摘要：

In this paper, we establish some sufficient conditions for the persistence of system x '(t) = x(t) f(t, x(t)) without the condition that f (t, phi) is monotonously decreasing with respect to phi. This partly answers the open problems proposed by Teng. (C) 2008 Elsevier Ltd. All rights reserved.
