Different from the basic chemistry experiment course in the lower grades of the university, the higher grades offer self-designed experiments, focusing on independent thinking and active exploration. Taking the "determination of N content in TiCN-based alloys" as an example, this paper introduces the whole process of self-designed experiments, including the digestion of solid samples, the extraction of substances to be measured, analysis and testing, data processing and evaluation, and introduces theoretical knowledge into practical problems, and uses experimental methods to deeply integrate the two, improving students' ability to judge, solve problems and comprehensive quality.
