给出了大范围空气簇射的蒙特卡罗模拟结果，以显示不同高度强子组分含量的差异，目的是为棱镜实验选择最佳高度。用CORSIKA程序用QGSJET和GHEISHA模型模拟EAS，计算了绕EAS轴半径50m的圆内到达观测层的强子数。然后利用两个强子分量之间的经验关系计算了强子分量产生的中子数。我们用ProtoPrISMA阵列在海平面上对结果进行了检验，并记录了与模拟结果一致的中子。
The results of Monte-Carlo simulations of extensive air showers are presented to show the difference of the hadronic component content at various altitudes with the aim to choose an optimal altitude for a PRISMA-like experiment. The CORSIKA program for EAS simulations with QGSJET and GHEISHA models was used to calculate the number of hadrons reaching the observational level inside a circle of 50 m radius around the EAS axis. Then the number of neutrons produced by the hadronic component was calculated using an empirical relationship between the two components. We have tested the results with the ProtoPRISMA array at sea level, and recorded the neutrons which are consistent with the simulation results.
