摘要：

We present a semi-recursive method for calculating the rational parts of one-loop gravity amplitudes which utilises axial gauge diagrams to determine the non-factorising pieces of the amplitude. This method is used to compute the amplitudes M1-loop(1(-), 2(+), 3(+), 4(+), 5(+)) and M1-loop(1(-), 2(+), 3(+), 4(+), 5(+), 6(+)).
