黑体的分析和研究

简单介绍了宇宙黑体。阐述了黑体所遵循的规律和特性，为科学研究提供了理论依据。在实际应用中，将目标为飞机，军舰等的热辐射，用本文介绍的空腔型黑体辐射热来等效，便于红外检测系统的标定与测试。

Analysis and Research of a Blackbody

Baed on the principle of the blackbody and its character, heat radiation from the objects,such as aircrafts and warships and so on can be considered equivalent to the blackbody source ofcavity type. In this way, the measurement and calibration of the IR systems can easily be done.
