摘　　要：举例展示了将编程语言R用于分析化学的教学。运用R的数值计算功能,求解化学平衡中涉及的高次方程,不仅免去繁琐的判别与公式简化过程,还将所有化学平衡计算统一为同一种方法。运用R的绘图功能,绘制分布分数曲线、滴定曲线等。运用R的统计分析功能,替代传统的人工计算和查表方法。运用R的数值模拟功能,帮助学习者理解误差传递、置信区间等复杂概念。与当前分析化学教学中普遍采用的Excel相比,R还具有操作过程代码化、自释性高、扩展性强、安装使用方便等特色。在分析化学教学中应用R不仅有利于改善分析化学的学习效果,也为学习者掌握R这一有力的科研工具提供契机。Application of programming language R for the teaching of analytical chemistry was demonstrated with several examples.Numerical calculation of R was used to solve the high-order equations involved in chemical equilibrium.It avoided the cumbersome processes of formula simplification,and also unified all equilibrium calculations into the same method.Plotting functions of R were used to plot species distribution curves,titration curves,etc.Statistical analysis functions of R were used to replace the traditional manual method.Numerical simulation functions of R were used to help students understand complex concepts such as propagation of error and confidence interval.Compared with Excel,which is commonly used in the teaching of analytical chemistry,R also has the characteristics of being code-based,self-explanatory,flexible,rapidly evolving,and readily accessible.The application of R in teaching of analytical chemistry not only helps to improve the learning efficacy,but also provides an opportunity for students to master the powerful research tool R.
