摘要:

为了满足当今教学的信息化发展趋势,本研究基于随机扩散理论建立了气相色谱仿真模型并开发了相关的计算模拟软件Stochastic Diffusion-Chroma。以混合组分分别在气相色谱填充柱和毛细管柱中的扩散分离模拟为例,探究了随机扩散理论模型在色谱理论教学和实验教学方面的应用。基于随机扩散理论的仿真教学改变了传统的教学模式,将学生较难理解的抽象色谱动力学基本理论转变为动态的具体形象,激发了学生的学习兴趣,提高教学质量。

Abstract:

In order to keep up with the trend of informationization in teaching, a gas chromatographic simulation model based on the stochastic diffusion theory was established and the corresponding computer simulation software Stochastic Diffusion-Chroma was developed in this study. The simulations of diffusion and separation of mixed particles in both packed column and capillary column were presented. The application of stochastic diffusion theory in chromatography theoretical teaching and experimental teaching were explored. The simulation teaching based on stochastic diffusion theory changes the traditional teaching mode. It transforms the abstruse chromatographic dynamics into dynamic and intuitive description, stimulating students' interest in learning and improving teaching quality.
