　　报告摘要：2 dimensional QCD is simple but nontrivial, and it is an ideal laboratory to test common ideas in QCD. In this talk, I will give a short review on 2 dimensional QCD in large N limit, then introduce 't hooft's 2 dimensional model for mesons in two different gauges. At last, I will show some results of our recent work, which support the claim of Bars and Green on the equivalence of two different approaches.
