摘要：In this paper we consider the effective reducibility of the following linear differentialequation: x = (A + ∈Q(t,∈))x, |∈| ≤ ∈0, where A is a constant matrix, Q(t,e) is quasiperiodic in t, and e is a small perturbation parameter. We prove that if the eigenvalues of A and the basic frequencies of Q satisfy some non-resonant conditions, the linear differential equation can be reduced to y = (A^*(∈) + R^*(t, ∈))y, |∈| ≤ ∈o, where R^* is exponentially small in ∈.
