Abstract: We summarized the basic processing steps of pulsar timing model correction.The calculating methods of Einstein,Shapiro,Roemer,dispersion delay,and the the binary pulsar models in common use were given.Order of timing delay correction magnitudes were calculated using milisecond binary pulsar data.The pulsar was called J0437-4715.The data Is provided by Australia Telescope National Facility.The influence of calculating results using different binary pulsar models and planetary ephemeris were analyzed.
