【摘要】 对二阶假想面法辐射传热数值计算模型的基本原理和数学过程进行了全面的分析。通过计算实例与原假想面法（一阶假想面法）、经典区域法相比较，证明了二阶假想面法的计算精度较之原假想面法有很大程度的提高。更多还原

【Abstract】 The fundamental and mathematical procedure of the second order imaginary plane(SIP) method for calculating radiative heat transfer is analyzed.In comparison with the first order imaginary plane(FIP) method and the zone method,the computational accuracy of the SIP method is much higher than that of the FIP method.更多还原
