【Abstract】 With the Yangbajing AS γ array, the time variation of 10TeV cosmic ray was studied. Solar time semi diurnal and diurnal variations have been detected with 10 4 σ and 9 6 σ levels for the 10TeV cosmic ray flux and semi diurnal variation with an amplitude 0 13% and a phase 0.2 and diurnal variation with 0 075% and 0 12. The sidereal diurnal variation for 10TeV cosmic ray was not found with 0 7 σ level. The analysis result in longer period gives some evidence of 7 days variations.更多还原
