| 英文摘要 | PSR B2111+46 is studied and analyzed by the method of Gaussian fit separation of the average profile (GFSAP). It has been observed at six frequencies, 408, 610, 925, 1408, 1640, and 4850 MHz, serving as an excellent sample for a multifrequency analysis. Applying the GFSAP method we find that PSR B2111+46 has five components in its profile at all six frequencies. The result supports Rankin's "core-double cone" model in emission region. On the basis of component decomposition, we discuss the geometrical structure of core, inner cone and outer cone, the emission beam radius, the emission region altitude and the geometry symmetry. We also examine the spectrum characteristics of core, inner cone and outer cone. It is found that the spectrum of the core is steeper than the inner and outer cone. |
