In ddmm, the rdb is taken as the bottom storing medium and the upper xml view is set up for data exchange and direct application under internet / intranet environment. based on ddmm, the multi - tiered and bi - directional data integration technique between xml and rdb, is studied systematically and in detail, and the reciprocal data accessing and exchange between rdb and xml is carried out on respectively three levels : static data transformation, dynamic data query and synchronized data update. the infrastructure for manufacturing informationlization will certainly be internet / intranet, and xml has been a factual standard for data representation under internet / intranet environment
製造業信息化的基礎平臺將是internet intranet ， xml （ extensiblemarkuplanguage ，可擴展標記語言）已經成為internet intranet環境下數據表達的事實標準，而目前企業大量數據仍存在於佔主導地位的關系數據庫（ relationaldatabase ，簡稱rdb ）中，如何在rdb與xml之間架起數據交換與數據操作的橋梁，已成為製造業在internet intranet環境實現信息化迫切需要解決的突出問題之一。 -
Main achievements in this thesis are : one, by thoroughly studying the original ocean - bottom re - positioning software and corresponding algorithm, the author replant the original software from unix workstation to the ms windows environment with vc + + 6. 0 and visual fortran 6. 0 co - programming technique. two, the corresponding algorithm about picking up the first - arrivals and relocating of geophones are studied and realized
對原海底檢波器二次定位軟體進行了全面細致的研究剖析，並對其相關原理進行了較深入的研究，利用visualc ~ （ + + ）與visualfortran語言混合編程技術，將原來基於unix工作站環境的海底檢波器二次定位軟體移植到了微機環境下的mswindows平臺上。 -
Chapter 1 introduce the development situation of the marine multi - component seismic exploration technology in our country and abroad. chapter 2 sum up the structure of the system. chapter 3 to 6 includes the design and function of the homemade sample equipment and the advantage of its key technique. just as omnidirectional geophone struture, ocean bottom cable, data acquisition unit and recording system etc. chapter 7 carefully instructs test situation of converted wave acquisition on the sea and appreciates the data quality
第一章主要介紹了目前海上多波勘探技術的國內發展概況及市場需求，第二章對整個系統的構成及各部分的功能進行了簡要的總結，第三章至第六章詳細討論了各功能模塊的原理、技術指標及創新點，包括各項關鍵技術的突破，如三分量萬向平衡裝置的理論計算及設計，數字包電路設計原理，鎧裝結構電纜的設計及系統主機的特點等。 -
Fabrication of nanostructures based on spm as an extension to spm imaging, referred to as scanning probe nanofabrication ( spn ) is an emerging technique undertaken at labs in the past ten years that comprises manipulation of atom or molecule in a bottom - up paradigm and scanning probe lithography ( spl ) in a top - down paradigm. in chapter one, in the light of decentralized experimental data in this respect, the author, classify in an analytic approach the literature concerned as electrical spl, mechanical spl, thermal spl, and optical spl in terms of different mechanisms of interplay between a probe and a surface of a sample, after describing the most important of this type of microscopy, i. e., scanning tunneling microscopy and atomic force microscopy
由於這項技術的實驗數據比較分散，因此，作者在論文的第一章里首先介紹了掃描探針顯微鏡的兩個最重要的類型，即掃描隧道顯微鏡和掃描原子力顯微鏡的工作原理；然後根據加工方式的不同把它分為自下而上的掃描探針原子（分子）操縱與自上而下的掃描探針刻蝕兩大類；而根據掃描探針與樣品的不同作用機理，對掃描探針刻蝕加工又進行了歸納與綜述，對其特殊的加工方法作了原理性的介紹，並分析了目前存在的共性問題與應用前景。
