| 摘 要： | 针对目前所提出的各种离散坐标格式中的离散方向大都是固定的，不能任意调节，因而无法满足一些工程辐射问题的需要的问题，在“带无穷小加权离散坐标格式”的基础上，提出了一种离散坐标方法来计算任意方向上的辐射强度．同时，提出了带微小控制角有限体积法的概念．

| Abstract: | In the existing discrete ordinate shcemes reported in the literature, the discrete directions are fixed up, and cannot be arbitrarily adjusted; therefore these schemes can not used to solve some radiation problems in which it is necessary to calculate the radiation intensities is specified directions. On the basis of the Discrete Ordinate Scheme with (an) Infinitely Small Weight(s), a new discrete ordinate algorithm is proposed to solve this class of radiation problems. Finally, a new concept, named the finite volume method with infinitely small control-angles, is proposed. |
