For example, Keyfitz made the classification of the bifurcations in one state variable, without symmetry up to codimension 7; Golubitsky and Schaeffer obtained the classification of the bifurcation problems in one state variable with Z_2 symmetry, in one parameter up to codimension 3; Golubitsky and Roberts studied the classification of degenerate Hopf bifurcation in two state variables with dihedron D_4 symmetry, in one parameter up to topological codimension 2; Melbourne obtained the classification of bifurcations in three state variables with octahedral symmetry, in one parameter, up to

需要指出的是以上研究均没有考虑分歧参数的对称性，Futer，Sitta和Stewart的工作虽然考虑了分歧参数的对称性，但仅限于分歧参数与状态变量具有相同的对称性，他们得到了状态变量与分歧参数均关于二面体群D_4对称，拓扑余维数不大于1的分歧问题的分类。高守平和李养成则讨论状态变量和分歧参数均具有对称性且对称性可以不同的分歧问题，并给出了状态(来源：A770707BC论文网www.abclunwen.com)变量关于二面体群D_4对称，分歧参数关于S~1对称，拓扑余维不超过1的分歧问题的分类。本文第一章讨论两个状态变量关于二面体群D_3对称，两个分歧参数关于O(2)对称的分歧问题，给出了该类分歧问题在非退化条件q(0)≠0下所有情形的分类与相应的识别条来源：AdadaBC论文网www.abclunwen.com

It is necessary to find a new method for garbage disposal. Compared to existent methods, landfill method of garbage block has its characters, which includes classification throwing, collection and predispose of garbage that make garbage disposal classification; use of reclaimable street collection that make garbage disposal resource; shatter,dehydration and press packing of garbage street collection that make garbage disposal decrease; disinfection and classification stack that attribute to classification administer and supervise of garbage field and make garbage disposal harmlessness; recycle, compost, burning and landfill that make garbage disposal synthesis; exploitation and use of garbage field that make garbage disposal environmental protection.

与已有的垃圾处理方法比较，垃圾块体填埋法有自己的特点，以社区为单元的垃圾源头分类投放、收集和预处理，能使垃圾实现分类化处理；通过垃圾中可回收废物的回收利用，能使垃圾最大限度资源化；通过垃圾分类粉碎、脱水、压缩成块体，使垃圾有效地减量化；经过消毒、分类堆砌有助于垃圾填埋场地的分类管理和安全监控，使垃圾处理基本无害化；回收、堆肥、焚烧、填埋，使垃圾处理综合化；填埋场的复垦与开发利用，使垃圾处理环保化。

Among them, the Center for Biological Science Book Collecting 46,"Chinese Library Classification"(hereinafter referred to as "CLC") classification; Collecting books for the Library of 268 species,"the Chinese Academy of Sciences Library Classification"(hereinafter referred to as "Section Method ") classification.

The use of rock geomechanics classification method to increase the tiger to the right tunnel surrounding rock classification, the reference and evaluation criteria while rock classification method and the BQ were varied, but the same number of factors can be integrated indicators of scientific objective of rock classification for the tunnel to provide an important basis for the design and construction.

利用岩体地质力学分类方法对老虎岭隧道右幅进行围岩分类，其参考因素和评价标准虽然与BQ围岩分级方法不尽相同，但同样能够综合多因素综合指标，对围岩进行科学客观的分类，为隧道的设计施工提供重要依据。

It is concluded that, first, geochemical data of the surface soils can clearly distinguish two kind of soils, that is, juvenile soils, for example, purple soils, which inherits most geochemical characteristics of the parent rocks or materials, and anthropic soils, the geochemical characteristics of which have been greatly changed as the results of intensive impact from variety of agricultural uses. Second, different soils have typical indicator elements association respectively due to different parent rocks or materials and utilization, such as purple soils, yellow soils (low alkali and alkaline-earth metal contents and pH value), paddy soils (high organic element and heavy metal elements contents) and fluvo-aquic soils (high rock-forming accessory mineral elements contents) and so on. Consequently, it can be suggested that elements association is an important indicator for two key factors (parent materials and anthropic activities) of soil classification. Third, some differences exist between soil genesic classification and result of cluster analysis, because geochemical characteristics of surface soils can not completely represent the foundation applying to soil genesic classification, that is, condition and process of soil-forming, and soil property.

结果表明：浅层土壤的地球化学数据能较好地用来区分两类土壤，即紫色土一类的幼年土壤（在很大程度上继承了母岩、母质的地球化学特征）和受强烈人为活动水耕、早耕熟化的土壤（外来物质的不断加人显著地改变了浅层土壤原有的地球化学性质）；(2)各类土壤因母岩母质和利用方式不同，各具明显的标志性元素组合特征，如紫色土、黄壤（低碱和碱土金属元素和pH值）、水稻土（高有机元素、肥料元素和重金属元素）和潮土等，因此，这些元素组合是土壤分类两个要素的重要参照系；(3)浅层土壤的地球化学特征不可能完整地体现成土条件、成土过程和土壤属性这三个发生分类依据，因此，聚类分析结果与发生类型之间存在一定的差异。

On the basis of analyzing the classification principle of Bayesian classification model and a variant of Bayes theorem, a new classification model based on Bayes theorem, DLBAN (double-level Bayesian network augmented naive Bayes), which adds the dependence among attributes by selecting the key attributes, is proposed.

通过分析贝叶斯分类模型的分类原则以及贝叶斯定理的变异形式，提出了一种基于贝叶斯定理的新的分类模型DLBAN(double-level Bayesian network augmented naive Bayes)。该模型通过选择关键属性建立属性之间的依赖关系。

After having reviewed, analyzed and discussed the history and advances of research on theories and methods of landscape classification between our country and others, based on the basic theories, principles and foundations, The paper combined the current situations and characteristics of the rural landscape of our country, put forward a kind of method of rural landscape classification named the method of functional and configurational classification which served rural landscape planning of small scale.
