摘要：

Using the integral averaging method and the generalized Riccati technique, we derive new interval oscillation criteria for second order nonlinear partial delay differential equations. These results are different from most known ones in the sense that they are based on information only on a sequence of subintervals of [0, infinity), rather than on the whole [0, infinity). Our results are of a high degree of generality and sharper than the existing results in literature.
