Gaoya dianqi温度是影响气体绝缘金属封闭组合电器（GIS）中典型绝缘缺陷形成与发展的重要因素之一。为探究温度因素对盆式绝缘子缺陷电场分布的影响，文中利用有限元软件建立了252 kV GIS电—热—流多物理场耦合模型，得到了不同导体温度下、处于不同位置的气泡、裂纹及悬浮金属微粒缺陷下绝缘子表面的电场分布，并通过表面电荷分布与计算气体临界击穿场强进一步分析电场变化规律。结果表明：导体温度升高，3种缺陷下的绝缘子表面最大场强都随之增大，裂纹缺陷下增幅最大，悬浮金属微粒下最小。温度变化对电场的影响与绝缘缺陷类型、位置有关 ...

Gongye shui chuliA2/O是一种常见的生活污水处理工艺，其好氧段的曝气方式通常采用传统的底部曝气，溶氧效率较低。为了实现对污水高质高效的处理，基于气-液传质强化和流体力学理论，自主开发了一种无动力驱动静态螺旋切割器，可将气-液混合溶液中的大气泡切割细化成微纳米量级的小气泡，可在较短的时间内提高溶氧，且控制气体流量即可实现对溶氧量的调节。对无曝气、传统底部曝气采用静态螺旋切割进行对比实验，结果表明：与传统底部曝气工艺相比，静态螺旋切割对固体悬浮物（SS）的去除率提高了12.3%，对COD的去除率提高了5.6%，对氨氮 ...
