, 2015 笔者读到《中国科技术语》2015年第1期赵中平的《mechanical properties中文译名演变过程及定义》一文,很受启发,但也有一些不同看法。该文斩钉截铁地说,"力学性能"并不存在,只有"机械性能",恐怕事实并不那么简单。问题的起源大概是对英文中mechanical和mechanics的理解。我们查找一本英文辞典(比如Webster’s New World College Dictionary ...

Gaoya dianqi, 2020 电力变压器是电网电力输送中的核心电气设备,合理评估变压器的性能对保证电力系统稳定运行意义重大。文中根据变压器故障的原因和评价指标来源,提出了基于定量修正层次理论的变压器性能评估方法。针对变压器性能评估指标体系中评价因素结构复杂、数量庞大的问题,首先依据指标体系中反映变压器故障的准确程度,筛选出能够反映变压器绝缘性能、油性能、过热性故障和放电性故障的关键指标,建立了变压器性能评估关键指标体系;其次利用层次分析法并结合定量修正评分函数,确定指标的最优权重,得到各指标的评分值 ...

The Impact of AI‐Assisted L2 Learning on Learners’ Emotions: A Meta‐Analysis
International Journal of Applied Linguistics, EarlyView.ABSTRACT The scope of research on AI‐assisted second/foreign language (L2/FL) learning has expanded beyond learning outcomes to focus on learners’ emotional experiences. Despite their proliferation, existing empirical findings are inconsistent, and few studies have systematically synthesized the impacts of AI‐assisted L2 learning on learners’ emotional

Dianci bileiqi为了解决±800kV特高压直流换流站EM避雷器故障频发的问题，需要系统开展EM避雷器的关键性能分析，发掘其性能薄弱点并提出性能优化建议。本文依托陕北站EM避雷器故障情况，通过解体故障避雷器元件并设置对照组，试验分析EM避雷器的密封性能、绝缘耐受性能、能量耐受性能、大电流冲击耐受性能和电流分布性能。试验发现单片电阻片的能量吸收能力满足技术规范要求并有一定裕度，但吸能后元件内部温度大幅升高，电阻片的侧面绝缘性能在高温下降低，最终发展成贯穿元件的闪络损坏 ...

International Journal of Applied Linguistics, EarlyView.ABSTRACT Collaborative writing has attracted increasing attention in English as a Foreign Language (EFL) instruction due to its potential to enhance learners’ writing competence. However, few studies have examined the comparative effects of collaborative versus independent writing on EFL learners’ individual performance, especially in higher‐order ...
