讨论了宇宙微波背景极化在傅里叶和实空间中的统计和物理性质。后者允许更直观地理解一些几何特征。我们给出了电极化和磁极化类型与实空间中测量的Stokes参数的关系表达式，并讨论了如何在局部构造。讨论了产生极化的必要条件，并给出了一些典型模型的模拟图和相关函数。
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.
