Based on random Poisson distributional model and Gutenberg-Richter law, we made 8 groups of simulated seismic catalogues with the sample size of 1 000 to 15 000 within 20 years so that we could discuss the effect on the H value of frequency sequence of seismicity caused by the calculational conditions of sample size and τmax of maximal fitting window length. The result shows that the whole precision and stability of H value improve with the sample size increasing. When τmax is equal to 300, it is specially obvious. Case calculations show that it is available to pick up well the process of anomaly change of H value before strong earthquake with selecting reasonable calculational conditions.
