  Inclusive spectra of the kaons produced in $Ar Sc$ collisions as functions of
their transverse momentum $p_T$ at mid-rapidity have been calculated within the
approach based on the assumption of the similarity of inclusive spectra of the
hadrons produced in nucleus-nucleus collisions at their small transverse
momenta in the mid-rapidity region taking into account the quark-gluon dynamics
in nucleon-nucleon interactions. This article gives a satisfactory description
of NA61/SHINE data on $p_T$-spectra of the $K^\pm$ mesons produced in $ArSc$
collisions at the mid-rapdity ($y\simeq$ 0).
