Various gases of the atmosphere absorb about 70% of this upwelling radiation . 大气的各种气体大约吸收这种向上辐射的70。
The most obvious point to make about these diagrams is that the presence of radiation sinks . 这些图上最明显的一点是存在着辐射的汇集。
The effective injury ranges of these two kinds of nuclear weapon radiations may differ widely . 核武器的这两种辐射的有效杀伤范围可以相差很远。
The detectors of the emitted radiation are synchronized to their specific element's source . 发射辐射的探测器与它们的特定元素的激发源是同步的。
On such a large time scale the radiation parameterization will become more and more significant . 在这种较大的时间尺度上，辐射的参数化将变得越来越重要。
average radiant intensity is simply the total radiated power divided by 4π sterad. 辐射的平均强度简单地说是总的辐射功率被4立体角除。
Thus the absorption of a system is the fraction of the incident radiation which is absorbed by the system . 因而一个系统的吸收率就是被系统吸收的入射辐射的份额。
Bremsstrahlung produced at an internal target of the accelerator will have a maximum photon energy equal to ea . 在加速器的内靶上产生的轫致辐射的最大光子能量将等于Ea。
With the help of special radio telescope, the intensity of radiation can be measured in different parts of the sky . 借助于专门的射电望远镜，就可以测量天空中任何地方辐射的强度。
The ratio of the microwave radiation to the x-ray bremsstrahlung radiation is dependent on the density in the emitting region . 微波辐射与X射线韧致辐射的比值与发射区的密度有关。
