central subsystem
解釋
中央子系統-
The system stores spatial data and characteristic data into central database, and provides services to users in server / client mode. as the research emphases of this thesis, several key sub - systems are designed and realized. the digital map input and maintenance subsystem performs format conversion, editing and updating of spatial data ; the rail - track video playing subsystem uses video recording as reference data, then plays, inquires and traces the corresponding frames in synchronous to the scaled mileage, realizing the query of the active picture frames ; the digital map query subsystem fulfills the map query, preview and spelling of digital map orthograph
其中，地形圖輸入與維護實現了數字地圖的格式轉換、編輯處理以及空間數據的更新操作，解決了不同格式空間數據的互相轉換問題；線路錄象播放將線路錄像數據作為系統的一種索引數據，活動影像的畫面與里程相對應，實現了基於線路錄像的播放、查詢和檢索的功能，實現了基於活動畫面的查詢檢索功能；數字地圖子系統完成了圖形查詢、數字地圖與線路正射圖像瀏覽、圖幅拼接等功能。 -
A method is proposed to construct a localized active functional space from the density matrix of a large system. the large system is partitioned into central and surrounding areas. the active functional space is mainly localized on the central area. it contains all basis functions centered at the central area and all the orbitals which consist of the basis functions localized in the surrounding area and interact with the basis functions in the central area to a certain extent. an integral number of electrons are involved in the localized active functional space which can be considered as a relatively independent subsystem in the large system and for which formally isolated quantum chemical calculations can be performed. the related program has been coded and is checked through calculating the number of 4
報道了從大體系的密度矩陣出發構造定域于指定局部的活性泛函空間的方法和程序。將大體系劃分為中心區和環境區，活性泛函空間包含中心區的基函數及與其有相互作用的環境區軌道，容納整數個電子，構成大體系的一個相對獨立的子體系，可以在其中進行獨立的量子化學計算。通過計算鑭系氯化物和水合離子的4 -
