借助于N -连续性概念，得到了连续和几乎连续序同态的一些特征。
From the concepts of N-continuity, we obtain some conclusion on continuous and almost continuous order-homomorphism.
在此基础上，最后引入并研究了几乎连续、几乎开和几乎闭序同态。
Bascd on this, al - most continuous, almost open and closed order-homomorphisms are intro - duced and studied.
最后引进强准连续、强准开(闭)序同态，讨论它们的性质。
Finally, strong pre-continuity and strongly pre-open (closed) mappings are introduced and their properties are discussed.
