Abstract：
This paper studies deeply trigger decision criterion of the PHOS in ALICE experiment by simulation, including three parts: 1) the energy reconstruction performance of PHOS is tested; 2) the selection of trigger threshold is analyzed and the trigger efficiency is calculated; 3) the trigger rate of PHOS is evaluated and its selection is discussed for the different collision mode.
