ABSTRACT This paper examines the features of metadiscourse across different teacher moves in university linguistics classroom discourse and the teaching strategies reflected in its use. The results reveal that teachers employ diverse metadiscourse during classroom interactions to support student reasoning.

ABSTRACT Bangladesh's goal of achieving high‐income status by 2041 requires dependable, low‐emission, and affordable energy. With near‐universal grid coverage and increasing demand, nuclear energy is a strategic asset for long‐term baseload supply. However, the existing financing model, typified by the country's most expensive $12.65 billion Rooppur ...

Embracing the politics of transformation: Policy action as “battle‐settlement events”
Abstract Societal transformations for addressing climate change are intensely contested and at risk of resistance and backlash to ambitious policy action. But they are frequently modeled through heuristics such as S‐curves which abstract from such conflicts, assuming increasing returns to scale as a driver of transformations.

气体绝缘开关柜漏气问题是影响开关设备安全可靠运行的关键问题。笔者以AEⅡ-40.5型气体绝缘开关柜为例,针对气室接地穿墙绝缘子出现漏气的问题,通过对接地穿墙绝缘子各相关环节和要素的逐一分析判断的方法,最终判定:设备在抽气和充气过程中,由于气室的弹性变形所产生的对接地穿墙绝缘子的非正常作用力,是导致接地穿墙绝缘子损伤而漏气的真正原因。并采取了改变接地穿墙绝缘子的刚性连接为软连接的措施,从根本上消除了气室变形对接地穿墙绝缘子的影响,彻底解决了由于接地穿墙绝缘子损伤而产生漏气的问题 ...

Abstract As nations seek to expand protected area (PA) networks to cover 30% of land and seas by 2030 (30×30), there is an urgent need for systematic conservation planning and spatial prioritization that considers the broad range of ecological and socioeconomic factors influencing the persistence of biodiversity.

快速接地开关作为高压开关电器设备的重要模块,通常采用弹簧操动机构作为其驱动装置,降低机构驱动弹簧操作功,能够有效地减小传动系统所受的冲击载荷,对提高快速接地开关稳定性和可靠性具有重要意义。笔者通过建立快速接地开关三维模型,开展动力学仿真计算,对仿真数据进行分析,发现了驱动弹簧关键参数与快速接地开关合闸速度之间的对应关系,提出了一种驱动弹簧的优化设计方法,并通过样机试验验证了该方法的可行性。试验结果表明,该方法设计的驱动弹簧,既能满足合闸速度要求,又可实现驱动弹簧操作功最小化。

Clip Voice: Misogyny and the Renegotiation of a Gendered Vocal Style in Chinese Digital Discourse
ABSTRACT The participatory culture of social media allows women's voices to be heard but also parodied and policed. On Chinese social media platforms, where performers rapidly adopt and transform vocal trends for engagement, discourse on gendered vocal styles has proliferated.

Abstract Defined by threat, urgency, and uncertainty, crises produce opportunities for government leaders to exploit and create meaning around their policy decisions in such unstable circumstances. In narrating their preferred policy solutions, one of the tools governments can use is relying on evidence‐based information.

500/220kV同塔四回输电线路接地开关开合感应电压—感应电流能力研究
同塔多回输电线路有效解决了电网建设与输电走廊紧缺之间的矛盾,但对接地开关提出了严苛的要求。笔者以500 kV祯宝甲乙线与220 kV东莆甲乙线同塔四回架设为例,对感应电压和感应电流进行了理论分析,采用电磁暂态仿真程序(ATP-EMTP)计算了两种不同运行工况下,停运线路的感应电压和感应电流。发现计算结果超过了标准规定的接地开关能够开合的B类感应电压、电流的要求。依据计算结果对500 kV东莞站采用的220 kV JW6-252/J50型接地开关进行了开合超B类感应电压、电流的试验。在开断电磁感应电压2 ...
