该阵列还对宇宙射线在1015-1016 eV的all»partie1e光谱的“膝盖”周围引发的空气阵雨具有高灵敏度，能量估计具有相当小的模糊性。我们得到了膝盖区域3 × 10”和2 × 10’6 eV之间的原始宇宙射线的微分能谱，所得的总能谱不像单一的幂律，在能量约为1015”25 eV时，斜率逐渐变陡。光谱表示为J (E0): 1.5 × 10 2”（EU/101175 e\”）“2’600’04 （in’s’lsrfl eV”），E0< 10’75 eV
The Tibet array is the first air shower detector to search for 10 TeV gamma—ray point sources. This array also has a high sensitivity to air showers initiated by cosmic rays around the" knee" of the all» partie1e spectrum at 1015-1016 eV, with quite small ambiguity for the energy estimation. since the development, of air showers in this high—energy r'egioii, is (lose to maximum at Yangbajing altitude (4300 m above sea level), Using the data set taken with the Tibet, array in the period from 1990 October through 1993 July. we obtained the differential energy spectrum of primary cosmic rays between 3 X 10” and 2 x 10'6 eV eovering the knee region The Overall spectrum obtained does not resemble a single pOWer law and shows a gradual steepening of the slope at energies around 1015" 25 eV. The spectrum is expressed as J (E0): 1.5 x 10 2 “(EU/101175 e\")" 2'60i0'04 (in"" s’ lsrfl eV”) at E0< 10” 75 eV
