Gaoya dianqi, 2014 笔者针对紧凑型集合式并联电容器的特点,对YN接线的集合式电容器本体放电试验、温升试验、装置温升试验、放电线圈的误差试验、感应耐压试验和二次端子对地耐压试验等进行分析。通过对放电试验的分析,提出放电试验应该分相进行,不能三相并联进行的结论。通过对本体和装置温升试验的分析,提出了在目前条件下对电容器本体和装置进行温升试验的可行的试验方法。根据试验结果,得出放电线圈的误差试验应该在其安装在电容器内部后进行,对于集合式电容器的二次端子,应该再次进行对地耐受电压试验,放电线圈的其他试验可以用其安装前的试验来代替。

Basic income trials and the politics of scale: A research agenda
Policy Studies Journal, EarlyView.Abstract The growing popularity of basic income has led to extensive trials of the policy in numerous settings across the world. However, analysis of the politics of basic income, and in particular the political dynamics preceding and resulting from trial programs, lags. In response, we propose a research agenda that uses political scale to investigate

Powerful representation of the poor? German welfare associations' narrative advocacy during COVID‐19
Policy Studies Journal, EarlyView.Abstract The COVID‐19 pandemic sparked unprecedented experimentation in the German social assistance system, leading to changes previously considered impracticable by policymakers. This included a sanctions moratorium, easier access to benefits, and temporary cash transfers, all of which were advocated by welfare associations—key organized interests ...

Test and Research on the Rheological Damage Properties of Sandstone under Dynamic stress field-Seepage field coupling [PDF]
, 2016 机械振动、交通荷载、地震等产生的动应力场与降雨等因素所产生的渗流场耦合，会加快软岩的流变损伤，导致滑坡、崩塌、泥石流等严重的地质灾害。因此，加强对动应力场-渗流场耦合作用下软弱岩体的动态流变损伤特性的研究具有重要的理论和实际意义。论文以软弱砂岩为研究对象，利用重庆大学煤炭灾害与控制国家重点实验室的RLW-2000M煤岩三轴流变试验机研究了砂岩在动应力场-渗流场耦合作用下的动态流变损伤特性。具体的研究内容如下： (1)通过采集-钻芯-切割-打磨-浸泡等过程制备饱和的砂岩试样，根据砂岩试样的全应力 ...

Review of Policy Research, EarlyView.ABSTRACT Public appointments shape the top‐level bureaucracy by serving as a gateway for professionals with different profiles, chosen based on different criteria. In general, the literature has been more interested in analyzing appointments based on merit or sponsorship, based on verification of loyalty to the government or technical competence ...
