The motion of the relativistic Dirac-Weyl quasi-electrons is considered in the system that is the double-barrier tunnelingresonant structure with the symmetrical rectangular Fermi velocity barriers. The rates of the transmission of the quasielectrons in this structure is calculated within a continuum model by the transfer matrix method. Focus is made on the analysis of the dependence of the quantum transparency of this system on its geometrical parameters: the barrier thickness d and the width of the quantum well w. It is shown in particular that the transmission rate strongly depends on these quantities and this allows to regulate flexibly the energy specter of the systemwhich is considered.
