A universal function f with summed form in dual reciprocity boundary element formulation for axisymmetric problems has been derived from three dimensional Poisson's equation whose right hand is radial basis function. The singularity on symmetric axis of the function f was eliminated by integral average of function f and selecting different function f on the basis of the different characteristic of calculated zones. The feasibility of present selection and the singularity processing of function f was well proved by the calculation of the transient heat conduction problems in solid cylinder and sphere.
