Overreliance on Orthographic Similarity in L2‐Japanese Conceptual Processing by L1‐Chinese Learners
International Journal of Applied Linguistics, Volume 36, Issue 2, Page 1807-1820, May 2026.ABSTRACT Orthographic and phonological similarities between first (L1) and second (L2) languages can facilitate L2 processing. Particularly, L1‐Chinese learners of L2‐Japanese can benefit from the shared morphosyllabic Chinese characters (Japanese kanji/Chinese hanzi) because of their similar orthographies.

Dianci bileiqi, 2017 为了解决架空输电线路的雷击问题,研制了一种对建弧率有强烈抑制效果的爆炸强气流灭弧防雷间隙装置,使雷电流通过闪络路径流入大地,同时喷射出大量高压、高速电负性气体迅速熄灭工频续流电弧。建立了爆炸强气流耦合工频电弧的数学模型,运用有限元分析软件AUTODYN分别对爆炸气流场和耦合气流场进行仿真。进行了爆炸强气流截断工频续流电弧试验,并借助摄像机和示波器模拟记录输电线路雷击时灭弧防雷间隙中工频续流电弧的发展变化情况。试验结果表明,爆炸强气流灭弧防雷间隙能在0.4 ms内完全熄灭电弧并抑制重燃。

HIERARCHICAL PRECARITY: Dance Hosting, Labor Struggles, and Masculine Insecurities in China
Cultural Anthropology, Volume 41, Issue 2, Page 376-401, May 2026.ABSTRACT Young Chinese male migrant workers partner with middle‐aged women in dance halls, and sell intimacy and romantic relationships in everyday locations as “dance hosts.” Dance hosts experience considerable job precarity and masculine insecurities.

Cultural Anthropology, Volume 41, Issue 2, Page 402-427, May 2026.ABSTRACT This article examines how middle‐aged Chinese farmers navigate their position between a highly mobile new urban elite and the traditionally immobile elderly peasantry through a set of practices I term inter‐mobility. Based on ethnographic research in Huanglu village, I explore how their adoption of new greenhouse technologies is shaped by both

Gongye shui chuli, 2007 以供气式气液双喷嘴射流器为研究对象,采用不稳定状态下的清水充氧性能试验,考察了射流水量(Q水)、气量(Q气)、射流器喷嘴口径(D)和安装高度(H)等因素对其性能的影响,得出了影响该射流器工作性能的主次因素顺序为:H→Q水→D→Q气。在较佳工作条件下(即射流器安装高度为5m、喷嘴直径为25mm、气水比为1.4),理论动力效率可达3.23kg/(kW·h)。
