用三火球模型分析了核-核以AGS(the Alternating Gradient Synchrotron)和SPS(the Super Proton Synchrotron)能量碰撞中产生质子的快度分布．Monte Carlo方法计算的结果分别与金-金以6,8和10．8AGeV的能量并以不同中心性碰撞、铅-铅以158AGeV／c的动量碰撞、以及硫-硫以 200AGeV／c的动量碰撞的实验数据符合．
A three fireball model was used to analyze the velocity distribution of proton generated by energy collisions between nuclear-nucleus and AGS (the Alternating Gradient Synchrotron) and SPS (the Super Proton Synchrotron). The Monte Carlo results show that the collision of Au-Au with energies of 6, 8 and 10.8 AGeV with different central collisions, Pb-Pb collisions with 158AGeV / c momentum and Sulfur-sulfur collision with momentum of 200AGeV / c The experimental data match.
