对于因子对 A ⊃ B 的自同构，我们引入了强外部性的概念，并找到了保证这一点的条件。对于群G的强外作用α，得到包含体A[式G⊃A[式G]和A[式G⊃B]的主图和对偶主图。
For automorphisms of pairs A ⊃ B of factors, we introduce the notion of strong outerness and find conditions guaranteeing this. For a strongly outer action α of a group G, the principal graph and the dual principal graph of the inclusions A[formula]G ⊃ A[formula]G and A[formula]G ⊃ B are obtained.
