Learning Styles, Engagement and Anxiety in AI‐Mediated Writing: A Multimodal Feedback Study
ABSTRACT Artificial intelligence (AI) tools now permeate English academic writing. However, evidence on how feedback modalities align with student differences and with psychological mechanisms remains limited. Prior work often reduced learning styles to simple matches with delivery modes and treated learning engagement and writing anxiety as peripheral.

小型模块化熔盐堆具有广泛的发展前景,但由于受到空间尺寸、传热效率和高温工作环境的限制,对熔盐换热器的性能提出了较高的要求。因此对不同微通道换热结构在高温环境下的流动换热特性的研究具有重要意义。本研究采用数值模拟方法,以熔盐(FNaBe)-超临界二氧化碳(SCO2)换热器为研究对象,在FNaBe熔盐侧分别采用Z型和波浪型等两种板翅式通道结构,在SCO2侧分别采用椭圆翅片和翼型翅片两种通道结构,对4种通道结构的整体和局部流动传热特性进行了研究分析。研究结果表明:熔盐侧Z型流道具有更强的传热性能 ...
