Abstract：
According to the hadronization program ART1.0 of AMPT Monte Carlo generator, the evolution picture of hadronization process is obtained. The radii of reaction area are then calculated based on the distribution picture of hadrons in different evolution time. Comparing the results with those obtained from the HBT momentum correlation, the freeze-out time is fixed finally. The result obtained is reasonable.
