FURTHER INVESTIGATION ON THE S-MATRIX IN MESON THEORY
关於介子理论裡S方阵之進一步的研讨

It was shown in the preceding paper "The S-Matrix in Meson Theory" that the S matrix for certain types of meson theories can be made divergence-free by charge and mass renormnalizations if the radiation effect of the meson self-energy part has been taken into account properly. This amounts to replacing the following function occurring in integralsby the function
