摘要
数据处理能力是分析问题、解决问题的基础。该文具体讨论《粘度法测定高聚物分子量》实验数据处理方法。通过采用线性拟合与采用非线性拟合的理论分析比较,以及与误差理论简单分析比较,可以断定采用线性拟合方法处理《物理化学实验》数据有直观、准确等特点,能更好地解释实验数据规律,能够提高学生数据处理能力和分析问题的能力。
Data processing ability is the base of analysis and resolving problems. The non-Linear curve fitting for experiment data of viscosity measurements to calculate relative molecular weight is compared with linear curve fitting method in this paper. The calculated result and simple error analysis results indicate that the non-linear curve fitting for handling Physical Chemistry Experiments data has the characters of perceptual intuition and precision, the non-Linear curve fitting result can explain the experiment phenomena better, and the data processing method can improve the undergraduates＇ abilities of analysis and problem-solving.
