The adjustment of direct consumption coefficients is one of the key problems for input-output analysis.
直接消耗系数的调整一直是投入产出研究者们关注的热点之一。

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.
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。
