International Journal of Applied Linguistics, Volume 36, Issue 1, Page 522-539, February 2026.ABSTRACT This paper examines the features of metadiscourse across different teacher moves in university linguistics classroom discourse and the teaching strategies reflected in its use. The results reveal that teachers employ diverse metadiscourse during classroom interactions to support student reasoning.

Guangtongxin yanjiu, 2010 在波分复用（WDM）光网络中,文章将经过各节点的最短路径的总长度作为权值对节点进行排序,利用优先配置最短路径总长度较长的节点的思想,对已有的"子图+代数决策图（ADD）"算法进行改进,得到了一种新的"子图+路径长度排序（PLS）"算法。对两种算法进行了计算机仿真,结果显示新算法在保证结果准确的同时,较有效地降低了运算的时间复杂度。

Jianzhu Gangjiegou Jinzhan, 2022 为研究混凝土强度、含钢率等参数对方矩形钢管约束超高强混凝土短柱轴压承载力的影响，并探讨现有承载力计算方法的适用性，采用已验证的有限元模型，对方矩形钢管约束混凝土短柱轴压极限承载力进行参数分析，根据计算结果对现有承载力计算方法开展精度评估，并对承载力计算方法进行了修正。研究发现：随着混凝土强度的提高，套箍力系数相同时，约束效果趋于降低，内填超高强度混凝土构件的约束效果受含钢率、倒角率影响较小；矩形钢管约束混凝土短柱的约束效果随着长短边边长比值的增加而降低；由于混凝土强度提高，约束效果下降 ...

Shuitu Baochi Xuebao, 2022 为了解不同草带宽度对紫色土坡耕地水土流失的影响,以铺设四季青草带的紫色土坡面为研究对象,采用放水冲刷模拟试验,以裸坡为对照组,研究不同放水冲刷流量和草带宽度条件下坡面细沟形态变化和减沙减流效应。结果表明:(1)沟深随草带宽度增大呈先减小后增大趋势,而沟宽、沟长和沟宽深比均随草带宽度呈先增加后减小趋势;此外,沟宽、沟深和沟长随流量的增大而增大,而宽深比随流量的变化不明显;(2)当流量较小时(4 L/min),各坡面产流率和产沙率随着草带宽度的增大而减少,100 cm草带宽度的减流效益最高,为48.41 ...
