标题： Primordial Gravitational Waves and Cosmic Microwave Background Radiation

摘要： 这是2009年7月在巴黎召开的第12届Marcel Grossmann会议“原初引力波与宇宙微波背景”平行分会的报告摘要。报告和讨论展示了理论和观测方面取得的重要进展。现有的数据显示出宇宙微波背景各向异性中存在引力波贡献的一些迹象，而正在进行和计划中的观测工作有望将这些迹象转化为关于实际探测的更确信的陈述。 显示英文摘要

摘要： This is a summary of presentations delivered at the OC1 parallel session "Primordial Gravitational Waves and the CMB" of the 12th Marcel Grossmann meeting in Paris, July 2009. The reports and discussions demonstrated significant progress that was achieved in theory and observations. It appears that the existing data provide some indications of the presence of gravitational wave contribution to the CMB anisotropies, while ongoing and planned observational efforts are likely to convert these indications into more confident statements about the actual detection.
