Passing on the red genes: Communism nostalgia in online fictions and ideological governance in China
Abstract How does communism as an ideology fare in the post‐reform digital age China? What are the implications for China's ideological governance? Through online ethnographic work and text analysis, this paper identifies and analyzes how communism as an ideation and a practice is (re)memorized, (re)presented, and (re)interpreted in popular online ...

交流滤波器回路是特高压换流变电站的重要设备回路,但其特殊的结构特征导致其在强震作用下易发生破坏。为研究交流滤波器回路的地震易损性,文中通过有限元数值仿真计算的方法,对某800 kV换流站交流滤波器回路进行了数值建模,基于数值模型进行了模态分析和地震响应时程计算,并进行了回路地震易损性分析。结果表明:交流滤波器回路中的高压电容器和电阻器支柱绝缘子根部应力水平较高,有破坏风险;软母线的轴拉力远低于其计算拉断力;考虑母线耦联作用后,高压电容器和电阻器等应力较高的设备地震响应有所降低;PGA高于0.4g时 ...

文中对国家标准《GB 1984—2014高压交流断路器》及《GB/T 4473—2008高压交流断路器的合成试验》、国际短路试验联盟STL导则中关于三相全电压关合的内容进行了解读,通过对直接试验回路中三相全电压关合过程进行模拟明确关合过程中断路器两端电压和电流波形的变化,对两种合成关合试验回路进行模拟分析并比较,提出了一种便于实现且等价性较好的三相全电压关合试验回路。结果表明该回路与目前标准推荐回路相比,实现难度较小,笔者推荐实验室可选择该试验回路。

断路器机构自带完善的控制回路,与断路器保护操作箱功能上存在重复、冲突,如果配合不好,会影响断路器以及电网安全稳定运行。笔者对机构操作回路和保护操作箱在防跳回路、跳合闸压力闭锁以及非全相保护回路的特点进行了分析总结,对改进两者在这些回路的配合方面进行了研究,提出在机构箱防跳回路中串联"就地/远方"切换把手ZK的接点;压力低禁止跳闸、禁止合闸、禁止操作等功能由断路器本体实现,压力低闭锁重合闸回路只选用第一路操作电源;以及采用断路器本体非全相保护,基于电气量的非全相保护作为补充之用 ...

Influences on cannabis policy design and adaptation in the American states
Abstract Despite federal prohibitions, three‐quarters of states had implemented medical marijuana laws (MML) and one‐third had implemented recreational cannabis laws (RCL) by 2020. State policy designs varied considerably, and we focus on policy development and maturation in policy implementation, examining factors influencing design features of policy

The Spiritual Path of Transformation1
Abstract Transformation is an essential component of individuation; it is not a linear but a circular process, encompassing experiences of standstill and deadlock where no longitudinal continuation is visible. Jung describes transformation in alchemical terms as a shared dialectical “reaction” between patient and analyst.

交流1000kV与500kV/220kV同塔四回线路的潜供电流问题研究
同塔四回线路回路多、间距小,线路间电磁耦合作用更强,使得潜供电流问题更加突出。针对这一问题,分析了同塔四回线路潜供电流产生机理,采用电磁暂态仿真软件ATP-EMTP建立了交流双回1 000 kV和500 kV/220 kV线路同塔四回线路的模型并计算得到多种运行方式下各电压等级线路的潜供电流与恢复电压。结果表明,500 kV/220 kV线路对1 000 kV线路潜供电流及恢复电压影响较小,但1 000 kV线路对500 kV/220 kV线路影响较大。在此基础上提出各电压等级线路的单相重合闸的推荐时间。
