The temperature and magnetic field dependences of a.c. resistance of c-axis oriented (Tl_{0.5}Pb_{0.5})(Sr_{0.8}Ba_{0.2})_2Ca _2Cu_3O_x and (Tl_{0.6}Pb_{0.24}Bi_{0.16})(Sr_{0.9}Ba_{0.1})_2Ca_2Cu_3 O_x thin films as well as of (Tl_{0.5}Pb_{0.5})(Sr_{0.8}Ba_{0.2})_2Ca_ 2Cu_3O_x bulk sample from 77 K to room temperature and in magnetic fields from zero to 3000 Oe were measured and analyzed. The magnetic field and temperature dependence of the resistive superconducting transition and irreversibility field were discussed both in the flux-creep model and in the superconducting liquid vortex state model. The temperature width of resistive transition was explained taking advantage of the Ambegaokar and Halperin model of the resistance of superconducting Josephson weak links and barrier of vortex motion presented by Tinkham. The irreversibility field was described by an exponential formula.
