Abstract A method is introduced to calculate the UV-divergent parts at one-loop level in dimensional regularization. The method is based on the recursion, and the basic integrals are just the scaleless integrals after the recursive reduction, which involve no other momentum scales except the loop momentum itself. The method can be easily implemented in any symbolic computer language, and a implementation in Mathematica is ready to use. Title of program: UVPart Catalogue Id: AELY_v1_0 Nature of problem To get the UV-divergent part of any one-loop expression.
