International Journal of Applied Linguistics, EarlyView.ABSTRACT In English medium instruction (EMI), students face cognitive and emotional demands in second language (L2) communication, which may hamper their motivation and willingness to communicate (WTC). Adopting a mixed‐methods design, this study explores how growth mindsets affected student motivation (e.g., ideal L2 self and ideal disciplinary self ...

International Journal of Applied Linguistics, EarlyView.ABSTRACT While English‐medium instruction (EMI) and English for Academic Purposes (EAP) courses are designed to promote language and content learning, their prevailing English‐only approaches often undermine students’ learning motivation. Against this backdrop, translanguaging has gained recognition as an effective pedagogical practice to support ...

基于主成分分析和反向传播神经网络相结合的金属氧化物压敏电阻故障诊断分析
Dianci bileiqi, 2019 准确诊断金属氧化物压敏电阻故障对电力系统安全运行十分重要。为有效提高故障诊断率,本文提出基于主成分分析与反向传播神经网络相结合的故障诊断算法。对于MOV故障数据指示指标,利用主成分分析进行降维,降低原始指标间相关性,最后利用反向传播神经网络对所选主成分进行诊断。试验结果表明:相对于反向传播模型,PCA-反向传播模型诊断误判率下降了3%,模型运行时间降低了267 s。有效降低MOV误判率,简化了反向传播网络结构,提高网络收敛性和稳定性。

野生动物学报, 1997 本文通过粪便分析对甘肃兴隆山保护区食肉兽的食性及与马麝的关系进行了初步研究．粪便直径分析表明，该地区食肉兽主要为狐和豹猫．粪便内含物分析结果表明，啮齿类和鸟类出现的频率分别为８１．６％～８８．４％和２１．１％～３８．６％，马麝成体在４～５月很高（１７．６％），幼麝在出生期高达２１．１％．分析认为兴隆山食肉兽对马麝的捕食主要在马麝的幼仔期．

Gaoya dianqi, 2022 针对网内发生的一起罐式断路器故障，文中通过对断路器故障情况及回路电阻、机械特性、X射线数字成像检测等试验情况进行分析，判断故障的原因为静主触头触指存在弯曲异常导致合闸后接触不良。解体分析确定故障根本原因是多次操作后断路器静主触头与动主触头出现对中不良的问题，对中不良引起动主触头与静主触头产生碰撞，导致静主触头部分触指向内弯曲，最终因接触不良造成罐式断路器发生外壳烧穿等故障。为消除隐患，最后文中从产品结构、工艺控制两方面对设备故障的原因进行了深入分析，提出了相应的实用改进措施，避免类似故障再次发生。
