Their composition and struture are studied by element analysis, IR, UV visible spectra and room temperature magnetic susceptibility.

并用元素分析、红外光谱、电子光谱、室温磁化率等对其组成和结构进行表征。

The IR light does, however, reflect off of any objects or people in the room, and the information carried by this reflected light is recorded by a holographic imager.
