Rare Metals, Volume 45, Issue 2, February 2026.ABSTRACT Developing low‐energy‐input electrocatalytic systems for efficient hydrogen production is crucial for advancing sustainable energy technologies. The overall hydrazine splitting (OHzS) has emerged as a promising strategy to reduce the overall energy consumption by replacing the sluggish oxygen evolution reaction.

Gaoya dianqi, 2018 文中描述了252 kV三相盆式绝缘子破坏水压试验的情况,为明确三相盆式绝缘子破坏水压不能满足标准要求的原因,首先对252 kV三相盆式绝缘子进行了建模、仿真与分析,明确了三相盆式绝缘子相间盆式结构交汇处应力集中是破坏水压偏低的原因。随后对模型进行了改进,将应力集中由‘Y’型分布转化为‘△’型分布,显著降低了最大应力值,显著改善了盆式绝缘子的耐压状态。最后讨论给出了252 kV三相盆式绝缘子在强度设计过程中应结合仿真计算进行机械强度设计的基本思想。文中的工作为三相盆式绝缘子的设计提供了一定的参考。

Zhejiang Daxue xuebao. Lixue ban, 2015 应用NCEP再分析资料，分析了2008年8号台风“凤凰”生成和发展过程中大尺度稳定凝结潜热、积云对流潜热和海面感热3种热力因子的作用.结果表明：对流凝结潜热释放是台风“凤凰”维持和发展的主要热力因子，积云对流潜热释放不但使台风中心增暖并使台风中间层上升运动增强，从而促使台风加强和发展；海面感热通过海气相互作用使海面凤及对流层涡度增强，可能是台风初始低压的形成机制；大尺度稳定凝结潜热在台风发展过程中虽然值较小，但其通过影响台风眼区的垂直下沉气流，可促使台风暖心低压进一步发展.
