The authors discuss the boundedness and approximation properties of translation and mean operator on H1(∑) by the estimates of high degree difference on ultraspherical polynomials, atom de-composition and construct properties on sphere. Also the boundedness and approximation of linear means at all kinds of indexes on Hp(0 < p < 1) and the almost everywhere convergence of Cesaro means are established.
