土壤热扩散率 meaning in Chinese

soil heat diffusivity soil thermal diffusivity

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
模型中充分考虑了土壤热扩散率、时间对温室土壤不同深度的温度影响，可计算出任一时间、土壤不同深度的温度。
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
基于传热学的热传导方程，利用测试的地温数据，选用差分法计算了土壤热扩散率，应用sas软件拟合了非线性方程，建立了日光温室土壤温度场的数学模型。
