摘要
研究了一个受白噪声干扰的随机化学3变量自催化剂反应模型的动力学行为.证明了随机系统的解是正的且全局存在的,并在白噪声强度值满足一定的条件下,得出随机自催化剂反应系统具有遍历性且是平稳分布的.
A stochastic three-variable autocatalator chemical reaction model disturbed by white noise is introduced.It is proved that the solution of the stochastic system is positive and global.Furthermore,it is shown that there is a stationary distribution for the stochastic autocatalator reaction system and it has ergodic property with some conditions about the values of white noise.
