In his notes, Dr. Hasselmann pro-posed to combine correlation analysis and linear regression analysis in climate prediction re-search. The main idea is to decompose the physical field into its principal oscillation patterns.展开更多

Many courses are taught in large classes with several classes together. It is difficult for teachers to make a fair quantitative evaluation of students achievements in normal times. The assessment of normal performance is a major pain point of large-class teaching in Chinas universities and a major difficulty in teaching research. The purpose of this research is to study the fairness, rationality and effectiveness of the normal performance evaluation of large-class college physics courses by using "Chaoxing Xuexitong", and to provide a reference case for optimizing the normal performance evaluation scheme of large-class courses in China.展开更多
