Abstract
The paper is devoted to the calculation of additional two-loop O(\alpha_s^2) MSSM corrections to the relation between the pole mass of the t-quark and its running mass in the DR scheme. The value of the second order contribution from large mass expansion is studied. As a by-product we calcutated two-loop anomalous dimension of the running quark DR-mass in the supersymmetric QCD.
