Several prevalent methods for block - segmentation in a web page are introduced , and then it is validated that the method for chinese web - page classification based on block importance is better than the one for traditional methods 介绍了几种流行的网页分块技术，并通过实验验证了基于分块重要度的主题网页分类法的分类质量优于传统的主题网页分类法。
Based on the kano model analysis , a formula to calculate the importance rating of achieving the improvement increment of competitive seating arrangement was presented , and then the correct factors of the fundamental importance ratings were determined 基于卡诺模型的分析，提出了实现顾客需求竞争位次改进增量的重要性计算公式，进而确定了基本重要度的修正因子。
Then , the optimal ordering permutation for the basic events of fault tree was produced by structural importance and neural network methods respectively , and the resulting size problem of bdd affected by the basic events " order was solved 其次，用基于结构重要度和基于神经网络两种方法实现了底事件最优指标顺序的确定，解决了底事件指标顺序对bdd规模的影响问题。
3 . it is pointed out that organization structure and employee size influence the awareness of the value of the factors to environment a little , while field of industry and size of registered capital influence more apparently 对于各环境因素对高技术企业创立的影响程度，企业性质、员工规模对影响因素重要度的认知影响较小，经营领域和注册资金规模对影响因素重要度的认知影响较大。
In this strategy , the theory and methods of attribute importance within rough set were applied to define the weight of each feature attribute of the case ; the theory and methods of knowledge reduction was applied to define the index of the case knowledge base 在该策略中，运用粗糙集中属性重要度的理论和方法，确定事例各特征属性的权重，运用知识约简的理论和方法判断事例知识库的索引。
This article proposes the objective way of calculating the importance of each attribute based on rough set to get the weight of each indicator and unify these two methods above to finally determine the target weight 本文将粗集理论中属性重要度的概念引入网络课程评价中的权重确定过程，提出将决策者先验知识给定的权重同粗集理论确定的属性重要度结合起来作为最终确定网络课程评价指标权重的方法。
Based on the background of the urban - rural integration development in china and the limitation of the traditional region highway network planning theories , this paper combines the theory for the node important degree and area location into a new system 摘要本文基于中国城乡一体化发展的大背景和目前公路网规划理论和方法的局限性，提出了将节点重要度法与区位论融为一个系统的公路网规划的布局方法。
The programming result shows that the algorithm , which is used in the freeway planning and evaluation for zhanjiang city , is effective and credible , and that the layout method based on the important degree of nodes is good enough to be applied widely 规划结果表明所研究的方法在湛江市高速公路规划评价系统中是可行的，总量控制法中确定路网布局的“重要度布局法”是一种较好的方法，值得进一步推广应用。
This paper describes a method in environmental risk assessment ( era ) - fault tree analysis ( fta ) , and applies it to an oil - fuel depot at sheshan township of nanjing city , in close vicinity of the yangtze river 摘要将故障树分析法应用于南京摄山油库火灾爆炸事故的环境风险评价，构建了油库火灾爆炸故障树，确定最小割集，进行结构重要度分析，计算汽油罐发生火灾爆炸的概率，并对各基本事件的概率重要度进行了分析。
We study the reliability prediction and allocation methods and do the prediction and allocation . with respect to two different importance concepts , importance analysis is presented respectively . we rank modules according to importance and find out the weak spots of sg - iii 根据概率重要度和关键重要度两种不同的重要度定义,对神光iii装置进行重要度分析,对组件的重要度进行了排序,找出了系统的薄弱环节。
