Abstract：
In this paper,the irreducible representations and Wigner coefficients of SL _q(3) have been obtained.The generators of SL _q(3) satisfying the serre relations are considered as 1/2 rank tensor——like of SL _q(2).Their reduced matrix elements can be calculated by a set of recurrent formula.The isoscalar factors (ISF) of SL _q(3) can also be derived by them.This means that the Racah Factorization Lemma is also exact for the quantum algebra SL _q(3).
