摘要
结合生理学内分泌调节理论,采用了变步长龙格-库塔法,以Matlab软件为计算平台,对改进的下丘脑-垂体-肾上腺轴激素脉冲分泌的非线性动力学进行了参变量数据模拟,求出了下丘脑-垂体-肾上腺轴激素脉冲分泌的周期振荡解及混沌解.结果显示,此分泌系统中激素浓度变化与实验事实相符,其混沌模型是合理的.
In this paper,the periodic oscillation and the chaos solution of an improved model for the hormone secretion of the hypothalamus-pituitary-adrenal axis was proposed.This model is based on Physiology endocrine regulation theory and used Matlab working platform and the four order Runge-Kutta（RK4） method to simulate a group of parameter data which fit the model.The results showed that the all changes with time of the concentrations of the hormones in the model agree well with experimental results.From the results,the model is a more reasonable one.
