| 摘 要： | 1 Introduction “Spatial Angles Calculations” means that all the calculations of given and unknown parameters are related to calculating angles in 3D space. The functions and relevant parameters in 3D space are much more complicated than that in 2D space, i.e. on a plane. Professor Sun, based on his research conducting for more than a decade, presented a series of new algorithms to calculate angles in space which are valuable in both theory and applications1]. The authors found that, in g…

| Abstract: | Aiming at the specific cases existing in spatial angles calculation the paper investigates five types of them: lines in specific orientations, planes in specific orientations, two lines defining a plane and angles between them, orientations and relevant parameters of a line lying on a plane, and orientations and relevant parameters of a plane passing through a line. The results are presented. The strategy presented provides a firm theoretic basis for the application of the new method of spatial angles calculations. |
