摘　　要：联系加热炉几何模型,在推导、阐述数论网格求积方法应用于直接交换面积计算的同时,比较了其与高斯方法计算直接交换面积在计算精度及计算机耗时等方面的优越性。结果表明,数论网格法更简单、准确和节省机时。An integration technique using number-mesh method based on number theory is derived and stated in detail so as to apply it to the computatison of radiative direct-exchange areas that needed for zonal analysis. Such advantages as higher accuracy and time-saving on computer are thus attainable in comparison with using Gaussian quadrature method to compute radiative direct-exchange areas. The results show that this technique is simpler,more accurate and time-saving than other methods previously used.
