摘要
作为充实医学物理学教学的一个重要尝试,我们将非线性动力学中的可激发系统引入教学当中,用来描述神经元、心肌细胞等的性质和行为。本文从医学物理学教学的角度,从离子通道、离子电流、膜电位等基本概念入手,对于可激发系统模型的建立及其基本性质分析做了简单介绍。将这一部分内容引入医学物理学的教学,不仅可以让学生了解物理学在医学研究中的重要价值,增强学生学习医学物理课程的兴趣和主动性,而且可以让学生初步了解神经元、心肌细胞等的生理学知识,以及模型分析中所涉及的非线性动力学的基本方法。
As an important sample to enrich the contents of medical physics, excitable system in nonlinear dynamics is inducted, and used to character the properties and behavior of neuron and cardiac cell. Beginning with the conceptions of ion channel, ion current, membrane potential, etc, this article introduce briefly from the point of medical physics, how to set up a model of excitable systems, and what its prime property is. It can help the students realize the value of physics in medical research, and enhance their interest and initiative in learning medical physics. At the same time, it can help the students understand the physiological knowledge of cells, and the technique of nonlinear dynamics referred in model analysis.
