多面锥内外表示形式的相互转化

Mutual transformation of the internal representation and external representation of the polyhedral cone

从多面锥与极锥的关系出发，对满秩和降秩情形采用统一的处理方式，提出了多面锥内、外表示形式相互转化的构造性方法．该方法具有直观性、可操作性等特点，并给出了相应的几何解释及算例．

From the relation between the polyhedral cone and its polarform, the mutual transformation of the internal representation and external representation of the polyhedral cone are presented by a unified approach and construction method, which is characterized by concreteness and operability. Clear geometric explanation and several examples are given.
