本文在实验基础上,对药物和血浆蛋白结合的数学模型进行了探讨。提出一种新的血药结合模型,并用系统辨识方法估计出相应非线性系统的参数,本工作对这类非线性系统的辨识工作提供了有益的经验,并对深入理解药物和血浆蛋白结合的作用机制有一定意义。 In this paper, based on the experiment, the mathematical model of drug-plasma protein binding was discussed. A new model of plasma-drug combination was proposed and the system identification method was used to estimate the parameters of the corresponding nonlinear system. This work provided some useful experience for the identification of such nonlinear systems, Mechanism of action has some significance.
