英文摘要	Within the framework of Polyakov-Nambu-Jona-Lasinio model and by means of Multiple Reflection Expansion, we study the finite volume effects on chiral phase transition, especially its influence on the location of the possible critical end point (CEP) and masses of mesons. Our result shows that as the radius of the sphere decreases, the location of CEP shifts toward smaller temperature while remains almost a constant in chemical potential. As for the finite volume effects on the masses of mesons, the masses of pi and Kincrease with decreasing volume, while for sigma, eta and eta' the situation is the opposite. Especially, the masses of chiral parters pi and sigma get closer as the volume decreases, indicating that the dynamical chiral symmetry breaking effect reduces with decreasing volume.
