摘要: 考虑在高速机构中有着广泛应用的二阶泛函微分方程
(r(t)x'(t))'+a(t)xa(t-τ(t))=f(t).(A)
其中0 < a < 1,是两个奇数之比.文中给出了保证方程(A)的一切振动解渐近趋于零的若干充分条件.

Abstract: In this paper we consider the functional differential equations of second order
(r(t)x'(t))'+a(t)xa(t-τ(t))=f(t) (A)
where 0 < α < 1 and α is a ratio of odd integers. The equations have extensive applications to high speed mechanisms. Several sufficient conditions have been found to ensure that all oscillatory solutions of (A) approach zero asymptotically.

Key words: high speed mechanism, functional differential equations, oscillation solutions
