| 摘 要： | 物理化学实验教学中多用Victor Meyer法测定液态有机物相对分子质量。Victor Meyer法虽然经过多次改进应用于学生实验教学,但由于方法中的细节问题探讨不够,导致实验误差大于5%。针对产生误差的相关因素进行改进,获得实验误差小于2%的实验方法,并应用于学生实验教学中,取得满意的教学效果。

| Abstract: | Victor Meyer method was often used for the determination of liquid organic molecular weight of physical chemistry experiment teaching. However, the experimental error is always greater than 5%. According to the related factors that caused the error, we improved it to a error level less than 2%. It has been applied to the experimental teaching practice to obtain a satisfactory teaching effect. |
