  "abstract": "We determine spectral indices of 228 pulsars by using Parkes pulsar data observed at 1.4 GHz, among which 200 spectra are newly determined. The indices are distributed in the range from -4.84 to -0.46.Together with known pulsar spectra from literature, we tried to find clues to the pulsar emission process. The weak correlations between the spectral index, the spin-down energy loss rate $\\dot{E}$ and the potential drop in the polar gap $\\Delta\\Psi$ hint that emission properties are related to the particle acceleration process in a pulsar's magnetosphere.",
