摘要：
For loop integrals, reduction is the standard method. Having an efficient way to find reduction coefficients is an important topic in scattering amplitudes. In this paper, we present the generation functions of reduction coefficients for general one-loop integrals with an arbitrary tensor rank in their numerator.
