Secondly, basing on the theory of on - off gain of small signal, the raman gain coefficient for frequency shift between 0. 5 and 20 thz of standard sigle mode optical fiber is measured by pump - probe method through a super luminescent diode ( sld ) as a broadband small signal probe source. thirdly, numerical simulation analysis of gain characteristic of raman fiber amplifier for c band wdm signal light is made according to the raman gain coefficient of the fiber measured before through target and four rank runge - kutta method. at the invariability of wavelength and maximum power of each of two pumps, schematic of powers of two pumps for best flatness on c band wdm optical gain was found out, at the same time, the factors of resulting in gain saturation is analyzed, too
本文首先應用經典的電磁理論對拉曼光纖放大器的工作機制進行了分析，然後，根據小信號理論推導出的開關增益求出了光纖拉曼增益系數的表達式，採用泵浦-探測波的方法，利用超輻射激光二極體（ superluminescentdiode簡稱sld ）作為探測光源，測量了所用標準單模光纖頻移為0 . 5 - 20thz的拉曼增益系數，之後根據所測得的光纖的拉曼增益系數譜對應用該類光纖構成的放大c波段wdm光信號的拉曼光纖放大器的增益特性採用打靶法和四階龍格- - -庫塔進行了數值計算，在給定了兩個泵浦光源的波長和最大功率后，找出了反向泵浦情況下使c波段wdm光源增益最平坦的兩個泵浦的各自最佳功率，同時也分析了導致信號光飽和的原因。Firstly, the paper have, from the theoretical research of the significance, standard and model of the strategic alliance stability, and through further analysis of the strategic alliance ' s instability representational type, secondly7 raised the critical elements involved in the interference of the strategic alliance ' s stability : the alliance partner ' s match ; the balance between profit and risk ; the co - operation of the alliance management ; the consistency of the alliance ' s objectives ; harmonization of the alliance ' s culture, thirdly, the critical measures that strengthens the strategic alliance ' s stability, consisting of : construction of the enterprise ' s core capabilities ; strengthening of mutual trust ; promotion of information management ; coordinating of alliance ' s organizational study ; promotion of the alliance ' s culture amalgamation
本文試圖尋找干擾企業戰略聯盟穩定性的關鍵因素，並提出加強戰略聯盟穩定性的關鍵措施。首先本文從戰略聯盟穩定性涵義、標準和模型進行理論研究，然後分析戰略聯盟不穩定性的表現類型，其次提出了干擾企業戰略聯盟穩定性的關鍵因素，即聯盟夥伴的匹配性、收益和風險的對稱性、聯盟管理的合作性、戰略目標的一致性、聯盟文化協同性。再其次提出了加強戰略聯盟穩定性的關鍵措施，即建設企業核心能力、增進聯盟相互信任、推進管理信息化、協調聯盟組織學習、促進聯盟文化融合。
