除非在曝晒过程中对辐照度进行了直接测定，否则不要报告辐照度或辐射能。
Do not report irradiance or radiant exposure unless direct measurement of irradiance was made during the exposure.
这是一种利用太阳辐射能直接分解水制氢的光-化学转换方式。
This is a direct use of solar radiation to decompose water hydrogen which called light - chemistry conversion way.
通过辐射能信号能够更加直接地反映燃料量或者燃烧品质的改变。
The radiant energy can reflect the change of the fuel rate or the quality of combustion more directly.
因为直接来自头顶，阳光辐射能的密度升高也就是说阳光集中照射在更小的地表区域。
The density of the solar radiation is higher because it's coming from directly overhead - in other words, the sun's rays are concentrated over a smaller surface area.
