Abstract: In the teaching process of physical chemistry, the linear relationship of formula deduction should be emphasized, which can bring great convenience to the teaching of physical chemistry and the memory of physical chemistry formula. In view of the linearization formulas commonly used in physical chemistry textbooks, some conscious exploration and practice should be made in teaching ideas, teaching contents and teaching methods combine with scientific research. Through the teaching methods above, students' interest in learning is stimulated; meanwhile, their divergent thinking ability and innovative ability are cultivated.
