摘要：
By employing a class of new functions Phi = Phi(t,s,l) and a generalized Riccati technique, some new oscillation and interval oscillation criteria are established for the second-order nonlinear differential equation (r(t)y'(t))' + Q(t,y(t),y'(t)) = 0 The obtained interval oscillation criteria can be applied to equations with forcing term. Two examples are also included to show the significance of our results. (C) 2009 Elsevier Inc. All rights reserved.
