Dianci bileiqi, 2013 为了更好的解决接地网散流、均压以及降阻问题,对圆环形接地网的均压特性及接地电阻进行了研究,并与传统的方形地网进行比较,采用电磁暂态仿真程序（ATP）对不形状的接地网,在雷电冲击作用下的电压大小进行仿真,以及对同一地网雷电流入地点不同时,入地点处的电压大小进行了仿真分析。结果分析表明:周长相同的圆环形地网与方形地网相比,圆环形地网的接地电阻比方形地网的小,并且雷电流入地点处的电压只有方形地网的一半左右,散流效果比方形地网好。在同跨度下,圆环地网的跨步电压也明显小于方形地网,均压效果好 ...

Carbon‐Insertion‐Engineered WS2 Hierarchical Heterostructure Enabling Superior Sodium‐Ion Storage
Rare Metals, EarlyView.ABSTRACT Tungsten disulfide (WS2) is considered a promising anode material for sodium‐ion batteries (SIBs). However, its practical application is hindered by poor electrical conductivity, large volume changes during cycling, and sluggish ion diffusion kinetics, which lead to unsatisfactory electrochemical performance.

The effect of mesoscale mountain in the boundary layer of the tropical cyclone(中尺度地形对热带气旋边界层的影响)
Zhejiang Daxue xuebao. Lixue ban, 2010 基于梯度风动量近似理论,考虑气压梯度力、科氏力、湍流摩擦力、离心力和惯性偏差力5力平衡,得到了柱坐标系下具有热带气旋边界层特征的解析解.并着重讨论了三维钟型孤立地形及二维钟型地形对径向速度、垂直水平流场及垂直速度场的影响.对于数值解的再现表明,热带气旋内边界层的运动同时受到湍流摩擦作用与地形作用的共同影响,二维钟型地形比三维钟型孤立地形对于垂直速度场、径向速度场及流场有更明显的影响.而热带气旋中心与地形中心的不重合会产生风场的不对称结构,且会在地形西北侧形成“偶极型”的垂直速度.
