In this article, the activities of tearing modes was analyzed when the plasma in Tokamak has a flowing velocity. The analysis and numerical calculation indicate, the total flowing of the plasma (equiylent to a. plasma with a rotational frequency) does not influence the activities of tearing modes, only causes the rotation of the magnetic island with a frequency equal to the rotational frequency, of the plasma, The applied helical magnetic field can suppress the rotation of the plasma effectively in the tearing layer. The role of stabilization of the helical magnetic field on the tearing modes is not affected by the plasma rotation.
