In the first part, the concepts of the completely normal spaces and strong completely normal spaces in l - topological spaces are defined, which are the generalization of the completely normal spaces in general topological spaces. they are some good properties such as hereditary, weakly homeomorphism invariant properties, good l - extension, but they are n ' t producible in general. moreover, their several sufficient and necessary conditions in induced spaces are presented
第一部分的主要內容如下：第一部分這一部分是將一般拓撲學的完全正規分離性的概念推廣到了l -拓撲空間，給出了l -拓撲空間的完全正規分離性和強完全正規分離性的定義並討論了它們的若干性質，比如，它們都是可遺傳的，弱同胚不變的， 「 lowen意義下好的推廣」等。 -
In the framework, a control mesh may be arbitrary one - dimensional or two - dimensional orientated topological manifold, and the curve or surface is defined on differential manifold homeomorphic to the control mesh with a potential function as its basis functions. this method is an extension of nurbs, which efficiently overcomes the limitations of nurbs
廣義有理參數曲線曲面定義在與控制網格拓撲同胚的微分流形上，以高度一般的勢函數為基函數，其控制網格可以是任意的一維拓撲流形和二維可定向拓撲流形。 -
The technique of the multi - channels sharing and the bus topological structure are adopted in the system, which does n ' t set the central switch and which not only can realize many users share a few explosion - proof channels, but also reduce the cost of the channels, while improving the utilization factor of them. the users " extension is flexible and convenient. the system has the functions of amplifying call and telephone talk
