主要对耐腐蚀聚合药物基体上药物的整个释放过程进行解析和数值研究.数学模型为基于Fick第二法则的边值问题,分为状态Ⅰ和Ⅱ.状态Ⅰ为具有移动性扩散波头的Stefan问题,而当此扩散波头消失时,即开始状态Ⅱ.该研究工作可作为数值研究更加复杂系统的基础之一.
The whole release process of the drug on the anticorrosive polymeric drug matrix is mainly analyzed and numerically studied.The mathematical model is a boundary value problem based on Fick’s second law and is divided into states I and II.Status I is Stefan Problem, and when this wave of waves disappears, it begins state II. This work can be used as one of the foundations for the numerical study of more complex systems.
