摘要：
The theoretical analysis for the threshold pion production has been performed by using the models of heavy-meson exchange and pion-rescattering including the effect of nucleon resonances. The experimental data of the pi (-) production support the relative sign between the s-wave and p-wave pion-production amplitudes which is given by these models. The d-wave pion production amplitude is discussed about the angular distribution of pi (0) production. The spin correlation observables give information about the partial wave amplitudes.
