<正> Let f∈Lpr(R),1p—metricesis given in[1].From embedding Theorem and Stein inequality,it follows,that if f∈Lpr(R),1qr(R),1(k)∈Lp(R)∩Lq(R),k=0,1,…,r-1.In this paper,we con-tinued Fang's work in[1],and obtain the bound for aliasing error of function f∈Lpr(R),1q-metrices(p≤q≤∞).And the order is exact when 1<p≤q≤2.
