  Formulas for the longitudinal dielectric permeability in quantum
non-degenerate and maxwellian collisional plasma with the frequency of
collisions proportional to the module of the wave vector, in Mermin's approach,
are received. Equation of Shr\"{o}dinger - Boltzmann with integral of
collisions relaxation type in Mermin's approach is applied. It is spent
numerical and graphic comparison of the real and imaginary parts of dielectric
function of non-degenerate and maxwellian collisional quantum plasma with a
constant and a variable frequencies of collisions. It is shown, that the
longitudinal dielectric function weakly depends on a wave vector.
