International Journal of Applied Linguistics, Volume 36, Issue 4, Page 3029-3039, November 2026.ABSTRACT This study examines how foreign language teachers’ beliefs about the medium of instruction and translanguaging evolve over time by revisiting three in‐service teachers twelve years after their initial interviews. Using a qualitative longitudinal design, the study traces how translanguaging was initially framed as pedagogically deficient but ...

, 2007 为了适应电子商务中迅速变化的流程环境和系统负载,需要在多个工作流引擎中分配工作量,以保证工作流引擎在高负载条件下可以保持一个可接受的性能。基于中间件技术的工作流负载平衡子系统是提供高可信赖性和高伸缩性的一种有效方法,但目前还存在许多不足,如没有从优先级的角度来区分流程,没有精确定义系统的负载,分析了工作流的主要特点,设计了基于优先级队列的,实现任务共享的,自适应负载系统,并通过实验定义了一个综合考虑系统处理能力和工作流负载特点的因子 ...

Shuitu Baochi Xuebao, 2020 三峡库区水土流失严重，开展水土流失综合治理是减少入库泥沙和提高三峡工程综合效益的关键，而如何高效识别优先小流域，则是提高治理资金效益和科学决策的基础。以重庆市合川区为例，在区域土壤侵蚀评价的基础上，提出了水土流失面积法、土地利用-水土流失面积法和坡度-水土流失面积法3种优先小流域识别方法，并对其进行了比较分析。结果表明，坡度-水土流失面积法识别的优先小流域水土流失面积占比接近于水土流失面积法，同时又将坡度较大以及耕地、园地和采矿用地面积占比较大的小流域识别出来，纳入优先小流域中 ...

Bidirectional Interfacial Chemical Regulation Enables Durable Aqueous Zn‐I2 Batteries
Rare Metals, Volume 45, Issue 10, October 2026.ABSTRACT Aqueous Zn‐I2 batteries hold great promise for large‐scale energy storage, yet their practical deployment is hindered by coupled interfacial instabilities at both electrodes, where Zn‐anode parasitic reactions and cathodic polyiodide shuttle mutually aggravate each other.

Rare Metals, Volume 45, Issue 9, September 2026.ABSTRACT Tin‐based composite oxides typically undergo severe volume variations and exhibit poor intrinsic conductivities despite their high theoretical capacity as promising anode candidates for sodium‐ion batteries. This results in rapid structural degradation and capacity fading upon cycling.

Shuitu Baochi Xuebao, 2016 为了研究崩岗侵蚀土壤的水分运动特征，采集湖北通城县花岗岩崩岗区的红壤，研究优先流及影响因子。把采集的1种红土层和3种砂土层按照野外“上红下砂”层次顺序，分别装填到长60 cm，宽11 cm，高110 cm的透明PVC土箱。3个土箱在不同初始含水量（12.2%～23.6%）和雨强（0.7，1.2 mm/min）下进行模拟降雨入渗，用时域反射仪（TDR）高频监测土体20个部位含水量瞬时动态，根据含水量的时空变化识别土体优先流发生特征。结果表明，降水入渗多表现为非均匀入渗，土壤饱和导水率较大 ...

Shuitu Baochi Xuebao, 2021 为了揭示喀斯特林下经济活动中人为踩踏对土壤入渗特性的影响规律，以喀斯特山地森林内部（未受干扰区域）、森林小径中央、森林小径边缘和裸地为试验样地，基于盘式入渗试验测定不同负压水头下（-0.5，-3，-6，-9 cm）的非饱和导水率（K9、K6、K3、K0.5）、饱和导水率KS、Gardner α常数和水流贡献率。通过原位染色示踪试验分别估算各样地的剖面染色面积比（DC）、均匀渗透深度（UniFr）和优先流百分比（PF-fr），分析了人为踩踏对喀斯特森林土壤优先流特征的影响。结果表明，森林小径中央的KS ...

Rare Metals, Volume 45, Issue 9, September 2026.ABSTRACT Aqueous zinc batteries hold great promise for large‐scale energy storage, yet their practical application is hindered by dendrite growth and interfacial side reactions on the zinc anode. Inspired by the industrially mature chromate passivation technology, this work reports an in situ construction of a chromium‐rich passivation layer (Zn@Cr) on
