摘要基於盾構掘進的已有歷史數據，建立數據庫對盾構掘進數據進行管理，分析挖掘影響盾構姿態的主要因素，並得出地質條件與盾構掘進千斤頂推力之間的關系，更有效地實現盾構的姿態控制。 -
We must think of three factors to make a best capital structure. first factor is margin tax shield, namely, the ratio of firm value ' s increment for liability and the increment of liability blow. second factor is finance crisis net lost that is bought in future. thirdly. we must make much of the market action and adjust capital structure

Part 3 is the empirical analysis to the influencing factor of listed company ' s capital structure in china, specifically with spss software and main composition analysis method, it correlated dividend policy, income tax, equity structure, non liability tax shield and income variation level of company, company growth, company ' s profit ability, asset structure, company ' s scale with capital structure ( the contents embrace btdr, bldr, bsdr ), we make the conclusion as follows : comparing with the research result of influencing factor of the company ' s capital structure of the developed country, the influencing factors of the listed company ' s capital structure in china have partial similarnesses
第三部分中國上市公司資本結構的影響因素分析這部分是本文的重點之一，具體是採用spss11 . 5軟體，用主成分分析法與多元回歸分析，對公司的股利政策、所得稅、股權結構、非負債稅盾、收入變異程度、公司的成長性、公司盈利能力、資產結構、公司規模與代表資本結構的變量（ btdr ， bldr ， bsdr ）作相關研究，結果是：和發達國家公司資本結構的影響因素研究結果相比較，我國上市公司資本結構的影響因素存在部分相似性。 -
The famous project of gas transiting west to east and the cross - river tunnel of huangbu river in shanghai also will be constructed with this technique, which is under the plan. among the shield tunneling methods, up to now, earth pressure balanced shield tunneling ( epbs ) is the most universal type, and it is very certain that the epbs method adopt to our country increasingly. the key factor to success in epbs is converting the muck which is lack of fluidity excavated from the cutter face to the plasticity soil. but when the shied tunneling machine advancing, it is considerably difficult to reach this requirement because of the ground soil condition, which is consist of stiff clay, silt, weathered rock, and so on
近些年來我國城市地鐵建設迅速發展，盾構施工法作為一種安全而又環保的施工方法得到了廣泛的使用，另外在黃浦過江隧道，西氣東輸的穿黃隧道等工程也在使用盾構隧道施工技術。這其中土壓平衡式盾構在我國的使用最為普遍，成為地鐵隧道施工技術的主流。土壓平衡式盾構施工成功的關鍵是要將開挖面切削下來的土體在壓力艙內調整成一種「塑性流動狀態」 。 -
2. it establishes the distance valve value model of interactions between different tourism regions, and concludes that distance being the crucial factor that decides the nature and degree of tourism spatial competition among regions. 3. it introduces a new concept concerning spatial competition - " tourism resource assembling shield ". then by comprehensive utilization of the following six kinds of analytic techniques - index r, index 3, index y. accessibility index, average directory length and intensity index, it makes a relatively comprehensive analysis and evaluation of the spatial distribu
