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。Ppfc working principle, circular current and effects of clamping capacitor are studied in this paper in detail. because of the clamping capacitor, ppfc have some good features compared with ppc : reducing the fluctuate of the input current ; restraining the voltage spike of the power mosfet ; avoiding the bias - magnetic of the transformer
由於箝位電容的加入，相對于推挽電路而言，該拓撲具備了一些獨特的優點：減小了輸入電流的脈動：削弱了開關管的關斷電壓尖峰；有效抑制了變壓器的偏磁。Chapter 2 of this paper, by using a new method of proof, we obtain the weak ergodic convergence theorem for general semigroups of asymptotically nonexpansive type semigroups in reflexive banach space. by theorem 2. 1 of chapter 1 we get the weak ergodic convergence theorem of almost orbit for general semigroups of asymptotically nonexpansive type semigroups in reflexive banach space. by this method of proof, we give the weak ergodic convergence theorems for right reversible semigroups. by theorem 2. 1 of chapter l, we generalize the result to almost orbit case. so we can remove a key supposition that almost orbit is almost asymptotically isometric. it includes all commutative semigroups cases. baillon [ 8 ], hirano and takahashi [ 9 ] gave nonlinear retraction theorems for nonexpansive semigroups. recently mizoguchi and takahashi [ 10 ] proved a nonlinear ergodic retraction theorem for lipschitzian semigroups. hirano and kido and takahashi [ 11 ], hirano [ 12 ] gave nonlinear retraction theorems for nonexpansive mappings in uniformly convex banach spaces with frechet differentiable norm. in 1997, li and ma [ 16 ] proved the ergodic retraction theorem for general semitopological semigroups in hilbert space without the conditions that the domain is closed and convex, which greatly extended the fields of applications of ergodic theory. chapter 2 of this paper, we obtain the ergodic retraction theorem for general semigroups and almost orbits of asymptotically nonexpansive type semigroups in reflexive banach spaces. and we give the ergodic retraction theorem for almost orbits of right reversible semitopological semigroups
近年來， bruck [ 5 ] ， reich [ 6 ] ， oka [ 7 ]等在具frechet可微范數的一致凸banach空間中給出了非擴張及漸近非擴張映射及半群的遍歷收斂定理。 li和ma [ 13 ]在具frechet可微范數的自反banach空間中給出了一般交換漸近非擴張型拓撲半群的遍歷收斂定理，這是一個重大突破。本文第二章用一種新的證明方法在自反banach空間中，研究了揚州大學碩士學位論文2一般半群上的（ r ）類漸近非擴張型半群的弱遍歷收斂定理，即:定理3 . 1設x是具性質（ f ）的實自反banach空間， c是x的非空有界閉凸子集， g為含單位元的一般半群， s =仕工， 。These achievements will enrich the relationship between pair - network and network, and further understand the internal connection between hereditarily closure - preserving families and point countable families or locally finite families, and better certain topological non - variability of the space with pair - networks, and enrich the theory of generalized metric space. this paper reached some principal conclusions about the space with - hereditarily closure - preserving pair - networks
