摘要：

<正> Suppose that is an analytic self-map of the mit disk Δ.We consider compactuess ofthe composition operator from the Bloch space into the spaces Qk defined by a egative.nondeereasing function K（r）for 0r<.Onr compactness condition depends only on which can comsidered as a slight improvement of the known results.The compactness of from the Dirichlespace into the spaces Qk is also investigated.
