摘要：

We present new oscillation criteria for the second order nonlinear damped delay dynamic equation (r(t) (chi(Delta) (t))(gamma))(Delta) + p(t) (chi(Delta sigma) (t))(gamma) + q(t)f (chi(tau(t))) = 0. Our results generalize and improve some known results for oscillation of second order nonlinear delay dynamic equation. Our results are illustrated with examples. (C) 2008 Elsevier Inc.
