摘　　要：In this paper, we obtain a properly posed set of nodes for interpolation on a sphere. Moreover it is applied to construct properly posed set of nodes for Lagrange interpolation on the trivariate polynomial space of total degree n.In this paper, we obtain a properly posed set of nodes for interpolation on a sphere.
