摘要
Using a new method of multi-frequency of K parameter,we estimate the ratio of altitudes of radio emission region of pulsars at 430 and 1418 MHz.The value of the ratio is 1.34±0.12 and the power law index of altitude-frequency is 0.24±0.08.It is indicated that the lower radio frequencies originate further out and the emission region is radially narrow.
