摘要
介绍了有关宇宙微波背景辐射（ＣＢＲ）观测和理论研究的最新进展。叙述了基于ＣＯＢＥ卫星的观测宇宙学，包括对背景辐射谱、各向异性的观测结果及其理论意义；并系统介绍了ＣＢＲ各向异性形成的各种机制；展望了下一代宇宙微波背景探测器（ＭＡＰ和ＰＬＡＮＣＫ）的科学目标和主要技术参数。
The recent progress on observation and theory of the cosmic microwave background radiation(CBR) is presented in this paper. Firstlyl the observational cosmology based on COBE satellite ispresented, including the observational results of the spectrum and anisotropy of CBR, as well asthe theoretical significance of these results. Then a variety of mechanisms on the formation of theanisotropy of CBR are described. Finally the scientific objective and major technical parametersof the next--generation detectors of CBR (MAP and PLANCK) are highlighted.
