摘　　要：总结归纳化学专业学生对色谱理论难点与重点理解方面突出存在的问题,结合苯并(b)荧蒽与苯并(k)荧蒽的两种色谱以及与质谱联用的三种分析方式,与21种有机氯农药在分析过程中出现色谱峰漂移现象进行故障溯源与原因分析。采用教研结合的教学方式讲解存在问题,打破传统单一枯燥的讲解模式与习题巩固方式。该教学方式对提高学生理解,优化教学效率的效果显著。This paper summarizes the outstanding problems of chemistry students in understanding the difficulties and key points of chromatographic theory,combined with two chromatographic and mass spectrometric analysis methods of benzo(b)fluoranthene and benzo(k)fluoranthene,and 21 kinds of organochlorine pesticides in the analysis process of chromatographic peak drift,fault tracing and cause analysis.Using the teaching method of combining teaching and research to explain the existing problems,breaking the traditional single and boring explanation mode and exercise consolidation mode.This teaching method has a significant effect on improving students’understanding and optimizing teaching efficiency.
