In this paper, we find the greatest value αand the least value β in（1/2,1）such that the double inequality M 2 （αa+（1-α）b,αb+（1-α）a）＜S（a,b）＜M 2 （βa+（1-β）b,βb+（1-β）a）holds for all a,b＞0 with a≠b,in where, ■, and M p （a,b）=[（a p +b p ）/2] 1/p denote the second Seiffert mean, and P-th power mean of two positive numbers a and b, respectively.

Let {Sj}nmj=1 be an iterated function system (IFS) of contractive similitudes on R3 defined by Sj(a)=aj+λ(a-aj),j=1,2,…,nm, where nm is the vertex number of the regular m-polyhedron in R3, aj is the vertex of the regular m-polyhedron, and 0λ1. We give a condition on λ so that IFS {Sj}nmj=1 satisfies the contact condition when λ=ρm. Also, the Hausdroff dimension of the attractor Km of {Sj}nmj=1 is given for 0λ≤ρm.

M.W.Botsko,based on the concepts of continuity and the derivative,generalized the Riemann integral and obtained a new integral-G integral.In paper[1],the authors studied the Lebesgue measurability of the Ginte- grable function.And in this paper,the author study the series of integration term by term of the G integral,the G integral of two functions' product and the mean value theory of the G integra.At the same time,the author puts forward a bounded function which is not Riemann integrable but G integrable.
