Abstract In the various models, we study the influences of the softness of nuclear matter, the vacuum fluctuation of nucleons and σ mesons on the production of strange particles in neutron stars. We find that the stiffer the nuclear matter is, the more easily the strange particles is produced in neutron stars. The vacuum fluctuation of nucleons has large effect on strange particle production while the one of σ meson has little effect on it.
