| 摘 要： | 四维空间超曲面等投影问题用几何方法是不便表达或不易表达的，但用抽象的数学解析的方法可方便而准确的描述。本文用解析方法确定四维空间中投影的五个问题，不仅为计算机绘制四维空间投影图提供大量的数学模型，也为几何作图提供了依据。

| Abstract: | Projective problems of projection concerning hypersurfaces in 4-D space are not easily represented by geometrical method. But they can be conveniently and exactly described by abstract mathematical analysis. This paper deals with five problems of projection in 4-D space, using analytical method. It provides not only a number of mathematical models for plotting projective views in 4-D space with the aid of computer but also gives the base for geometrical construction. |
