在国际数学奥林匹克试题中,有些几何题推广到空间,思考起来是比较复杂的.本文介绍的体积坐标,建立了四面体内点与四元数组在一定条件下的对应,具有一些特殊的性质.
In the International Mathematical Olympiad test questions, some geometric problems are generalized to the space and the thinking is complex. The volume coordinates introduced in this paper establish the correspondence between the four-sided in-vivo points and the quaternion array under certain conditions and have some special properties.
