The transmitted radiation is either absorbed or reflected at the Earth's surface.

发射的辐射要么被吸收，要么在地球表面反射。

Normally the spectrum is given as a function of transmittance, the quotient of the intensity of the transmitted radiation and the incident radiation.

在测量范围内可以产生单色辐射光学系统的分光光度计也可以使用。通常光谱是透光度（透射光强度与入射光强度之商）的函数。

Provided is a power line communication device which can suppress increase of unnecessary radiation even when signals are continuously transmitted.

提供了一种电力线通信装置，即使当连续传送信号时，该电力线通信装置也可以抑制不必要的辐射的增加。

The power needed to operate the device is sufficiently small that it can get all the juice it needs from stray (or transmitted) electromagnetic radiation or miniature solar collectors.
