电位分布。在杆塔侧,内电极与杆塔侧金具等电位,内电极所伸入、涵盖的绝缘处于内电极与杆塔侧金具形成的轴向低电场区,降低了该部分绝缘承担的电位;而内电极尖端及以下形成较高电场,抬升了内电极尖端以下的部分绝缘所承担的电压 ...

TiO2NTs/Sb-SnO2-Ni电极制备与电化学处理废水性能
Gongye shui chuli, 2018 采用阳极氧化法制备二氧化钛纳米管（TiO2NTs）电极基底，使用热分解方法制备了Ti/Sb-SnO2-Ni和TiO2NTs/Sb-SnO2-Ni两种电极。通过扫描电镜（SEM）、X射线衍射仪（XRD）、电化学工作站等分析仪器分别研究了基底对电极表面结构、组分和电化学性能的影响。采用阳极快速寿命测试法对电极进行寿命测试，并以亚甲基蓝为模拟污染物研究了电极的电催化性能。研究结果表明，TiO2NTs为基底可有效改善电极表面结构，从而提高电极的寿命和催化性能。相比平板钛基底 ...

Anode‐Free Alkali Metal Batteries Under Extreme Temperatures
Rare Metals, Volume 45, Issue 8, August 2026.ABSTRACT Anode‐free alkali metal batteries (AFAMBs) have attracted considerable interest as promising candidates for next‐generation energy storage systems, owing to their high energy density and simplified manufacturability. Extending their reversible and stable operation to low‐temperature (LT) and high‐temperature (HT) environments is crucial for ...
