Traditional lightning protection measures can not solve the problem of superimposed lightning strikes.This paper presents a compressing arc extinguishing lightning protection device,which can solve the problem of superimposed lightning strikes.This device can extinguish the power frequency continuous current arc quickly in 1-2 ms.It is far less than the response time of relay protection,which can avoid lightning trips and improve the reliability of power supply.The computer simulation and engineering practice show that the compressing arc extinguishing device has good protection effect on superimposed lightning strikes.

0 引言rn红锥( Castanopsis hystrix)又名赤黎、红黎,是壳斗科的常绿乔木,是我国南方地区的珍贵树种,具有生长速度快、树干通直、材质优良的特性,是国家战略储备林和生态公益林的重要组成树种.发展红锥对提升我国优质木材战略储备能力和建设生态宜居的粤港澳大湾区具有重要的作用,目前红锥已成广东省重点发展的优良用材树种.但红锥造林主要使用天然林中收获的种子,造成单株差异明显,制约了林地生产力的提升,因此,本文结合广东省龙眼洞林场调查收集南方六省区红锥优良种质资源数据信息,整合当前最优良的遗传资源
黑龙江省东部那丹哈达增生杂岩主要由晚三叠世—中侏罗世含放射虫硅质岩组成,并夹有镁铁-超镁铁质杂岩和晚古生代浅海沉积岩.对黑龙江省东部石场、勤得利和胜利农场地区硅质岩分析显示,样品Al2O3、TiO2、CaO、Al2O3/(Al2O3+TFe2O3)及ΣREE整体上偏低,具有较高的SiO2含量,为纯硅质岩.结合Al-Fe-Mn三角图和K2O/Na2O值,表明该地区硅质岩的形成过程与海底热液作用无关.元素判别图解及地球化学特征揭示,黑龙江东部三个地区的硅质岩形成于大陆坡及边缘海环境.

内存地址翻译一直是影响计算机性能的重要因素之一,在虚拟化环境中由于存在多级地址翻译,这一问题更为突出.使用透明大页(THP)是优化这一问题的常见手段.本文以龙芯3 A4000处理器和KVM虚拟机为实验平台,分析了MIPS VZ环境中虚拟机使用透明大页的性能.发现透明大页在应用中存在分组TLB负载不均衡,使得部分场景中透明大页对性能产生了负面影响.本文对现有KVM内存管理进行了改进.通过在内存管理中增加对分组TLB负载的考量,提升了KVM虚拟机使用透明大页的性能.该方法对其他使用TLB分组结构的处理器也有参
