contents The solutions of a kind of second-order homogeneous partial differential equation are called (real kernel) alpha-harmonic functions. The alpha-harmonic functions and their first-order partial derivative functions on unit disk are estimated using the $L^p$ norm of the boundary functions of the alpha-harmonic functions. A series of inequalities are obtained. In addition, when the alpha-harmonic functions are quasiconformal, their first-order partial derivative functions are estimated by the arc length of the domain boundary and the Lipschitz constant of the boundary functions. All of the inequalities obtained in this article are optimal or asymptotically optimal.
