The characteristic of combined heat and mass transfer by natural convection has been the focus of researches for a long time . numerical analysis is conducted for combined heat transfer and mass transfer by natural convection on inclined surface . effects of the inclination angle and the ratio of buoyancies due to heat diffusion and mass diffusion on fluid flow and heat and mass transfer characteristics have been investigated for pr = 0 . 7 and sc = 0 . 05 - 5 . 0 本文采用数值计算方法研究了倾斜平面上的传热传质复合自然对流，求解了动量、能量及质量的完整方程，考察了热质扩散共存时倾斜平面上的流动和传热特性，着重分析了热浮力及物质扩散浮力之比b和倾斜角度对流体流动和传热传质特性的影响。
