Transformation ratio has been derived in the case of wakefield excitation in dielectric resonator accelerator by sequence of electron bunches, the charge of which is shaped according to linear law, so that in every bunch (except the first one) the charge is distributed according to the rectangular trapezoid. At the use of certain bunch-precursor before the sequence the wakefield in the areas of localization of bunches-drivers does not depend on the longitudinal coordinate. For the increase of number of accelerated electrons the long asymptotics of sequence of electron bunches has been derived. In this asymptotic infinite sequence the short trains of drivers-rectangular trapezoids are interchanged by accelerated "high-current" bunches. This asymptotic infinite sequence provides the large transformation ratio and homogeneous decelerating wakefield, which results in the complete deceleration of bunchesdrivers. Connection of transformation ratio with the reduction rate of the wakefield after witness and connection of the transformation ratio with the witness charge and driver charge in this asymptotic sequence have been derived.
