我们提出了一个分析的μ子事件与所有μ子的多重性收集在21804小时的第一个大体积探测器塔的操作。测量的μ介子强度角分布已转换成3 - 12 km深度范围内的“深度-垂直-强度”关系。对这个关系的分析使我们能够推导出初级全核子谱的功率指数γ：γ = 2.78 +/- 0.05。将“深度-垂向-强度”关系转换为标准岩石，并与其他实验数据进行了比较。我们还提出了推导出的垂直μ子谱在海平面。[S0556-2821（98）00517-7]。
We present an analysis of muon events with all muon multiplicities collected during 21804 h of operation of the first Large Volume Detector tower. The measured angular distribution of muon intensity has been converted to the "depth-vertical-intensity" relation in the depth range from 3 to 12 km w.e. The analysis of this relation allowed us to derive the power index gamma of the primary all-nucleon spectrum: gamma = 2.78 +/- 0.05. The "depth-vertical-intensity" relation has been converted to standard rock and the comparison with the data of other experiments has been done. We also present the derived vertical muon spectrum at sea level. [S0556-2821(98)00517-7].
