The geological factors are important besides them, which are related to the loess landslide and evolution of gullies, specially for bedrock folds, bedrock joints and loess joints. in field, the data of the bedrock elevation in the three sheets combined with the research from south to north lively were got by gps12xlc pocket locator, the type and its evolution of bedrock, loess landslides and distribution of hydrographical net were explored too. at office, the synthetic analysis and contrast were used including the simulating analysis about the data by mapinfo 6. 5, software of gis, discussion and communication with experts, in order to demonstrate and reveal the rules between the loess landforms and its pale bedrock landforms and the impact of structure on erosion interiorly in shaan bei
在野外，以代表調查區和路線調查相結合的方法，利用gps12xc型手提式定位儀採集基底高程數據，實地觀察基底地層產態變化規律和特徵，觀察黃土地貌、黃土崩塌、水系展布及土壤侵蝕等與地質構造之間的關系；在室內主要進行綜合分析與對比，利用gis系統的mapinfo6 . 5軟體對採集數據模擬分析，並將認識成果與其他專家學者進行交流和探討，從而論證和揭示陜北黃土地貌南北縱向分異與基底古樣式關系特徵及水土流失與構造因素之間的內在規律。 -
The pointer from an index row in a nonclustered index to a data row is called a row locator
從非聚集索引中的索引行指向數據行的指針稱為行定位器。 -
The structure of the row locator depends on whether the data pages are stored in a heap or a clustered table
行定位器的結構取決于數據頁是存儲在堆中還是聚集表中。 -
By using high - speed data acquisitioning unit designed specially to capture travelling waves of transient current, using global positioning system ( gps ) to supply high precise time tagging for both ends, using wavelet transform theories to identify the head of the travelling waves, the fault locator can realize high precise double - ended travelling waves location
該測距裝置採用專門設計的高速采樣單元捕獲暫態電流行波信號，用全球定位系統（ gps ）為線路兩端提供精度高達1 s的統一時標，用小波變換理論識別暫態電流行波波頭信息，從而可以實現高精度的雙端行波法測距（ 150m ） 。 -
In computer graphics, a locator device with a flat surface and a mechanism that converts indicated positions on the surface into coordinate data
在計算機圖形學中，一種定位裝置，它有一塊平板和一個把該面上所指示的位置轉換成坐標數據的機構。 -
At the same time j2ee platform technologies are discussed deeply, such as j2ee platform technologies, communication technologies, ejb component technologies and so on. the design model based on the mvc frame is applied in the system development, so that the separation between the present logic and the business logic in the application is realized. finally, according to the problems found in the development process, the paper explains particularly the kay technologies in the realization : the uniform naming service is realized by realizing the service locator partten using the value object pattern, all the status data is encapsulated into a serializable object, then transferred among the client, sessionbean and entitybean in order to decrease the potential network traffic caused by reference of entitybean ; in order to improve the performance of data storing and taking, we introduce the facade model to escapsulate the ejbs which delegate the data model
本論文結合了杭州市財政局的會計人員從業資格管理系統的升級項目，研究了基於j2ee的ejb組件模型的多層分散式體系結構的設計與實現：深入探討了三種分散式處理技術（ rmi ， corba ， com ）的區別，將j2ee平臺的ejb技術與windowsdna體系的com +技術從多個角度進行了比較；詳細闡述了在系統開發過程中j2ee平臺的幾項核心技術（如： j2ee平臺的服務技術、通信技術、 ejb組件技術等）的應用；引入了源於mvc三部件框架的設計模式，實現了應用中表現邏輯與業務邏輯的分離；最後，結合在開發過程中遇到的問題，詳細解釋了開發過程中實現的關鍵點：用servicelocator模式實現了統一的命名服務管理；運用valueobject模式將所有狀態數據包裝成一個可序列化對象vo ，然後在客戶機、 sessionbean與entitybean之間傳遞，減少了使用實體bean造成的潛在網路通信量；以及引入sessionfacade模式，用sessionbean封裝了entitybean ，改善了數據存取的性能。
