摘要: 分析了变胞机构在变胞过程中构件数目减少的情况,将其分为构件脱离机构以及构件合并的两种情形。讨论了构件数目减少但构件间邻接关系未转移的情况,并给出了相应情况下的邻接矩阵描述方法。通过实例验证,使用提出的邻接矩阵对构件脱离机构情况的分析是正确的。

Abstract: The reduction in the number of components of metamorphic mechanisms during configuration transformations was analyzed and classified into two cases: components being separated from the mechanism and components being combined.A situation of reduction in numbers of components was discussed in which adjacency is not transformed.A description method of adjacency matrix based on the situation was presented.Correctness of the method was proved by an example.
