摘　　要：研究一类带有非线性耗散项及源项的非线性Petrovsky方程的初边值问题。在非线性耗散项和源项较弱的假设条件下,证明了该问题整体解的渐近性态。The initial-boundary value problem for some nonlinear Petrovsky equation with nonlinear dissipative term and source term is studied. Under weaker assumptions about nonlinear dissipative term and source term, the asymptotic behavior of global solution to this problem is proved.

关 键 词：非线性Petrovsky方程 非线性耗散项和源项 初边值问题 渐近性态
