【Abstract】 In this paper the convergence order of the interpolation oprator by almost-Hermite-Fejer polynomials Fn(f,x) are considersd. We have proved the following results. The convergence order is given bywhen using interpolation Fn(f,x) to approximate f(x) ∈C1 [-1,1] on [-1,1]. The convergence order (*) can not be further improved for a kind of special function Ha".
