Within systematic study of hadron production in nuclear
collisions at the CERN SPS, the NA49 experiment registred
data on C+C and Si+Si interactions at 40 and 158AGeV.
The production of charged kaons in these reactions is
a subject of this presentation.
The kaons were analysed and identified with the mean
enegy loss dE/dx in the detector gas of the TPC’s.
Fully corrected transverse mass and rapidity spectera
of K+ and K− meson will be shown.
The energy and system size dependence of kaon multiplicity
and the K to Pi relatins will be presented and discused.
