Huang Chengbiao. On a Class of Unsymmetric Oscillators with a Parameter[J]. Acta Scientiarum Naturalium Universitatis SunYatseni, 1994,33(1):98-102.DOI:
stability and expression of the periodic solutionsfor a class of unsymmetric oscillators with a parameter are studied.The relationshipbetween the amplitudes of the periodic solutions and the parameters is given. Also thebifurcations are obtained.The first-order expressions of the periodic solutions
periodand frequency are computted emplying the generlized L-P method Comparisions with thenumerical mcthod are made.
