Dianci bileiqi, 2019 雷电感应过电压导致配电线路发生跳闸或故障的比例要远高于雷电直击,因此需要分析采用线路避雷器对配电线路感应过电压的防护效果。利用EMTP软件编程计算线路雷电感应过电压,分析安装线路避雷器对感应过电压的防护效果,讨论雷电流幅值和雷击点距线路距离、避雷器安装间距、接地电阻对避雷器抑制感应过电压效果的影响。分析结果表明:配电线路安装线路避雷器后能够在一定程度抑制雷电感应过电压;雷电流幅值越高、雷击点距线路近,避雷器抑制感应过电压的效果越弱;避雷器安装间距影响对感应过电压的防护效果,安装越密 ...

MM-convex function & its Jensen-type inequality(MM-凸函数及其Jensen型不等式)
Zhejiang Daxue xuebao. Lixue ban, 2017 考虑函数的广义凸性问题，利用区间上的二元幂平均定义了MM-凸函数，讨论了MM-凸函数的若干判定定理及运算性质，建立了其Jensen型不等式，并给出了Jensen型不等式的等价形式及推论.结果表明，MM-凸函数是比较函数定义区间内任意两点的幂平均函数值与其函数值的幂平均大小所确定的各类凸函数的推广.MM-凸函数概念的引入，为深入研究凸函数和拓展凸函数概念探索了 一条新途径.
