We got the spatial distribution map of population density by spatial interpolation, in which the population data are distributed on the grids. the results of the distribution of interpolated based on gis is closed to a real population distribution. the combination of the spatial interactive models and a shortest path algorithm for public transit network is analyzed by supermarket ' s accessibility based on pedestrianism and public transit. this methods may be used to investigate potential supermarket ' s locations. the quantitative analysis about the supermarket ' s market area is realized based on trade mode of lashmanan and hansen, which mainly includes spatial distribution of population, traffic accessibility and free competition between different firms
文中應用空間內插技術實現了人口數據空間分佈化，將人口數據通過空間插值分佈於研究區域內，使人口空間分佈更接近實際；應用公交最短路徑演算法及空間相互作用模型實現了基於步行和公交出行的超市可達性，將交通對超市選址的影響定量化，方便了方案的比選；在綜合考慮人口空間分佈、超市交通可達性、現有零售商業競爭態勢的基礎上，基於拉、漢購物模式實現了超市商圈定量分析。 -
The task in the open loop system is to get lpg injection duty ratio in pre - set two dimension map according to practical engine operation condition, while the task in the closed - loop system is to calculate lpg injection duty ratio by the approaching increment method or the proportion and integral ( pi ) controller according to the signal of the oxygen sensor. to eliminate the oscillation phenomena of the signal of the oxygen sensor in low - speed condition, this paper develops the stable increment method
開環階段根據實時工況參數對事先制取的噴氣占空比map圖執行取值操作；閉環階段根據氧傳感器反饋信號通過增量逼近法或pi環節計算輸出適合即時工況的噴氣占空比值；為解決低速振蕩現象，本文運用固定增量法，對系統進行低速振蕩微調。
