radiant surface

The paper describes the measuring technique of infrared radiant heat flux density reached the surface or absorbed by the surface of spacecraft during thermal balance test.

文章介绍了在航天器热平衡试验中到达航天器表面或被其吸收的红外辐射热流密度的测量技术。

Such a surface would reflect no radiant energy, and hence would appear black in color.

这种表面不会反射辐射能, 因此呈现黑色.

For a fixed set of conditions, any free surface emits radiant energy of varying wavelengths.

在一定的条件下, 任何自由表面均会散发各种波长的辐射能.

No surface can absorb more than all of the radiant energy which strikes it.

表面所能吸收的能量不可能大于投射到它上面的全部辐射能.

Clouds return radiant energy to the surface primarily via the atmospheric window.

云主要通过大气窗区向地表辐射能量.
