摘要

大量射电脉冲星的偏振观测－包括线偏振和圆偏振，个别脉冲的垂直偏振模式，累积脉冲的消偏振现象等－为辐射区的物理状态和辐射过程提供了非常确切的观测事实。但现有理论对众多观测事实尚无法给出完整的说明。综述了脉冲星的偏振观测特征，并利用逆康普顿散射模型对这些特性进行了解释。

Abstract

Polarization observations of radio pulsars, such as linear and circular polarization, polarization position angle jumps of individual and integrated pulses, can be used to get abundant information, which is very important to understanding the physical processes in the emission regions. In this paper, some basic properties of polarization observations of radio pulsars and their theoretical explanation in the Inverse Compton Scattering (ICS) model are briefly reviewed.

Key words	pulsars － polarization － radiation mechanism
