摘要
预给二面角的单形在Ｅ~ｎ中的嵌入问题同杨路、张景中近期解决［２］。本文给出了预给二面角的单形嵌入Ｅ~ｎ的另一个充分必要条件，并利用这个充分必要条件，给出了构造预给二面角的单形的具体步骤。
The problem for embedding a simplex with prescribed dihedral angles in E￣n was solved by Yang Lu and Zhang Jing-zhong. In this paper. we give another sufficient and necessary condition for embedding a simplex with prescribed dihedral anglesinE￣n. And applying it, we give the steps for constructting a simplex with prescribed dihedral angles.
