With the technique of dispersion relation one-boson-exchange models involving π, ρ, ω, ηV, f and σ(0+, I=0, 416 MeV) are studied for the nucleon-nucleon interaction below 3 GeV. The models give qualitatively good fits to all observables of proton-proton scattering at 670, 970 and 1400 MeV, in addition to nucleon-nucleon elastic data. Effects of absorption on phase shifts, nucleon-meson form factor and high-energy cutoff of the one-boson-exchange amplitudes are discussed. Nucleon-nucleon scattering amplitudes in which a meson with an arbitrary spin is exchanged are formulated.
