Gaoya dianqi, 2004 电力系统中使用真空断路器切除无功补偿用并联电容器时,容易产生重燃过电压,严重影响并联电容的安全运行。笔者对10kV系统中切除并联电容器时所产生的重燃过电压进行了模拟计算,着重分析了影响重燃过电压大小的因素,并研究了利用MOA对并联电容器进行过电压保护的效果。

International Journal of Applied Linguistics, EarlyView.ABSTRACT Research on English‐Medium‐Instruction (EMI) highlights inadequate support for students transitioning from L1‐medium‐instruction to EMI. To date, little research has focused on how L2 students’ adaptation to an EMI environment influences their L2 learning motivation (LLM).

Shuitu Baochi Xuebao, 2019 以紫色土为研究对象，通过室内重塑土试验，采用多元回归方程和曲面响应等分析方法，研究容重和含水率对紫色土崩解特性的影响。结果表明：（1）在相同容重下，崩解量随着含水率的增加而减小，不同含水率的土样崩解时间有所不同；土样完全崩解时间总体上随着含水率的增加而延长，且崩解量主要集中在崩解阶段前3 min。（2）在相同含水率下，崩解量随着容重的增加而减小，土样完全崩解时间总体上随容重的增大而延长，且崩解量主要集中在前4 min。（3）在相同容重和含水率下，土样崩解速率均随着容重和含水率的增大而减小；较之容重 ...

International Journal of Applied Linguistics, EarlyView.ABSTRACT This study examines multilingual practices in research interviews, focusing on English lexical insertions in Chinese‐language research interviews with teachers of Chinese in Australian secondary schools, and treating these code‐switches as analytically meaningful rather than incidental.

Shuitu Baochi Xuebao, 2020 土壤抗剪强度既可评价土壤侵蚀敏感性，也是反映耕层土壤耕作性能的重要参数。不同剪切方式下土壤抗剪强度指标存在一定差异，以紫色土坡耕地耕层土壤为研究对象，采用室内重塑土三轴及直剪试验方法，研究容重和含水率对紫色土坡耕地耕层土壤抗剪强度的影响，并分析了2种试验方法的差异性。结果表明：（1）紫色土坡耕地耕层土壤黏聚力（c）总体随容重（ρd）增大而增加，随含水率（w）增加而减小，三轴及直剪试验条件下黏聚力最大值均出现在容重1.4 g/cm3、含水率10%水平下，分别为32.33，21.78 kPa ...

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 ...

International Journal of Applied Linguistics, EarlyView.ABSTRACT Artificial intelligence (AI) is increasingly used to support language learning, yet little is known about how younger learners accept and engage with AI‐assisted reading. This study investigates primary school students’ acceptance of and engagement with an AI‐supported adaptive reading application for English as a Foreign Language (EFL ...

Shuitu Baochi Xuebao, 2011 采用经典统计学方法,通过网格布点,研究黄土高原坡地表层土壤水分和容重在降雨后不同时段的空间变异特征。结果表明:(1)降雨后第1天,表层土壤水分和容重的变异程度分别为中等、弱变异性;在各坡向间土壤水分呈阴坡>阳坡>山脊的变化趋势,容重为阴坡>山脊>阳坡;(2)降雨后第20天,土壤水分和容重的变异程度均保持不变,但土壤水分在不同坡向间的数量特征发生改变(阴坡>山顶>阳坡),而容重的变化趋势保持不变;(3)表层土壤水分具有弱的时间稳定性,而容重的时间稳定性较强。(4)相关分析表明,降雨后第1天 ...

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 ...
