In this paper,we study the generalized Riesz transform?L-1/2associated with divergence form elliptic operator and its commutator[b,?L-1/2]generated by generalized Riesz transform and BMO(Rn)functions.By them ethods of studying ring decom position of function and thier corresponding truncated operators, their boundedness of the results form space MKα,λp1,q(Rn)to space MKα,λp2,q(?n)were established.The well-known results gotten by before scholars are extended.
