Based on a systematic investigation on the predatory natural enemy community in cotton fields to the north of the huaihe river of anhui province, the methods of polar ordination ( po ) and fuzzy cluster analysis ( fca ) were employed to study the dynamic classification of predatory natural enemy community in cotton fields and the method of principal component analysis ( pca ) was employed to study the major stages of change of predatory enemy community in cotton fields during the process of cotton growth and development 摘要在对安徽省淮北棉田捕食性天敌群落进行系统调查的基础上,采用极点排序和模糊聚类分析方法,研究了棉田捕食性天敌群落的动态分类;采用主成分分析方法,研究了棉田捕食性天敌群落在棉花生长发育过程中演变的主要阶段。
This paper mainly analyses the function level of enterprise's e-commerce in agriculture based on the website of agriculture . firstly, analyses the basic actuality of corporation websites in agriculture . evaluates the ability of enterprise in fulfilling electronic commerce by means of fuzzy set theory, including the fuzzy cluster analysis and the fuzzy pattern discernment 首先分析了国内农业企业网站的基本现状,然后引入模糊数学中的模糊聚类分析方法和模糊模式识别方法来对当前农业企业网站发挥电子商务作用的能力进行分析,以此得出了目前农业企业网站电子商务功能水平的一个基本概况。
Abstract : based on the principles of grey relative degree c alculation and fuzzy cluster analysis, the paper presents a method of dynamic an alysis through time series of dam observation data to reveal the difference betw een observation points in the dam deformation . this provides foundamental meteri al for study and analysis of the dam condition and safety supervisor 文摘:基于灰色关联度计算和模糊聚类分析原理,对大坝时间序列观测数据进行了动态分析,以揭示大坝变形观测中各观测点间的变形性态分类差异,为进一步分析和研究大坝的工作性态和安全监控提供基础分析资料
The partly gas stratum produce the water in the past logging interpretation method ca n't distinguish them easily . according to the logging and brothel logging shows and testing results, this thesis will utilize the cross-plot analysis technology to look for the qualification and quantity index of the containing water and gas by mutual comparison, triumphantly discern the containing gas and water quality in the store stratum; using b-p network can recognize the reservoir; the utilize the fuzzy cluster analysis technology to cluster analyze separately the water well section and water quality well in the store stratum, settle the type datum and central type distinctly and analyze fluidity's material quality and diversity in all models and others store stratum, triumphantly distinguish the diversity of the containing water and gas 本次论文以钻井录井显示和测试结果为依据,利用交会图分析技术,相互对比寻找出区分含水与含气的定性与定量指标,成功地对储层含气、水性质进行了识别;利用bp网络分析识别储层类型,利用模糊聚类分析技术,将测试产水井段与产水井段数据分别作聚类分析,确定出各自的类数和类中心,建立起聚类模型,将所建模型对其它储层段进行含流体性质及差异分析,成功地对含气性差异进行了判别。
Fuzzy relation theory is one of the most important branches of fuzzy mathematics and is extensively used in many fields especially in the area of decision-making . for example, fuzzy clustering analysis, choice problem under fuzzy preferences, ordering of fuzzy quantities and fuzzy preference structures are all based on fuzzy relations 模糊关系是模糊理论最重要的内容之一,其应用十分广泛;尤其是在模糊决策的许多领域中,如模糊聚类分析、模糊选择、模糊量排序、模糊偏好结构等,其研究都是建立在模糊关系基础之上的。
According to the viewpoint of prof . f . h . wittmann and the development trend of concrete science, the author has successfully combined the theory of fuzzy cluster analysis with the quality control work of rmc production by mathematical modeling, hi actual work, there are some differences of concrete mix proportion and concrete performance index between the standard sample that is accord with all demands of hpc and differential sample that is mainly accord with demands of mix design by comparing and clustering . therefore, rmc is up to the standard of hpc after adjusting these differences 本文正是基于上述指导思想和混凝土材料科学的发展趋势,把模糊聚类的分析理论和混凝土质量控制工作中存在的问题,通过建立数学模型将二者有效地结合起来,其目的及意义是:在实际工作中,将基本符合设计要求的若干组混凝土配合比数据、性能指标数据,与经过工程实际检验、符合高性能混凝土各项指标要求的混凝土进行比较、归类,找出差异,调整参数,实现混凝土生产的高性能化。
