  2. This paper consists of three chapters. the first one is the preparatory knowledge underlying this paper, including the basic concepts of the piece - wise deterministic markov processes ( pdmp ), the renewal equation, the key renewal theorem and some results about the classical risk model, which come from [ 2 ], [ 8 ] and [ 9 ]. the second one introduces the results about the general ruin probability in a kind of continuous - time risk model with the deficit - time geometric distribution of inter - occurrence times, in which claim sizes are discretly distributed. these come from [ 6 ]. the main body of this paper is the third one where we derive lundberg bounds, cramer - lundberg approximations to the ruin probability and finite - horizon lundberg inequalities

    本文共三章，第一章是奠定本論文基礎的相關知識，包括逐段決定馬爾可夫過程的一些基本概念、更新方程與關鍵更新定理的內容以及經典風險模型的介紹，主要取自[ 2 ] 、 [ 8 ]和[ 9 ] 。第二章介紹了該風險模型在索賠額分佈為一般分佈下的破產概率的一般表達式及相關定理，內容來自[ 6 ] 。第三章是本文的主體，求得了該模型的破產概率的lundberg界， cram r - lundberg逼近以及有限時間破產概率的lundberg不等式。
  3. Based on the above background and under the support of tianjin natural science foundation project : intelligent fiber amplifiers and light sources, tianjin natural science foundation project : ( c + l ) broadband fiber amplifier and nankai - delta ( tianjin ) project : development of gain flattened erbium - doped fiber amplifiers, this dissertation is mainly focused on the study of novel gc - edfa, gain and nf ( noise figure ) improvement of edfa, light sources, multi - wavelength fiber laser and voa ( variable optical attenuator )

    基於以上背景，在天津市重點基金項目? ?智能型光纖放大器和光源的研究、天津市重點基金項目? ? （ c + l ）超寬帶摻雜光纖放大器和南開-達爾泰（天津）項目? ?開發增益平坦的摻鉺光纖放大器的支持下，本論文主要圍繞新型gc - edfa 、 edfa性能的優化、增益控制用光源、多波長光纖激光器以及可調光衰減器等課題進行了理論和實驗研究。
  4. Meanwhile, with the development of wdm / dwdm communication systems, more and more attention is paid on the edfas with broader bandwidth, good gain and noise feature, and gain clamping, etc. according to the tianjin natural science foundation project : intelligent fiber amplifiers and light sources, the tianjin natural science foundation project : ( c + l ) broadband fiber amplifier and the nankai - delta ( tianjin ) project : development of gain flattened erbium - doped fiber amplifiers, this dissertation is mainly focused on the study of novel gain - clamped edfa, light sources, multi - wavelength fiber laser and variable optical attenuator for gain - clamped usage, gain and noise improvement of edfa, and broadband edfa

    Wdm / dwdm通信系統的發展又需要edfa具有更大的帶寬、優良的增益和噪聲特性和增益控制等功能。基於上面的情況，並結合天津市重點基金項目? ?智能光纖放大器光源的研究、天津市重點基金項目? ? （ c + l ）超寬帶摻雜光纖放大器和南開-達爾泰（天津）項目? ?開發增益平坦的摻鉺光纖放大器等課題，論文主要圍繞新型增益控制edfa 、增益控制用光源、多波長激光器及可調光衰減器、 edfa性能優化和超寬帶edfa等方面進行了理論和實驗研究。
  5. But statistically, the former manifests significant discriminant power while the latter does not. second, the above empirical results also show that the edf model has good performances in such developed countries as the u. s. a., etc, however, it is inappropriate to apply the edf model in china directly. third, the empirical formula in the new accord, which links the corporate default risk with corporate asset return correlation coefficient, cannot capture the credit risk of china ’ s listed companies very well

    從中本文得到了如下的一些結論:第一，從直觀上看，基於會計信息的logit模型對我國上市公司的信用風險具有明顯的判別能力，基於市場信息的期權理論模型? edf模型也似乎具有一定的判別能力;但從嚴格的統計意義上來看， logit模型仍然具有顯著的判別能力，但edf模型的判別能力不明顯;第二，本文的實證結果同時也說明，雖然kmv公司提出的edf模型在美國等發達國家的應用具有較為良好的表現，但將edf模型直接應用到我國顯然並不適合;第三，新巴塞爾協議中將公司的違約風險與公司間資產收益率相關系數聯系起來的經驗公式也不能很好地捕捉中國上市公司信用風險方面的市場信息。
