摘要 研究了耦合极限环系统同步的振幅效应 .结果表明 ,耦合系统中振子的平均频率随耦合强度的变化过程表现为同步分岔树结构 ,而振子的平均振幅随相同步的进程却是由均匀化逐渐分岔而达到非均匀化的过程 . The effect of amplitude on synchronization in coupled limit cycles is studied. Phase synchronization among oscillators shows a tree like bifurcation and a number of clustered states are experienced. The phase synchronization bifurcation is accompanied by a bifurcation process of the amplitude of oscillators, that is, the synchronization of phases correspond to a inhomogeneous process of amplitudes.
