中文摘要：

根据宇宙大爆炸理论的预言,宇宙经历了由暴涨阶段到辐射阶段到物质阶段再到如今的加速膨胀阶段.在辐射阶段所残留的退耦的自由光子便形成了现在人们所观测到的宇宙微波背景辐射.如果没有扰动,微波背景辐射将是各向同性的,但是在宇宙形成的初期存在各种各样的扰动,因此宇宙微波背景辐射呈现各向异性.针对由遗迹引力波对微波背景辐射极化所产生的各向异性的影响,重点讨论电场型极化和磁场型极化.

英文摘要：

According to the prediction of the theory of Big Bang, the universe has gone through from the phase of inflation to the phase of radiation and to the phase of matter at last to the phase of acceleration expansion now. In the radiation phase, the rudimental free photons of decoupling become the Cosmologic Microwave Background Radiation which we observe by now. If there is not any perturbation, the CMB radiation will be isotropy, but in the earlier era of the universe, there exist all kinds of the perturbations, which caused the anisotropy the Cosmic Microwave Background radiation. This research will emphatic depict the influence of the relic gravitational wave for the Cosmic Microwave Background radiation in anisotropy of polarization, especially in E-mode and B-mode polarization.
