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。

In the experiment, the axes of fibers or organic crystals were arranged first parallel and then Perpendicular to the incident radiation.

试验中分别将纤维或晶体的轴向排成与入射光相平行和垂直的二种方式。

Various extinction observations indicate that the absorption coefficient depends on the wavelength, snow depth and the incident radiation intensity.

不同的消光观测资料说明，吸收系数对于波长、雪深以及入射辐射强度具有选择性。

When the device is aligned so that its pits are pointing straight at the sun, most of the incident radiation goes down them to their bottoms.

There were no injuries and little release of radiation from that incident, which remains the worst commercial nuclear accident in U.S. history.

Correspondents say the incident has highlighted the fragility of the rescue operation at Fukushima two years after the meltdowns caused a major release of radiation.
