研究了满足一定条件的两个顶点算子代数张量积的单电流扩张。我们建立了简单电流扩张的融合规则和张量因子的融合规则之间的关系。在一种特殊情况下，我们构造了一个简单的电流扩张链。我们还讨论了一些简单电流扩张的不可约扭模。
We study simple current extensions of tensor products of two vertex operator algebras satisfying certain conditions. We establish the relationship between the fusion rule for the simple current extension and the fusion rule for a tensor factor. In a special case, we construct a chain of simple current extensions. We discuss certain irreducible twisted modules for the simple current extension as well.
