| 英文摘要 | We report on high-sensitivity polarization measurements of the rotating radio transient (RRAT) J2325-0530 conducted with the Five-hundred-meter Aperture Spherical radio Telescope. Using single-pulse search techniques and full-Stokes parameter analysis, we comprehensively explore the source's emission characteristics. The observations reveal three distinct pulse profile types-single-peaked, double-peaked, and multi-peaked-with the multi-peaked category displaying prominent polarization reversals (mean linear polarization fraction of 27.5% +/- 0.3%) and broader pulse widths ( 7.degrees 50 +/- 0.degrees 82 ). The relative pulse energy distribution follows a power-law trend and exhibits a strong positive correlation with pulse width (r = 0.80). Through analysis of orthogonal polarization mode transitions, we suggest that the emission likely results from the interplay of multi-scale magnetospheric processes in the polar cap region. Future multi-wavelength campaigns could further test the distinctiveness of this source's emission mechanism. Overall, our findings enhance the current understanding of RRATs' complex emission behavior and inform the broader study of pulsar magnetospheric dynamics. |
