Thermo-lumin.scen.e （TL） is a.kin. of lumin.scen.e deca. mea.ured with va.yin. tempera.ure. In.the process of TL the deca. pa.a.eter itself in.olves the tempera.ure effect of tra.s. Thus the tra. depth is in.epa.a.le from the deca. pa.a.eter. There a.e two sepa.a.e pea.s in.the TL curve of Zn.：Cu,Co if the mea.uremen. sta.ts from liquid n.trogen.tempera.ure. In.the experimen. we sta.ted from zero Celsius tempera.ure to isola.e the deeper tra.s. We ha.e proposed a.d rea.ized three methods for simulta.eous determin.0}ion.of tra. depth a.d deca. pa.a.eter ba.ed on.the qua.i-equilibrium model a.d experimen.a. da.a. If we trea. the ca.e of kin.tic order a.= 1 a. a.= 2, the error might be a. la.ge a. 100%.
