讨论了影响气化法测定四氯化碳分子量实验误差的因素，对文献[1]中报道的方法进行了改进．学生按改进的方法进行实验，测定的四氯化碳分子量在150～155范围内．
The factors influencing the experimental error of gasification method for the determination of molecular weight of carbon tetrachloride were discussed. The method reported in [1] was improved. Students conducted experiments in an improved way, measuring CCl 4 molecular weights in the 150-155 range.
