J-J型方程中的扭结现象

PHENOMENON OF KINKS IN THE SYSTEM OF J-J TYPE

本文通过对J—J型方程解的轨道、poincar(?)截面、功率谱及Lyapunov指数等诸方面特征的计算和分析,研究了J-J方程中的扭结现象。

By Studying and calculating poincare section . power spectrum and Lyapunov exponents about the system of J -J type , we have obtained : (1)When some parameters vary and the rotating number is fixed , there is the route of quasi-period to chaos, which embodies that the fixed circle produces kinks at first , and with Jerking - lengthening and compression of kinks , then develops into station of chaos .(2 )There is only outer-kinks in the single system of J -J type ,and there are two kinks .inter-kinks and outer-kinks in the double system of J-J type .
