摘要
讨论了一类具有扭结周期轨道的三阶系统 ,得到了该系统有 k系不变环面 ,在每一个系环面上存在扭结周期轨道的条件 。
A class of threedimensional systems which exist knotted periodic trajectories is discussed, the conditions about that there are k groups invariant torus and there exists knotted periodic trajectories on each group are obtained.What is more, the conclusion can help to understand the moving principle of eddy ball.
