In this paper we study the method of interpolation by radial basis functions in H~k(k ≥ 1) and give some error estimates. By means of such interpolation with a special kind of radial basis function, we construct a basis in H~k(k ≥ 1). Combined with the Galerkin method, this theory can be applied to solve boundary value problems for elliptic partial differential equations (such as the third boundary value problem for Poisson equation and the corresponding problem for the biharmonic equation), and some numerical experiments are also given.

Experiments on decalcification and activation of osteoinductive ability, comparison between the osteogenesis of demineralized bone matrix in orthotopic and in heterotopic sites, and correlation between immune response to allograft of bone and osteoinductive activity of the graft, were reported in this paper. 1. Syngeneic deminerolized bone matrix and the mixture of DBM with bone ash or acid-soluble protein extracted from demineralization was implanted into muscle pouch of mice, subsequently, the inhibition of DBM osteoinduction by bone ash or acid-soluble protein was demonstrated with histological and by means of alkaline phosphatase assay.
