In this paper we consider the singularly pertubed autonomous syetem(1.1) dx/dt=f(x.y. ε), εdy/dt= g(x, y. e) and its degenerate system (1. 2)dy/dt=f(x.y.0), O= g(x, y,0). Suppose that system(1.2)has nonconstant almost periodic (a. p. ) solution (1.3) x =u(t), y = v(t). If the first variation equations of (1.2)with respect to (1.3 ) kas exactly one zero cliaracteristic exponent in a broad sense. we prove that for under suitable conditions. sufficiently small, system (1.1) has a unique a.p. solution x = x (t,ε), y =y(t,ε). and that for all t, as ε→0, it has||x(t, ε) -u(t)||+ ||y(t, ε) - v(t)||→0. In the proof of our result, we generalize the normal transformations, establish the exponential dichotomies, and then convert our ptoble into the corresponding problem in nonautonomus system. and hence we can solve our problem by making use of the result ascribed to K. W. Chang[5].
