摘要：
In this paper we analyze discrete torsion in perturbative heterotic string theory. In previous work we have given a purely mathematical explanation of discrete torsion as the choice of orbifold group action on a B field, in the case that dH=0; in this paper we perform the analogous calculations in heterotic strings where dHnot equal0.
