双星星星反射效应理论的几何和辐射加热问题是根据等位面发展起来的，并具有足够的一般性，以便包括偏心轨道和非同步（甚至是离心限制）旋转，并处理多次反射。必要的物理，数学和逻辑，然后提出和计算组织，使一个给定的量计算只需要经常，强调局部表面的数量和方面相关的数量之间的区别。根据需要重新计算的频率，将局部几何量、测辐射热量和波长特定量分组存储。一些测试的计算机程序的基础上，这种反射模型给出的形式的图形中，程序结果进行比较，一个特殊的确切的情况下，从早期的程序的结果。新程序为所有测试提供了直观合理的输出，测试给出了旧程序的准确性，采用新程序的详细反射计算作为比较的标准。给出了一个表，它显示了收敛的多次反射计算的表面有效温度的恒定分布。参考文献11篇。
The geometric and irradiation heating problems for the binary star reflection effect theory are developed in terms of equipotential level surfaces and are sufficiently general so as to include eccentric orbits and nonsynchronous (even centrifugally limited) rotation and to treat multiple reflection. The requisite physics, mathematics, and logic are then presented and the computations are organized so that a given quantity is computed only as often as necessary, emphasizing the distinction between local surface quantities and aspect-related quantities. The local geometric, bolometric, and wavelength-specific quantities are grouped for storage according to how often they need to be recomputed. Some tests of a computer program based on this reflection model are given in the form of graphs in which program results are compared to a special exact case, and with results from an earlier program. The new program gives intuitively reasonable output for all tests, and the tests give an idea of how accurate the old program is, adopting the detailed reflection computations of the new program as a standard for comparison. A table is given which shows the convergence of the multiple reflection computations to a constant distribution of surface effective temperature. 11 refs.
