Abstract	Using the method of Gaussian Fit Separation of Average Profile (GF-SAP), we re-examlne the average profiles of nine pulsars at several frequencies,ranging from 408-1642 MHz. This method enables us to obtain the number of components for each pulsar, and the parameters for each component, the width, position and amplitude. The p-P relation for the inner cone and outer cone are studied separately, and the results are, respectively, ρ= P^-0.51±0.05 and ρ=P^-0.42±0.06. The results can be interpreted as a confirmation of the double-cone structure of pulsar emission beams. The altitudes of emission region, and the radius-to-frequency-map (RFM) are also examined; for the outer cone, we obtained r(v) ∝ v^-0.19±0.09.
