在裸地下墊面時,晴天潛熱佔到凈輻射的60 ,顯熱交換只佔到19 ,在陰天凈輻射同樣主要消耗于土壤蒸發,與晴天不同的是在陰天土壤熱通量積分值小於零,表明土壤在向外釋放熱量;平均狀況下,潛熱、顯熱和土壤熱通分別佔到凈輻射的67 、 21和6 。The closed screen prevents the heat dispersion by radiation or heat exchange, thus the system can reduce the energy consumption
遮陽幕閉合后能有效防止溫室內熱能通過輻射或熱交換形式外溢,從而降低溫室耗。( 3 ) compared with bare soil, income of net radiation declined, apparent heat weakened and latent heat exchange were almost disappeared on the soil surface with film
( 3 )薄膜覆蓋于土壤表面后,與未覆蓋的土壤相比,地表凈輻射r _ n收入下降,顯熱交換p減弱,潛熱交換le趨于零。Soil heat flux from atmosphere to soil is about 5 % of net radiation on a clear and cloudy day and soil discharge energy to atmosphere on a rainy day above the same field. in brief, average latent heat, sensible heat and soil heat flux is 40 %. 50 % and 10 % of net radiation respectively
在春小麥下墊面,晴天能量主要消耗于農田蒸散,而在陰天顯熱交換大於農田蒸散耗熱;在晴天和陰天大氣向土壤的能量傳輸均維持在凈輻射的5左右,雨天時,土壤熱通量為負值。Roadbed construction on permafrost will give substantial disturb for the heat and mass transfer balance between the ground surface and atmosphere, usually, roadbed construction increases the amount of absorbed heat via vegetation removal, solar radiation and increased role of water activities in the adjoining area, then cause the local degradation of the permafrost underneath, as a result may lead to damage of the roadbed
多年凍土區道路的修築,改變了原來天然地表與外界的熱交換關系,通常由於地面植被的破壞、太陽輻射和水的影響,導致進入地層中的熱量增加,引起多年凍土區凍土的融化,從而導致路基面破壞。Single - layer model is convenient to apply but the unclear relationship between radiative and aerodynamic temperatures is still a bottleneck in this field. a new method was developed to derive reliable surface heat fluxes from radiative temperature viewed from arbitrary zenith angle. aerodynamic and radiative temperatures are connected through a so - called optimum component fraction ( ocf ) parameter - the fraction of vegetation in the field of view when the two temperatures are equivalent in oblique viewing
