With the help of rs, gis, gps, the interpreted maps of 1985 and 2000 remote sensing images overlay the digitized soil map to get the area of very kind of soil that the city covered during its progress of urbanization. the function of gis are elaborated, such as managing spatial data and attribute data, spatial analyzing and outputting ultimate maps to get the reduced number of nanjing population carrying capacity and its spatial distribution because of the expansion of city
利用rs 、 gis和gps技術，對南京市1985年和2000年遙感圖像解譯，得到南京市城市擴展圖，把擴展圖和南京市土壤圖疊加；充分發揮gis技術在管理空間、屬性數據和空間分析與輸出成果圖等強大功能，計算出南京市由於城市擴展而使人口承載力減少的數量及其空間分佈。 -
By using of erdas and arcgis softwares, two tms and one etm + of xuzhou city in 1994, 2000 and 2003, together with a 1 : 50000 topographic map of xuzhou city, the built - up expansion of xuzhou is studied
摘要利用erdas及arcgis軟體，以徐州1994 ， 2000及2003年的遙感圖像為數據源，結合1 : 5萬地形圖研究徐州市建成區的擴展情況。 -
In order to study the operation characteristics of hpacdhws, distributed parameter simulation models of the fin heat exchanger and the plate heat exchanger are built up. the compressor model is founded in map - based method, and the thermodynamics expansion value model is built up in force balance method. the dynamic system model is the efficient connection of all component models by laws of equalization of mass, momentum and energy
為了研究hpacdhws的運行特性，本文利用分佈參數法分別建立了翅片管換熱器和板式換熱器的動態數學模型，採用圖形法和力平衡法分別建立了壓縮機和熱力膨脹閥的集總參數計算數學模型，並基於質量、動量和能量守恆定律等約束條件，建立了hpacdhws的動態模擬模型。
