International Journal of Applied Linguistics, EarlyView.ABSTRACT While English‐medium instruction (EMI) and English for Academic Purposes (EAP) courses are designed to promote language and content learning, their prevailing English‐only approaches often undermine students’ learning motivation. Against this backdrop, translanguaging has gained recognition as an effective pedagogical practice to support ...

The Impact of AI‐Assisted L2 Learning on Learners’ Emotions: A Meta‐Analysis
International Journal of Applied Linguistics, EarlyView.ABSTRACT The scope of research on AI‐assisted second/foreign language (L2/FL) learning has expanded beyond learning outcomes to focus on learners’ emotional experiences. Despite their proliferation, existing empirical findings are inconsistent, and few studies have systematically synthesized the impacts of AI‐assisted L2 learning on learners’ emotional

光致变色有机化合物研究 Ⅳ.含可反应基团的螺吡喃化合物的合成
四川大学学报. 自然科学版, 1993 吲哚啉苯并螺吡喃是一类重要的有机光致变色化合物。一些化合物具有很好的光致变色性质,将其作为光致变色介质与半导体材料和聚合物等载体结合形成光致变色材料已经取得实际应用。近年来,国外开始将螺吡喃分子引入聚合物链上,形成螺吡喃聚合物。我们的工作是合成在吲哚啉环上含有-CI,-OH,-CH=CH2基团的螺吡喃化合物,它们均可与相关的聚合物及单体形成高分子化合物。特别引入含CH2=CH-长链反应基团,不仅将螺吡喃分子的光致变色波长红移至可见光区,而且将其与含有Si ...

四川大学学报. 自然科学版, 2012 提出了一种新的证据预处理的冲突证据合成方法.融合系统中各证据的重要程度可能不同,直接利用公式合成可能得到与实际相悖的结论.利用明考夫斯基距离,根据系数的不同分别得到绝对距离、欧式距离和切比雪夫距离,三个距离表示有一定差异,通过融合三个距离得到证据距离,从而可以较准确表示证据的关系.利用证据距离进一步转化为表示证据权重的权值,利用权值对证据进行预处理,从而可以把冲突证据的合成问题进行转化,再通过改进的合成公式,对预处理后的证据进行合成,得到合成结果.最后通过同其它算法的算例比较 ...
