- soil heat convection 土壤热对流
- Since solids do not move, heat convection does not occur in solids. 由于固体不会运动,所以热量无法在固体中进行对流转移。
- The main parameterof heat convection process is heat transfer coefficient. 反映对流换热过程特性的主要参数是对流换热系数。
- A Study of Effects of the Concrete Mulch on Movement of Soil Water and Soil Heat Transfer. 硬覆盖对土壤水热传输及作物生长发育影响的试验研究。
- The trial test indicated that NTS was unfavorourable for seed emergence and the soil heat flux was lower than the other tillages obviously. 试验表明,免耕覆盖的土壤温度不利于豌豆的出苗,且土壤热通量明显小于其它耕作方式。
- The surface energy is not balance in grassland and Gobi.In grassland the sum of LE, Hs and soil heat flux is smaller than RN. 在山区草原,晴天潜热通量是土壤热通量的三倍多,感热通量与土壤热通量差异很小,净辐射主要用于蒸发、蒸腾;
- The difference between RN and sum of LE, Hs and soil heat flux on a cloudy day is bigger than that on a clear day as well as it in Gobi is bigger than that in grassland. 两地均存在能量不平衡现象,草原感热、潜热、土壤热通量之和小于净辐射,戈壁感热、潜热、土壤热通量之和大于净辐射,戈壁能量不平衡大于草原。
