中文摘要：

用AMPT蒙特卡罗产生器中的强子化程序模块ART1．0，得到了强子化过程的演化图形，并基于强子在不同时刻的空间分布图，估算出了不同时刻的反应区域半径．将所得结果与根据HBT关联得到的结果相比较，定出了冻结为强子气体的时刻，得到了合理的结果。

英文摘要：

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.
