摘要
针对环境化学教学过程中遇到的复杂方程求根问题,利用MATLAB软件强大的计算功能,致力于获取大气中不同CO_(2)含量所对应的降水pH值及开放和封闭体系中CaCO_(3)在纯水中的溶解度。首先,对教材中所涉及方程的推导过程进行了优化;其次,通过MATLAB 2023b软件的fzero命令编写复杂方程求根的程序代码,使学生初步掌握MATLAB求根方法;最后,根据运行结果进行分析和讨论,使学生更好地理解和掌握。将MATLAB软件应用于环境化学教学中,不仅有助于激发学生的学习兴趣、提高教学效果,而且符合教育教学发展目标,也为推动环境化学教学改革做出积极探索。
In response to the problem of finding the roots of complex equations encountered in the process of environmental chemistry teaching,one was devoted to obtaining the precipitation pH values that corresponded to different CO_(2) contents in the atmosphere as well as the solubility of calcium carbonate(CaCO_(3))in pure water in open and closed systems through MATLAB software with the powerful calculation ability.Firstly,the derivation process of the equations involved in the textbook was optimized.Secondly,by using the fzero command of MATLAB 2023b software to write program codes for finding roots of complex equations,students could have a preliminary grasp of the MATLAB root finding method.Finally,the analysis and discussion were conducted according to the running results,so that students could better understand and master them.The application of MATLAB software in environmental chemistry teaching not only helped to stimulate students'learning interest and improve teaching effectiveness,but also conformed to the development goals of education and teaching,and made a positive exploration for promoting the reform of environmental chemistry teaching.
