摘　　要：梁王山ＥＡＳ阵有关宇宙线谱数据的重新分析表明，在６×１０１４～１０１６ｅＶ能区的初级宇宙线谱中存在膝．微分大小谱在Ｎｅ＝８．８×１０５处变陡，膝具突然特征．依据假定质子或铁核初级的模拟，转换大小谱为能谱．膝在能量中的位置对于质子为２×１０１５ｅＶ或对于铁核为３×１０１５ｅＶ．It has reanalysed data of Mt.Liangwaing EAS array concerning the cosmic ray spectrum.The results show that the existance of the Knee on the primary cosmic ray spectrum in the energy range 6×10~14—10~16eV.The steepening of the differential size spectrum slope at Ne=8.8×10~5 and the Knee has abrupt character.The conversion of the shower size spectrum to the energy spectrum by the simulations of an assumed proton or iron nuclei primary.It is found that the Knee Location in the energy of 2×10~15eV for the proton or 3×10~15eV for the iron nuclei primary.
