于是得到各种透明系数P_2状况下太阳直接辐射通量密度随大气质量变化的平均关系。
Thus the averaged relationships between the flux density of the direct solar radiation and the air mass under various coefficients of transparency P2 were obtained.
土壤热通量密度的比例只占净辐射的5%左右。
证实利用地面水汽压资料可相当精确地计算出各地的可能太阳直接辐射日平均通量密度。
The results show that the daily average flux-density regime can be calculated quite accurately for various parts of the country by making use of the surface vapor pressure data.
