摘要：

This article studies the oscillation of solutions to the delay differ-ential equation x & PRIME;(t) +p(t)x(& tau;(t)) = 0. We improve the existing oscillation criteria, by lowering the existing bounds on lim sup & int;& tau;t p that provide sufficient conditions for the oscillation of all solutions.
