摘要：

Some new sufficient conditions are established for the oscillation of fourth order neutral differential equations with continuously distributed delay of the form (r(t)N-x '''(t)(alpha))' + integral(b)(a)q(t, v) x(beta) (delta(t, v)dv = 0, where t >= t(0) and N-x(t) := x(t) + p(t)x(phi(t)). An example is provided to show the importance of these results.
