Abstract: The Boltzmann approximation of the phase-space distribution functions of quarks and of pious, previously adopted by the authors,is generalized to a complete expression.After calculating the density of particles from the temperature of the central rapidity region,the dilepton production in Bjorken's(1+1)dimensional scaling expansion system is studied.We find that the generalized approximation distribution function significantly changes the characteristic dilepton distribution for the prediction of the quark matter formation.
