摘要：

Fast Radio Bursts (FRBs) are milliseconds-duration radio bursts primarily originating from cosmological distances. Observations indicate that FRBs exhibit high levels of polarization. The polarization properties carry vital information regarding the radiation mechanisms and environmental characteristics of FRB sources. In this talk, I will discuss two primary questions related to the physical mechanisms of FRBs using observational results. Topics include "Where is the radiation region of FRBs?" and "How are FRBs produced through possible coherent radiation mechanisms?". I will provide arguments suggesting that FRBs likely originate from magnetar magnetospheres and explore the production and propagation of FRBs. Additionally, I will examine the advantages and disadvantages of close-in (Pulsar-like) and far-away (GRB-like) radiation models based on observational data.
