本文首先研究了移動通信現有的擴容技術，其次深入研究了tdma系統和cdma系統的基本原理，在此基礎上提出了利用gsm與寬帶cdma系統同頻傳輸實現系統擴容的方案。 -
Based on the object - oriented technique, this study defines four types of geographical event, i. e. expansivity, contraction, rebirth and vanishment events for management of land use data. and it further designed an object - superposition data updating model based on the land use feature of point, line and polygon ， which would take the advantage of the gis overlay function to effectly implement of updating spatial and attribute data
從面向對象的方法入手，定義了引起土地利用變化的擴展、收縮、新生與消亡四種地理事件，並分別按點狀地物、線狀地物和面狀圖斑的土地利用實體特徵設計了對象疊加更新模型，從而能利用gis強大的空間分析能力，來有效地實現空間數據和屬性數據的一致性更新。 -
