 In this paper, we first present the solution to the numerical value of λE-A equivalent standard form, i.e. characteristic matrix of A in 3,4 grade matrix; and then with the help of compound matrix, We describle the index of λ-a in D k(A(λ)) and therefore introduce the outline of the solution to the numerical value of A(λ) equivalent standard form at the most time. 本文首先给出了3、4阶方阵A的特征矩阵λE－A的等价标准形的数值解法，其次借助于复合矩阵刻划了λ－a在Dk（A（λ））中的指数，从而给出了一般情况下A（λ）的等价标准形的数值解法框架 短句来源 e. characteristic matrix of A in 3,4 grade matrix; and then with the help of compound matrix,We describle the index of λ-a in D_k(A(λ))and therefore in- troduce the outline of the solution to the numerical value of A(λ)equivalent standard form at the most time. 本文首先给出了3、4阶方阵 A 的特征矩阵λE—A的等价标准形的数值解法,其次借助于复合矩阵刻划了λ—a在 D_k(A(λ))中的指数,从而给出了一般情况下A(λ)的等价标准形的数值解法框架。 短句来源 (4) ascertaining the weight of each level of evaluation index by improved level analysis way and Delphi way, getting the membership grade matrix of evaluation index by barycenter theory, and in the end proving the feasibility of the evaluation way by instance. (4) 利用改进的层次分析法和德尔菲法确定了评价指标各层次的权重,用“重心法”原理得到了评价指标各层次的隶属度向量,最后通过实例验证了该评价方法的可行性。 短句来源 The main idea of the new method is that the ralational grades of the gray system theory are taken as the similarity statistics between samples or their indexes. hased On the relational grade matrix, the samples or their indexes are clustered by the traditional cluster principles. 该方法的实质是以灰色系统理论中的关联度作为样品（或指标）间的相似性统计量，并据此按传统的聚合归类原则来实现样品（或指标）的聚类。 短句来源 Baeed on the concept of similar-and-different anti-connection grade in the Set Pair Analysis this paper presents the concepts of similar-and-different anti-connection grade matrix and its difference matrix,and then the mothod for evalnation and optimal selection of decision plan is given. 在集对分析中同异反联系度概念的基础上，提出了同异反联系度矩阵的概念和同异反联系度矩阵的差异矩阵的概念，并以此给出了决策方案评价与优选的方法。 短句来源 更多
