A Glauber multiple scattering theory in terms of partons and nucleons is applied to study productions of kaon, lambda and antilambda in 50 GeV proton-nuclcus scatterings at JHF (the Japan Hadron Facility). The ratios of the differential cross sections of nucleon-tungsten to nucleon-beryllium are calculated versus the transverse momentum at central rapidity. The cancellation between the single and double scattering amplitudes leads to nuclear enhancement of strangeness production at central rapidity.
