Abstract
The thermal relaxation time for a chemically non-equilibrated gluon pl asma is calculated using the non-equilibrium Debye mass as the infrare d regulator. The dependence of the thermal relaxation time on the fuga city is given. We find that there is a threshold fugacity lambda(g). When lambda(g) < lambda(g), tau(NEQ)/tau(EQ) decreases sharply with i ncreasing fugacity, while lambda(g) > lambda(g), the ratio is almost unchanged. PACS: 24.85.+p, 12.38.Mh, 52.25.Dg.
