Bifurcation of Homoclinic Orbit in Fast Oscillation
快变振荡下的同宿轨道分支

This paper considers homoclinic bifurcation of the system s with angular variable in fast oscillation. By establishing the whole Poincar é map,the authors discuss the persistence of homoclinic orbits and the existe nce of periodic orbit bifurcated from it. Some known results are extended
