Dianci bileiqi, 2004 对特殊参数的组合波发生器进行研究。首先讨论了波形参数、电路参数、电源利用率等之间的关系并得出有实用参考价值的曲线,根据此曲线,可以方便地确定特殊参数组合波在不同虚拟阻抗下的电路参数;其次,针对有代表性的电路（如10/1000电压波、10/1000电流波以及10/700电压波、10/300电流波等）,选取一定虚拟阻抗下的电路参数,并进行仿真,验证了理论计算的正确性。

International Journal of Applied Linguistics, EarlyView.ABSTRACT This article examines the language life of young Malaysian Chinese immigrants in Australia and their construction of multi‐membership as reflected in their daily language behaviors. It develops the concept of everyday linguistic citizenship and uses this concept as a theoretical lens to understand how the young adults build, maintain, and ...

New Phytologist, EarlyView.Biosynthesis and accumulation of tanshinones in the periderm of Salvia miltiorrhiza during secondary root growth. Summary Perennial herbs develop long‐lived roots that undergo repeated cycles of secondary growth, during which the periderm functions as a protective barrier and a major site of specialized metabolite accumulation.

Accountability in Government Use of AI: Citizen Concerns and Preferences
Public Administration, EarlyView.ABSTRACT Government adoption of AI opens the “pandora's box” of accountability, a core aspect of public value. Despite the centrality of governmental AI accountability, citizens' concerns and preferences in holding governments accountable for AI usage remain poorly understood.

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

Gaoya dianqi, 2018 整理了广东地区和华北地区的现场电力变压器实测色谱数据,根据数据特点选择相应的抽样方法,获得了各气体参量的数据样本。运用统计学中的非参数统计的方法对样本数据进行非参数检验,检验结果是各气体参量基本服从对数正态分布或者韦伯分布,同时获得了各气体参量所服从的各分布的分布函数以及相应的90%及95%分位点注意值。其中95%分位点注意值比国标和IEC中给出的气体参量注意值小,从而减少了对变压器故障的漏判。

Scientists in power plays: How substantive were scientists' narratives during the COVID‐19 pandemic?
Policy Studies Journal, EarlyView.Abstract Scientists who provide expert advice must engage with policy processes. Little is known about whether and how scientists deal with the political dynamics of policy processes that are inherent to policymaking. We study this question by building on the policy dimension concept within the Narrative Policy Framework.

Policy Studies Journal, EarlyView.Abstract We examine whether and how public participation in policymaking contributes towards fostering stakeholder support for policy proposals formulated in the bureaucratic arena. We explain how key markers of procedural fairness describing both the participation process and policymakers' presentations of it during the decision justification stage co‐

Policy Studies Journal, EarlyView.ABSTRACT Despite extensive research on policy diffusion, the ways in which policy attention influences this process remain underexplored. This study addressed this gap by distinguishing between three types of policy attention—political speeches, policy issuance and field visits—and investigating their differential impacts when delivered by central and ...
