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(kuò)散率、時(shí)間對(duì)溫室土壤不同深度的溫度影響,可計(jì)算出任一時(shí)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(xué)的熱傳導(dǎo)方程,利用測(cè)試的地溫?cái)?shù)據(jù),選用差分法計(jì)算了土壤熱擴(kuò)散率,應(yīng)用sas軟件擬合了非線性方程,建立了日光溫室土壤溫度場(chǎng)的數(shù)學(xué)模型。
