Taking into consideration of the factor include heat diffuse coefficient of soil and time , which affect soil temperature of differential deep , the model can calculates temperature of any time in different depth 模型中充分考慮了土壤熱擴散率、時間對溫室土壤不同深度的溫度影響,可計算出任一時間、土壤不同深度的溫度。
It presents a mathematical heat transfer model of air and soil temperature in greenhouse basing on the theory of transmission of heat . the model calculates the heat diffuse coefficient of soil by difference method and establishes regression equation on experimental data by sas 基于傳熱學的熱傳導方程,利用測試的地溫數據,選用差分法計算了土壤熱擴散率,應用sas軟件擬合了非線性方程,建立了日光溫室土壤溫度場的數學模型。
