The scarce annual global solar radiation data of Henan Province were extended to recent 40 years (1960￣1997) by experimental formula, and direct solar radiation and scatting solar radiation data were calculated by another experimental formula for the stations with the only global solar radiation data.

首先把河南省不完整的太阳辐射资料，用经验公式推算到近40年（1960～1997年）的资料。并把只有总日射资料的站，利用经验公式，计算出直接辐射、散射辐射资料。

For dense grade the saturated-surface-dry method is more correct than the wax-enveloped method if fully soaped. For loose one, the latter is more correct than the former if the wax is not shed and the temperature is not too high. For sample with some holes, covered with talcum powder will be more correct, thus the talcum powder should be required for these ones, and the calculating formula should be amended referring to this paper.

研究结果表明，密级配试件表干法比蜡封法更趋准确，但试件应充分浸水；对于开级配试件，蜡封法结果比表干法更为准确，但要保证水不会由于蜡的脱落而进入试件，同时温度不宜过高；对于表面坑洞较多的试件，加滑石粉可以替代试件的开口空隙而使结果更加准确，故对沥青碎石试件最好强制添加滑石粉，而且计算公式应参考本文推荐公式进行修正。
