In the paper we are continued investigations on a generalization and a improvement of the R. T. Turganaliev's result by the deduction of the asymptotic formula for the mean-value of the Rieman's zeta-function in the critical stripe with the rest term, having the power in the reduction. We are found the asymptotics of Dirichlet's $L$-function in the critical stripe, which improves the R. T. Turganaliev's theorem on the zeta-function for all values of the real part ($1/2\mathrm{Re}\, s\leq 1$). This result are got for the account of the different using of estimations of trigonometric sums on the base of the second derivative in the exponent.
Keywords: Dirichlet's characters, Dirichlet's functions, the zeta-sum twisted together with the Dirichlet's character.
