  1. In view of bearing capacity of the elastoplastic theory analysis, the author made a comparison between the achieved bearing capacity limit load pi / 4 of round base ( space problem ) and the limit load pi / 4 of bar groundwork foundation design ( plane problem ) from soil mechanics at home and abroad as well as foundation criterion, and explained why the value of formula in present design criterion from soil mechanics is inclined to be conservative. in the light of the author ' s many years experience of vibration test on the spot and the research work of relevant projects, the author worked over the dynamic pile testing of the bearing capacity of foundation and batholith, and gathered the parameter of dynamic analysis and testing. the author also talked over the difficult point of pile foundation design criteria in present batholith engineering world, i. e. the confirmation of batholith bearing capacity of pile end, from the following aspects : a ) confirmation of single axis counter - pressure strength of rock in house ; b ) f. e. m calculation of elastoplastic model ; c ) calculation of soil mechanics ; d ) deep well load test

    然後，對巖土工程領域至今尚未解決，甚至不為人注意的考慮地基變形的地基承載力問題進行了實用化的探討，提出了考慮地基變形的地基承載力上程計算方法；對基於彈塑性理論分析的地基承載力國內尚未見報道的空間問題得到了圓形基礎（空間問題）的承載力界限荷載p _ （ 1 / 4 ） ，並與國內外土力學專著及地基基礎設計規范中的條形基礎（平面問題）的界限荷載p _ （ 1 / 4 ） ，進行了對比，從而定量上解釋了目前設計規范引用土力學承載力公式值偏於保守的這一情況；根據本文作者多年從事現場地基工程振動試驗及相關課題的研究工作，本文以截頭錐模型模擬地基，對地基（巖基）承載力的動測法進行了研究，為各類地基（包括巖基） ，匯總了動力分析和檢測川的參數：針對日前巖土工程界應用樁基設計規范中的難點? ?樁端巖基承載力的確定問題，從巖石室內單軸抗壓強度確定、基於彈塑性模型的有限單元法計算、土力學計算及深斤載荷試驗四方面進行了深入討論；本文作者根據多年現場載荷試驗的工程實踐，對深井荷試驗裝置的核心部分? ?反力裝置，設計了側壁支撐反力加載系統，該加載系統具有實用、簡便、穩定及安個等優點。
  2. Now, the foreign and national departments of ship building and management are studying the auto - detecting and auto - spraying ( water - mist ) system of fire about the ship ' s main parts ( engine room ), and there are some foreign manufactories that have produced the relevant productions, but there are no similar productions in our contrary, so the st udy on the item ( the designing and study of water - mist fire auto - extinguishing system ) will supply a gap about national ship area fire, and it has high theoretic value and actual application significance. the mcu is main part of this system, and this system can detect automatically fire, show the place of fire and spray automatically water - mist

    目前，國內外船舶建造及管理部門正在投入人力和物力展開對船舶重點部位（機艙）火災的自動檢測及自動噴灑（水霧）滅火系統的研究，現在國外已有幾個廠家生產出相應的產品，但是在國內還沒有類似的產品出現，所以本課題（水基噴霧自動滅火系統的設計與研究）的研究可以說是填補了國內船舶區域火災的自動監測和報警以及自動噴灑（水霧）滅火裝置這個空白，具有很高的理論價值和實際應用意義。
  3. Data warehouse is a hot research area in 90s its main motif is to provide the decision - maker a powerful tool : gathering the data in pure consistent, relevant pattern, and making use of the data in managing analyzing, data - mining purposec that means that the decision - maker can use the tool to understand, grasp the situation of the business from different directions and forecast the future of it when using data warehouse, the processing speed determines data warehouse ' s practicability and processing ability the hoc ( highway decision center ) system realized before solves some key problems about intermediate scale data, mainly concentrating data warehouse performance coefficient when using hdc in large scale data, it encountered processing speed problem then the settlement of this problem becomes a major research point so, based on the former research achievements, the present task is to construct the renowned data warehouse architecture and its relevant algorithms, then adapts the system to the large scale dataset with data mining functions c this paper is a part of the research in order to construct the powerful system, a key problem is to cope with the processing - speed problem and the data space problem, etc, - caused by the large scale dataset and magnificent dataset this is also the core in the present data mining research this paper ' s motive is to design and realize a decision - tree classifier in the data warehouse system for large - scale dataset

    大型數據倉庫的處理速度問題目前是制約其推廣應用的關鍵所在，也是這一領域的一個重要研究課題，也正是我們當前工作的重點：在前期研究工作的基礎上圍繞提高大型數據倉庫處理速度問題，建立改進的數據倉庫系統模型和相關演算法，開發出面向中級以上企事業單位的、具有數據挖掘和分析能力的大型數據倉庫系統。建立大型數據倉庫所面臨的關鍵問題，是如何妥善解決實際業務數據的大規模、海量特徵所帶來的處理速度和空間等問題，這也是當前挖掘技術研究必然面對的核心問題。本研究的目的是設計並實現大型數據倉庫系統中的分類數據挖掘工具? ?決策樹分類器，主要工作是在綜合了解現有決策樹分類演算法的研究情況的前提下，對決策樹演算法適應大規模數據集的問題進行探討，力求設計出能較好地適應大規模數據的分類器演算法。
