摘要
在单模激光的Lorenz混沌行为在第二阈值处存在“准不变量V”的基础上,用理论分析与数值实验的方法,得出即使不在第二阈值处,同样存在“准不变量V”,且可用来判断系统何时进入混沌状态.
Theoretical analysis and numerical experimentation are carried out based on the existence of quasi invariant V at the second threshold for single mode laser＇s chaotic behavior of a Lorenz＇ s system. It is concluded that the quasi invariant V does exist, and is not restricted to the second threshold. This can be used to judge when the system enters a chaotic state.
