【Abstract】 The observations show that a plage is a bright active region of the hydrogen’s H_α line or C_aII’s H or K line in the spectroheliogram. The plage temperature is about a few hundred degrees higher than that of the background whick is undisturbed chromo-sphere. The problem about the plage heating had already been investigated. Osterbrock first suggested that a magnetohydrodynamies wave is a possible way to heat a plage. In this paper a plasma turbulent wave as a heating mechanism is proposed. We consider that the pondermotive force come from the Alfvén wave may heat the plage due to an increase of the thermal velocity of the particles. Assuming that a magnetic-field line is approximately described by a quadratic curve relatively consistant with an observed one and the magnetic configuration is axisymmetric, from the coupling equation of the flow-wave feild, we may derive the formula expressing the plage heated by plasma turbulence. Our result is in agreement with observations.更多还原
