本文分析了由一个已知的共形场论通过有限对称群模化得到的（轨道）共形场论的手征性质。针对一类轨道折叠，通过研究单圈特征的模变换性质，推导出融合规则。结果表明，与明确的计算环形和c =1模型。
We analyze the chiral properties of (orbifold) conformal field theories which are obtained from a given conformal field theory by modding out by a finite symmetry group. For a class of orbifolds, we derive the fusion rules by studying the modular transformation properties of the one-loop characters. The results are illustrated with explicit calculations of toroidal andc=1 models.
