摘　　要：对于利用铁乳胶室观测宇宙线强子的探测几率进行了计算。计算中对乳胶室的结构和事例的选择标准等做了考虑。给出并讨论了强子探测几率与强子在大气和在铁中的衰减长度的依赖关系及强子探测几率与入射天顶角的关系。Monte Carlo calculations of detection probability of cosmic-ray hadrons observed with Fe emulsion chambers have been carried out.The config- uration of the emulsion chamber and the selection criteria of events are taken into account The dependence of hadron detection probability on the attenuation lengths of hadrons in air and in iron is given,The relation between hadron detection probability and incident zertith angle is also presented.A brief discussion is made.
