摘要
本实验通过拟合不同类型乙醇—环己烷质量分数—折射率曲线,利用拟合曲线绘制乙醇—环己烷双液系气—液平衡相图,分析不同类型拟合曲线对绘制平衡相图的影响。结果表明一次方程拟合的工作曲线处理数据简单方便且结果理想,建议学生实验采用一次方程拟合。
Drawing the gas-liquid equilibrium phase diagram by two types fitting curve, and the effect were analyzed. The results were showed that using the simple equation to process data was simpleness and convenience, and suggested student process data by simple equation.
