BOUNDEDNESS OF SOLUTION AND GLOBAL ASYMPTOTIC BEHMIOR OF LIENARD EQUATION
Lié nard 方程解的有界性与整体渐近性

In this paper, the boundedness of solution and the global asymptotic behavior of Lienard equation x f(x) x g(x) = e(t), where e(t) is absolutely integrable, is studied. Necessary and sufficient conditions for all solutions to be bounded and for all solution to have their derivatives convergeing to zero are given.
