The study on the development model of agricultural science and technology park : make a comprehensive survey of the agricultural science and technology park development, statistical data on the agricultural science and technology park in the year of 2002 was applied to do macro analysis, with the result of development problems and propose the settlement. this study is conducted based on typical case study and theoretical analysis from the aspects of growing background, overall effect, operating model and the driving force in four national agricultural science and technology parks : shandong vegetables demonstrating park, henan xuchang national park, gansu dingxi park and beijing shunyi three - hi agricultural pilot model area. then analyse and sum up the general laws and different points. the creative research of this paper lines in raising the new theory of sci - tech agricultural industry organization for the first time, build up the theory analysis framework for agricultural science and technology park ; according to the theory analysis framework, sum up the development general model from choosing the national agricultural park in typical region ; build up th
運用典型案例剖析與理論分析總結相結合的方法，分區域按照發展成效在全國范圍內選取山東壽光蔬菜高科技示範園、河南許昌農業科技園區、甘肅定西旱作生態型農業科技園區和北京順義三高農業示範區，從園區的成長背景、建設發展的總體成效、運作模式和園區發展的動力等幾個方面對農業科技園區的發展進行了深入研究，並對園區發展模式的共性規律和差異之處進行了分析歸納；本文創造性的研究在於：首次提出了科技農業產業組織理論，構建了農業科技園區理論分析框架；根據這一理論分析框架，通過選取典型區域的國家農業科技園區進行實證研究，總結歸納了園區發展模式共同特徵並進行了差異分析；首次提出了適用於不同評價對象和評價意圖的三套國家農業科技園區評價指標體系，並創造性運用多元統計分析方法和系統分析方法對國家農業科技園區進行綜合評價。 -
Based on piecewise linear model, this paper proposes an estimation method that first estimates the slope of linear variant and the channel impulse response at the middle time of the current ofdm symbol using pilot sequences, and then estimates the whole channel impulse response through the estimated parameters
該演算法首先利用導頻序列估計出當前ofdm符號間隔內通道線性變化的斜率和中間時刻通道的沖激響應值，然後根據線性模型利用估計出的參數得到當前符號間隔內所有時刻上的通道沖激響應。 -
