| Abstract: | Measurement and analysis were conducted on soil temperature of a greenhouse, located in Beijing Agriculture College. The paper presents a mathematical model of unsteady heat transfer of soil temperature, calculates the heat diffuse coefficient of soil by difference method, and fits equation on experimental data by SAS. The model shows good agreement between the calculate values and measured data, affords means and evidence for further analyzing of the heat property on soil in greenhouse. |
