摘　　要：针对辐射直接交换面积,分别用数论网格法与Monte-Carlo法进行了比较计算。结果表明,与Monte-Carlo法相比,数论网格法具有计算速度快,计算精度高及使用方便等优点。Number theory net points method is applied to compute the radiant direct-exchange areas in long furnace model. By using the number theory net points optimum coefficients instead of multiple integration, three kinds of zone-pairs direct-exchange areas ars computed. A comparison between this method and Monte Carlo is made. The speed, accuracy, and their unique characteristics are discussed in order to determine which is an optimal method for computing radiant direct exchange areas.
