  1. Numerical results are obtained for velocity, temperature and concentration profiles, variations of both nusselt and sherwood numbers under different buoyancy ratio and inclination angles of = 15 - 90. at a given inclination angle, heat and mass transfer rates decrease with heat and mass buoyancies and the buoyancy ratio b decrease from high positive values, and then increase again with the buoyancy radio b further decreasing after the velocity and transfer rates reaching a minimum

    研究結果表明：傾斜角度一定，當熱浮力與物質擴散浮力共存且二浮力之比b從較高正值變化到較高負值時，流體速度和熱質傳遞速度從高逐漸變低並出現最小值，此後隨著向下浮力的增大，流體向下流動且隨| b |的增大而加速，熱質傳遞速率隨| b |的增大而重新增大。
