The model was established among samples containing the same active ingredient from five different companies, and the model determination coefficient R2 and RMSECV （root mean square error of cross validation） were 0.9997 and 0.0223, respectively, the relative error between predicted value and chemical value of the testing set samples was between -2.71% and 3.36%, which indicated that the method to determinate the effective ingredient content in pesticide EC by the established universal model can meet the need of pesticide market monitoring.展开更多
本研究聚焦于大语言模型嵌入英语口语教学场域的人机协同模式(Effective Collaboration New Mode,简称EC-NM模式),旨在探索新技术赋能下英语口语教学的创新路径。研究运用文献研究、理论分析、案例剖析与实验验证等方法,梳理大语言模型...本研究聚焦于大语言模型嵌入英语口语教学场域的人机协同模式(Effective Collaboration New Mode,简称EC-NM模式),旨在探索新技术赋能下英语口语教学的创新路径。研究运用文献研究、理论分析、案例剖析与实验验证等方法,梳理大语言模型的发展脉络及其在英语口语教育领域的应用场景,并构建EC-NM教学模式。通过对照实验,进行多维度的数据收集与分析,评估该模式在提升学生英语口语能力方面的有效性。研究成果为英语口语教学改革提供了新思路与方法,同时拓展了大语言模型在不同教学场景下的应用研究方向。展开更多
