  1. 3. take the lrdmis as info source to discuss the combination of gis and specialty model in information system, by the means of spatial overlay analysis the land use status movements, carried a analysis to number and quality structure of region land type by the means of landscape analysis, and principal analysis was utilized to evaluate experiment area ' s land quality hierarchy., all the work provided a scientific foundation and technological support for experiment area synthetic management and planning

    以lrdmis為信息源，對信息系統中gis與專業模型的結合應用進行了探討，通過空間疊加分析方法對土地利用現狀變化進行了監測，應用景觀分析方法對區域土地類型的數量與質量結構進行了分析，應用主成分分析法進行了試區土地質量分等定級，為試區綜合治理規劃提供了一個新型的技術支撐體系。
  2. We use the correlation of data between the neighbor scan lines to get the overlay pixel number, and then remove the overlay data. the bilinear interpolation method is applied to assign the pixels with the overlap data. the result shows that the data overlay phenomenon is removed, image quality is improved, and pixel value has been enhanced

    此外，對于modis遙感影像中存在的邊緣區域數據重疊問題，則利用數據間的相關性計算條帶間各列像元的重疊數量，然後刪除重復部分，並經灰度重采樣后得到結果數據，實驗表明影像數據的重疊現象明顯消除，從而改善了影像的質量，增強了數據的使用價值。
  3. 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。
  4. We also propose another mobility management scheme ( mfmip ) to overcome the ping - pang effect when mobile host mobile access internet in the future wireless overlay network, where a number of networks offer similar coverage and bandwidth on the same overlay level. 5

    該演算法根據移動主機的位置信息、運動方向、速度，以及無線網路屬性，動態選擇最佳基站進行注冊，有效地克服了採用標準協議產生的乒乓效應，大大提高了吞吐性能。
  5. To solve the former problem, hiarachical cellular system ( hcs ) could be applied, where macrocells cover low - teletraffic areas and serve slow calls, while microcells overlay high - teletraffic areas and serve fast calls. by this means, better spectrum efficiency can be achieved and the number of handoffs can be decreased

    對於前者，採用多層蜂窩系統（ hcs ） ，使得宏蜂窩覆蓋低話務量地區並為快速呼叫提供服務，而微蜂窩覆蓋高話務量地區並為慢速呼叫提供服務，這樣既保證較高的頻譜利用效率，又能有效地降低呼叫的切換次數。
