Abstract: Suppose that L is a complete residuated lattice, a stratified L-topology in sense of Hohle, called the fuzzy Scott topology, is defined on Directed Complete Poset（DCPO）. Based on stratified L-filters, the corresponding Scott convergence theory is established. It is shown that a DCPO is continuous iff for any stratified L-filter, Scott convergence coincides with convergence about the fuzzy Scott topology.

摘要： 设L是一个完备剩余格，定义了定向完备偏序集上的Hohle意义下的满层L-拓扑，称之为模糊Scott拓扑；基于满层的L-滤子，建立了相应的Scott收敛理论。证明了一个定向完备偏序集是连续的当且仅当对于每一个满层的L-滤子，其Scott收敛等价于按模糊Scott拓扑收敛。
