Highly pathogenic avian influenza(HPAI)subtype H5Nx viruses have spread globally and are a major concern for poultry,wild birds,mammals,and even humans(de Vries et al.2015;Zeng et al.2022).The hemagglutinin(HA)genes of H5 subtype viruses have evolved into multiple clades and some of these clades have been further divided into subclades(Cui et al.2022).Clade 2.***.4.4H5N8 HPAI viruses(HPAIVs)have caused several waves of disease outbreaks in wild birds and domestic poultry(wang et al.2022).

以白刚玉和活性氧化铝粉为主要原料、鳞片石墨与炭黑为碳源、碳化硼与单质硅粉为添加剂、短切碳纤维为增强体制备了铝碳耐火材料。利用场发射扫描电子显微镜研究了材料中碳纤维与单质硅反应后发生的结构演变。结合三点弯曲法和单轴压缩法研究了材料不同温度下的力学性能,采用水淬冷法研究了材料的抗热震性能,采用单边切口梁法研究了材料的抗断裂性能。结果表明:热氧化可以有效对碳纤维表面进行改性,从而影响到碳纤维的结构演变与使用性能;合适的热氧化处理可使碳纤维在铝碳耐火材料中发挥显著的增强作用,加入500℃热氧化的碳纤维后,铝碳耐火材料的常温抗折强度、常温耐压强度和高温抗折强度相比于对照材料分别提高了28.2%、22.4%和87.2%(材料1 400℃热处理后)。另外,引入热氧化碳纤维也能对铝碳耐火材料的抗热震性能与抗断裂性能产生影响。

针对国家电网“六统一”线路保护装置,提出了超、特高压交流线路反时限零序过流保护的整定原则。反时限零序过流保护在保证灵敏性方面并无困难,整定原则的核心问题是解决选择性和速动性的矛盾。根据该保护的原理和逻辑提出了转折电流的概念以及接地距离保护与反时限零序过流保护的配合原则;充分考虑配合时间定值和最小时间定值对保护动作特性的影响,综合超、特高压电网实际短路电流水平和接地距离保护的过渡电阻耐受能力,将反时限零序过流保护低电流区的选择性与接地距离保护高电流区的选择性进行结合,提升了对接地故障全域电流范围的选择性切除能力;提出了方向元件投退原则。通过对某省级电网进行算例分析,验证了整定原则的有效性,该整定原则已经在实际电网中进行了应用。
