辐射交换构形因子F1-2（下文简称为“因子”）定义为离开等温区域Ax入射到另一区域A2上的能量的分数。朗伯散射定律的有效性是假定的。本文讨论了两个矩形有一条公共边且成任意角度时这些系数的计算，并给出了计算值表。它示出了两个平行的，凸多边形的因素，形成一个正确的棱柱的基础，可以从矩形得到的结果。这些因素的值为一些规则的多边形制成表格。一个单独的表格给出了蜂窝结构的系数，蜂窝结构在航空和航天中应用广泛。更大的准确性在计算中的重要性比通常认为必要的是由一个例子。
The radiant-interchange configuration factor F1-2 (later referred to simply as ‘factor’) is defined as the fraction of the energy leaving an isothermal area Ax that is incident upon another area A 2. The validity of Lambert’s law of diffuse radiation is assumed. The calculation of such factors in the case of two rectangles having a common edge and forming an arbitrary angle is discussed, and a table of calculated values is presented. It is shown how the factors for two parallel, convex polygons, forming the bases of a right prism , can be derived from the results obtained for the rectangles. Values of such factors for a number of regular polygons are tabulated . A separate table gives factors for the honeycomb structure, much used in aviation and aerospace. The importance of much greater accuracy in the calculations than is generally thought necessary is shown by an example.
