标题： Calculation of Cosmic Background Radiation Anisotropies and Implications

摘要： 我们回顾了被认为会产生宇宙微波背景各向异性的物理过程，主要（但非唯一）关注早期宇宙中声波的影响。 我们始终试图提供直观的物理图景来阐释关键概念，并阐明预言的各向异性如何依赖于宇宙学参数（如Ω和h）。这些讲座的后半部分专门讨论了微波背景数据分析技术，重点放在对COBE DMR数据的分析上。 特别是，详细描述了数据压缩的Karhunen-Loève方法。 显示英文摘要

摘要： We review the physical processes that are thought to produce anisotropy in the cosmic microwave background, focusing primarily (but not exclusively) on the effects of acoustic waves in the early Universe. We attempt throughout to supply an intuitive, physical picture of the key ideas and to elucidate the ways in which the predicted anisotropy depends on cosmological parameters such as Omega and h. The second half of these lectures is devoted to a discussion of microwave background data analysis techniques, with an emphasis on the analysis of the COBE DMR data. In particular, the Karhunen-Loeve method of data compression is described in detail.
