Abstract：
An analysis of the performance of the Yangbajing EAS array,Tibet,has been done with the Monte Carlo simulation in this paper.Selection criteria on EAS events have been defined.The accuracy of EAS core position determination is 3.4m.The angular resolution of primary particle arrival direction is better than 1.1 degree.The energy response function of the array has been given,i.e. lg(E ₀)=lg(0.45ΣN _i)±0.226,where E ₀(TeV) is the primary energy of the incident particle,ΣN _iis the sum of detected particle number on FT detectors.
