Kongjian kexue xuebao为揭示微重力条件下PCM液桥相变过程流动特征及相变演化规律, 建立PCM液桥数理模型, 采用数值模拟的方法系统研究了不同工况下PCM液桥相变过程中固液界面的演化过程, 分析不同高径比和温差对液桥形状、固液界面演化规律、相变速度和热毛细流动的影响. 研究结果表明, 在大温差条件下热毛细流动更加强烈, 处于外部壁面处的相变材料的相变速度也会更快, 外壁处的相变界面与壁面的夹角会更小. 大的高径比条件下会有同样的效果, 同时也会产生更多的涡胞结构, 热毛细对流效果更明显.

Biomass‐Derived Laser‐Induced Graphene: From Precursor Chemistry to Device Integration
Rare Metals, Volume 45, Issue 10, October 2026.ABSTRACT Laser direct writing provides a mask‐free route for converting suitable carbon‐containing precursors into patterned, porous, and conductive laser‐induced graphene (LIG) networks. Although LIG was initially demonstrated mainly using aromatic synthetic polymers, such as polyimide, biomass precursors introduce renewable feedstocks with highly ...

Gaoya dianqi, 2014 电缆中间接头复合界面受潮是中压交联电缆的常见缺陷,在运行的过程中会导致界面表面电阻下降,进而产生沿面放电,逐渐降低电缆的绝缘性能,甚至直接导致电缆中间接头绝缘击穿事故,给电缆线路的安全稳定运行带来严重隐患。笔者根据电缆中间接头的结构特征建立了复合界面受潮缺陷的等效电路模型,仿真分析了不同程度受潮缺陷下,注入脉冲信号的时域反射波形图谱及其典型特征。提出了一种采用基于注入脉冲信号时域反射波法检测与定位电缆中间接头复合界面不同程度受潮缺陷的方法,并通过工业应用案例验证了该方法的有效性。
