| Abstract: | The quantity and characteristic of chaotic attractors in rigid-body attitude dynamical system is researched and the attribute of five equilibria is analyzed.The state trajectory of system near each equilibria is constringency along some direction,or is emanative along another direction.These state trajectories come into being periodic attractors or chaotic attractors with single-core,or two-core,or three-core,or fore-core.There are innumerable chaotic attractors in this system. |

| Keywords: | chaos chaotic attractor mechanism of chaos rigid-body attitude dynamical system |
