摘要
文中建立了一种适合于晴天或天空中有云复盖时光裸地面土壤热模型。利用能量守恒列出求解地表温度的热动平衡方程。其中各能量项采用较为普遍、精确度较高的实用表达式。为了验证,作者进行了有关物理量的实际测量。理论上求得的土壤表面温度与实测温度之差小于3度。
A thermal model suited for the nude ground soil at the condition of clear or cloudy sky has been established. Based on the principle of conservation of energy, a thermal dynamic equilib- rium equation used to gain ground surface temperature, with each energy phase being more ac- curate and more general practical expression, has been developed. Relevant physical quantities have been measured for verificaiton. The results indicate that the difference in the ground sur- face temperature between the theoretical value and the measured one is less than 3K.
