摘要：
By using some differential inequality, a second-order delay differential equation(r(t)x’(t))’+p(t)x(q(t)) = 0has been investigated and some necessary condition for this equation has a nonoscillatory solution and some sufficient condition which ensures that all of the solutions of the above equation are oscillatory are obtained.
