  1. This dissertation aims to probe into the institutional changes and institutional clashes between the enlarging european union and the central & eastern european countries ( ceecs ), as well as to construct a tentative theoretical innovation to account for institutional interactions between them. supported by political neo - institutionalism and borrowing institutional concepts from nobel prize - winner douglas north, the dissertation is set against a background of the dual process of institutional expansion by the eu and active institutional convergence on the ceecs " own accords. starting from the positive and negative impacts triggered by eu enlargement on both the eu ' s and the ceecs " political, governance and economic institutions, the dissertation carries out a systematic study of the partial adjustments and comprehensive reforms on the part of the eu, as well as of the europeanized transformation of the domestic institutions in the accession countries

    本文以新制度主義政治學為理論支點，以歐盟通過東擴實現制度擴張及中東歐向歐盟制度主動趨同的進程為背景，以東擴引發的制度變遷和制度對撞為研究對象，從分析考察東擴進程對于雙方政治權力制度和經濟治理制度的雙向沖擊及正負面影響入手，系統研究了歐盟東擴引發的歐盟制度局部調整與全面改革、及中東歐新成員國國內制度的歐洲化轉軌之雙重進程，分析總結出東擴制度互動的規律、模式與渠道，並在此基礎上構築了一種解釋轉型國家與超國家機構之間制度互動的實驗性理論模型「錮囚鋒理論」 ，從理論高度上對現實規律進行歸納。
  2. The following aspects are involved in this dissertation : 1 ) properties of convergence of the network model under the circumstance of few rooms, the prediction of the early production tally with the growth of the fire in building on the whole while the prediction becomes most fallacious when the rooms increase to a certain number, for instance, 9. the solution of the net mass flux, positive mass flux and negative mass flux is improved and then mass conservation is strictly maintained so that the prediction of the software become more credible and reliable

    本文主要涉及以下幾個方面: 1 ）軟體計算收斂性態在房間數目很少的情況下，軟體開發的前期成果能在總體上成功預測建築火災的發展過程，當房間數目增加到一定的數目（如9 ） ，軟體計算將出現劇烈振蕩的問題，預測結果極不理想。本文改進了軟體對凈質量流量、正、負質量流量的求解，保證了三者之間的嚴格守恆關系。經過改進，軟體的預測結果更可靠，更可信。

  5. But in more situations the random variables generating counting processes may not independent identically distributed, and in all kinds of dependent relations, negative association ( na ) and positive association ( pa ) are commonly seen. the research and apply in this aspect are rather valuable. in chap 2 we prove wald inequalities and fundamental renewal theorems of renewal counting processes generated by na sequences and pa sequences ; in chap 3 we are enlightened by cheng and wang [ 8 ], extend some results in gut and steinebach [ 7 ], obtain the precise asymptotics for renewal counting processes and depict the convergence rate and limit value of renewal counting processes precisely ; at last, in the study of na sequences, su, zhao and wang ( 1996 ) [ 9 ], lin ( 1997 ) [ 10 ] have proved the weak convergence for partial sums of stong stationary na sequences. however product sums are the generalization of partial sums and also the special condition of more general u - statistic

    但在更多的場合中，構成計數過程的隨機變量未必相互獨立，而在各種相依關系中，負相協（ na ）和正相協（ pa ）是頗為常見的關系，這方面的研究和應用也是頗有價值的，本文的第二章證明了na列和pa列構成的更新計數過程的wald不等式和基本更新定理的一些初步結果；本文的第三章則是受到cheng和wang [ 8 ]的啟發，推廣了gut和steinebach [ 7 ] ）中的一些結論，從而得到了更新計數過程在一般吸引場下的精緻漸近性，對更新計數過程的收斂速度及極限狀態進行精緻的刻畫；最後，在有關na列的研究中，蘇淳，趙林成和王岳寶（ 1996 ） 》 [ 9 ] ，林正炎（ 1997 ） [ 10 ]已經證明了強平穩na列的部分和過程的弱收斂性，而乘積和是部分和的一般化，也是更一般的u統計量的特況，它與部分和有許多密切的聯系又有一些實質性的區別，因此，本文的第四章就將討論強平穩na列的乘積和過程的弱收斂性，因為計數過程也是一種部分和，也可以構成乘積和，這個結果為研究計數過程的弱收斂性作了一些準備。
  6.
