A Brief Analysis of the Acrostic in Chinese Language in Teaching Chinese as a Foreign Language [PDF]
, 2014 Acrostic is a special phenomenon of the modern Chinese language. It is a combination of lexical and syntactical that across “vocabulary” and “grammar” categories.

Study of GHz Surface Acoustic Wave Humidty Sensor Using Nanostructured Materials [PDF]
, 2016 随着物联网应用的不断扩展，需要大量传感器节点组成无线传感网络以实现未来万物互联的目标。其中，湿度测量器件在智能家居、气象、工业控制等领域是最为广泛和基础的传感器节点。为了实现无线传感网络，现有的电阻、电容型传感器件需要独立的电源系统持续供电，而在电池容量有限的条件下，器件需要采用占空比方式工作，即在高功耗的传感工作状态之间加入待机模式，以减小传感器节点的总功耗。由于待机模式的存在，无法对整个环境状态进行实时、无缝的检测，且由于构成节点的传感元件一般属于相对高功耗的器件，电池寿命始终有限。声表面波 ...

Rare Metals, Volume 45, Issue 5, May 2026.ABSTRACT Integrating light emission and electromagnetic wave (EMW) absorption into a single material opens up possibilities for multienvironmental applications. Herein, we propose a novel “molecular engineering‐pyrolysis conversion” strategy to construct a bifunctional system with tunable photoluminescence and efficient EMW absorption performance.

Dianci bileiqi, 2021 为准确获取不同温度条件下胶浸纸套管绝缘性能变化规律,在高低温试验箱中开展了±100 kV穿墙套管在不同温度下的频域介电谱测试,获得了被测试套管的绝缘电阻、工频介损、工频电容量等绝缘特征参数。研究结果表明:胶浸纸套管各绝缘性能参量对温度变化的反应较为敏感,工频介损因数随温度的上升呈现先减小后逐渐增加的趋势;绝缘电阻随温度的升高逐渐减小,且减小幅度较大;在低频区域,胶浸纸套管的介损随温度的升高逐渐增大,高频区域相反,介损频域谱随温度的升高整体向高频方向移动;胶浸纸套管的复电容实部在高频段基本保持不变,C ...

International Journal of Applied Linguistics, Volume 36, Issue 2, Page 979-994, May 2026.ABSTRACT Previous research has established the relationships between motivation, anxiety, teachers’ support, and self‐regulated learning (SRL) in English‐as‐a‐foreign‐language (EFL) learning. Most of the studies, however, have taken a variable‐centered approach in addressing the variable correlations, while learners’ characteristics and variable links ...

Attainment Pairing Effects on Cognitive Conflict in Technology‐enhanced EFL Cooperative Tasks
International Journal of Applied Linguistics, Volume 36, Issue 2, Page 1594-1605, May 2026.ABSTRACT This study examines how attainment pairing (high‐high versus high‐low versus low‐low attainment) impacts English as a Foreign Language (EFL) learner engagement during technology‐enhanced cooperative writing tasks. Seventy‐eight Chinese university learners formed 39 dyads (13 pairs per group) via Tencent Meeting.

Gaoya dianqi, 2005 研制了宽带和窄带两种超高频外置天线传感器,两种传感器增益均大于1,驻波比在其有效带宽范围内均小于2,均能用于GIS局部放电超高频检测。设计了高性能放大器和半分布参数超高频滤波器,工作频带为300～1000MHz,完全覆盖了两种传感器的工作频带。性能测试表明,传感器和滤波放大器性能优良,频率匹配,能满足超高频信号检测预处理的要求。通过对绝缘子表面金属污染缺陷产生的局部放电信号进行检测研究表明,超高频检测系统能够检测到超高频段微弱的局部放电信号,并能抑制低频段干扰,为后续模式识别的研究打下了基础。
