摘要
讨论了具有强迫项的Ｌｉｅｎａｒｄ方程解的有界性，得到了此方程的所有解及其导数有界的充要条件．所获结果改进和推广了Ｓｕｇｉｅ Ｊ（１９８７）和杨启贵（１９９９）的文章中的相应结果．
In this paper, the boundedness of solutions of the forced Lienard equation is studied. A new sufficient condition, as well as, a new necessary and sufficient condition for all solutions and derivatives of (E) to be bounded are given. Our results improve and generalize the corresponding results in Sugie J.(1987) and Yang Qigui(1999).
