摘要： In this paper,we use the stepped reduction method suggested by Yeh Kai-yuan in 1965 to obtain the general oslution of steady heat conduction of a disc with nonhomogeneity and variable thickness. Through an illustrative example,the error of Yeh's method is analysed. The result shows that it is effective for solving ordinary differential equation with variable coefficients.

关键词: free convection, MHD, finite difference method, heat and mass transfer
