摘要
利用１９９２年我国大陆１０个日射站点的逐时和逐日的散射日射、总日射辐照量记录，在小时散射成分与小时晴朗因子ＫＴ以及日散射成分与日晴朗因子ＫＴ之间建立了相关关系，对其误差进行分析，并与国外同类工作的结果作比较，表明这类关系是有地区差异的，还与大气浑浊情况有关。所得关系式可供利用逐时或逐日的总日射辐照量推算相应时段的散射辐照量。
relationship between the hourly diffuse and hourly clearness index kT are established.based on hourly pyranometer and pyranometer with shading ring data from ten locations of China in 1992. Daily diffuse correlation is also developed from the same data.The errors are analysed. We compare these works with the same kind of works done in other countries.It is shown that there are regional differences in these kinds of relationship.due to atmospheric turbidity.
