标题： Polarization of Microwave Background: Statistical and Physical Properties

摘要： 我们讨论宇宙微波背景极化的统计和物理性质，既在傅里叶空间也在实空间中。后者有助于更直观地理解一些几何特征。我们给出了将实空间中的电性和磁性极化与测量的斯托克斯参数相关联的表达式，并讨论了如何局部构建它们。我们讨论了产生极化的必要条件，并为一些典型模型提供了模拟图和相关函数。 显示英文摘要

摘要： We discuss statistical and physical properties of cosmic microwave background polarization, both in Fourier and in real space. The latter allows for a more intuitive understanding of some of the geometric signatures. We present expressions that relate electric and magnetic type of polarization to the measured Stokes parameters in real space and discuss how can be constructed locally. We discuss necessary conditions to create polarization and present simulated maps and correlation functions for some typical models.
