A family of unidentified infrared emission (UIE) bands has been observed throughout the Universe. The current observed spectral properties of the UIE bands are summarized. These properties are discussed in the frameworks of different models of the chemical carriers of these bands. The UIE carriers represent a large reservoir of carbon in the Universe, and play a significant role in the physical and chemical processes in the interstellar medium and galactic environment. A correct identification of the carrier of the UIE bands is needed to use these bands as probes of galactic evolution.

在整个宇宙中都观测到了一族未确认的红外发射（UIE）波段。总结了目前观测到的UIE波段的光谱特性。在这些波段化学载体的不同模型框架下对这些特性进行了讨论。UIE载体是宇宙中碳的一个巨大储存库，并且在星际介质和星系环境的物理和化学过程中发挥着重要作用。要将这些波段用作星系演化的探测器，就需要正确识别UIE波段的载体。
