Comprehension of implied meaning in Chinese second language listening

open access: yesForeign Language Annals, EarlyView.
Abstract Listening comprehension is crucial for second language (L2) communication and acquisition. However, it has received less attention than reading, given the transient nature of speech signals and the intangible cognitive processes involved in it.

Reconceptualising Motivation as Material‐Semiotic Entanglements: Translanguaging in Graduate TESOL Education

open access: yesInternational Journal of Applied Linguistics, EarlyView.
ABSTRACT Multilingual students in Anglophone universities often operate in survival mode. While translanguaging supports learning, critical gaps remain in understanding how translanguaging pedagogies transform and sustain motivation in English‐dominant contexts.

土壤水分对植物根-土界面相互作用特性的影响

open access: yesShuitu Baochi Xuebao, 2018
为研究不同土壤水分下不同植物根系与土壤界面的摩阻特性,使用直剪仪对内蒙古中西部的5种典型乡土植物(柠条、沙棘、杨柴、紫花苜蓿和沙打旺)的根系在不同土壤含水率下进行根-土界面直剪摩擦试验。结果表明:当土壤含水率在4.5%~24.5%时,5种植物根-土界面摩擦系数均大于素土的土-土界面的值,且随着土壤含水率的增加,根-土界面和土-土界面摩擦系数均呈下降趋势,其中沙棘根-土界面的摩擦系数和黏聚力均大于其他4种植物的值,表明仅从根系与土壤间的相互作用特性来看,沙棘根系固土抗蚀的作用明显优于其他4种植物。根 ...

Cantonese (Dis)investment by Cross‐Border Postgraduates in Hong Kong: Negotiating Competing Capitals and Multiple Identities Among Neoliberal Subjects

open access: yesInternational Journal of Applied Linguistics, EarlyView.
ABSTRACT One key strategy that local universities and the government of Hong Kong have adopted in recent years is attracting more students from Chinese Mainland to study at Hong Kong's higher education institutions and contribute to society after graduation.

坡面细沟流侵蚀临界条件研究

open access: yesShuitu Baochi Xuebao, 2004
从适用于陡坡的水动力学模型出发,研究坡面水流细沟侵蚀临界状态的判断方法。讨论了坡长、坡度、坡面投影长对细沟侵蚀的影响,采用临界摩阻流速随坡度变化、临界摩阻流速不随坡度改变两种假定分别进行模拟计算,以摩阻流速作为判别坡面细沟流侵蚀临界状态的水动力学指标,在给定的坡面尺寸、净雨强和初始微地形条件下,计算得出了细沟流摩阻流速达到临界值时所对应的坡度。

支柱式绝缘子的粘结层脱粘失效仿真分析

open access: yesDianci bileiqi, 2016
采用基于内聚力裂缝模型(CCM)的有限元分析方法,模拟支柱式绝缘子的不同结构界面的力学特性,仿真再现了绝缘子受弯矩外载下界面脱粘失效的过程,并研究了粘结界面力学性能对绝缘子整体承载力的影响。分析表明,粘结层开裂过程可分为界面承载、界面开裂和裂纹扩展3个阶段;水泥粘结剂与金属基座的粘结层开裂时间早、脱粘速度快是绝缘子结构的薄弱环节;界面刚度、断裂能、极限强度的增加均能有效提高绝缘子的结构承载力,但随着承载力增加,破坏模型由界面脱粘变为水泥粘结剂受拉破坏。

运行复合绝缘子芯棒-护套界面性能评估

open access: yesDianci bileiqi, 2022
芯棒-护套界面性能是表征复合绝缘子运行状态和老化进程的重要对象之一。为准确评估宁夏地区运行复合绝缘子的芯棒-护套界面性能,对宁夏电网运行6年及以上、35 kV~750 kV的33个厂家批次复合绝缘子进行剖检试验和带护套芯棒水扩散试验,并对水扩散试验结果不同的试品做傅里叶红外光谱分析。结果表明,在密封性能良好的情况下,有23个厂家批次复合绝缘子的芯棒-护套界面粘接性下降、耐水解及耐湿热老化性能下降;相同运行环境下复合绝缘子芯棒-护套界面的老化进程与伞裙表面的老化进程不一致;复合绝缘子芯棒 ...

Transnationalizing Raciolinguistics: An Intersectional Analysis for Understanding Chinese International Students’ Language Ideologies Across Contexts

open access: yesJournal of Sociolinguistics, EarlyView.
ABSTRACT This study adopts a transnational raciolinguistic perspective to examine how Chinese international students (CISs) navigate language, race, and identity across borders and contexts. Based on semistructured interviews with 14 CISs, the study highlights that pre‐migration socialization in China influences how CISs perceive and interpret their ...

复合绝缘子护套与芯棒界面粘接性及界面质量检测方法研究

open access: yesGaoya dianqi, 2016
为有效评价复合绝缘子护套与芯棒的界面质量,文中首先提出了一种护套—芯棒压剪试验方法,通过检测护套与芯棒的界面粘接强度对界面粘接性进行评判。对3支运行复合绝缘子不同位置的试样分别进行护套—芯棒压剪试验和解剖试验,结果表明护套—芯棒压剪试验可以有效检测护套与芯棒界面的粘接性。进一步研究护套与芯棒界面质量的检测方法,对水煮后的带护套芯棒试样先后进行改进的水扩散试验和护套—芯棒压剪试验,结果表明界面泄漏电流值和界面粘接强度,可以分别反映护套与芯棒界面的缺陷和粘接性。研究说明结合改进的水扩散试验方法与护套 ...
