On the basis of analyzing the classification principle of decision tree classifier and parallelpiped classifier , a new classification method based on normalized euclidian distance , called wmdc ( weighted minimum distance classifier ) , was proposed 通过分析多重限制分类器和决策树分类器的分类原则，提出了基于标准化欧式距离的加权最小距离分类器。
Combined with a preliminary study on the dispatching operation of the mid - route of south - to - north water transfer project , the definition of the water supply load is put forward and then various principles and criteria are given through the investigation and analysis made on the later supply concerned 结合南水北调中线调度运行初步研究，提出供水负荷的定义，通过供水负荷的调查分析，提出各种负荷的分类原则和标准。
Mainly thinking over ore - bearing rock series and giving consideration to ore - forming process , the author divides the gold deposits in fujian into four categories which include metamorphic rock category , volcanic rock category , sedimentary clastic rock category and igneous rock intrusive contact category 采用以容矿岩系为主体兼顾成矿环境和成矿作用的分类原则，把福建省金矿划分为变质岩型、火山岩型、沉积碎屑岩型和侵入岩内外接触带型四类。
The part in the manufacturing process is analyzed wholly . the labeling principle to parts and the dada expressing manner of part geometry model are established , by virtue of them , the multi - feature system - mfs inspecting model of part suiting for inspecting is accomplished . 3 对生产过程中的零件进行了总体的分析，确定了待示教零件的分类原则，以及零件几何特征的数据表达方式，由此得到适合检测的零件多特征系统( multi - featuresystem ? mfs )检测模型。
2 investigated the principle and the methodology of the classification about the form feature in engineering field . described the classification system of the form feature . 3 analysed the request of the form feature modeling and developed a prototype system of the feature modeling in the collaborative design environment 详细讨论了各应用领域形状特征的分类原则与分类方法，研究了较为完备的形状特征分类体系，这个分类体系不仅是形状特征库的建库基础，也是基于形状特征的局部操作前提。
According to water pollution levels , the lake was divided into three zones , and these are ( a ) relatively seriously polluted zone , ( b ) clean water resource protection zone and ( c ) less seriously polluted zone . the same result was confirmed by the fuzzy cluster analyse 根据千岛湖污染现状相似性，把千岛湖总体上划分为三大区域，即上游污染较重区、下游清洁水资源保护区和中游中等污染区，同时应用fuzzy聚类分析法对各个取样点污染状况进行聚类分析，结果也验证了上述的分类原则
According to thinking about the problems of categorizing books by persona in the widely wed three part classification method and the analysis of the connotation of established subjects , classification management and classification principles , the article holds that categorizing according to persons is neither scientific nor beneficial to international unification and norm 摘要本文通过对国内使用较广泛的三部分类法中存在的以人分类问题的思考，以及对所设类目的内涵及分类理论、分类原则等的分析，认为以人分类既不科学，也不利于与国际分类法的统一与规范。
In the session of the analysis and coordination of those static data of fittings , on the basis of the reformed data of fittings , the paper establishes both a scientific classifying principle and also a rational coding system , which resolved the problem of the fittings - data - standardization . in order to control the actuality and the rate of overlapped codes , the paper has designed data - preparation programs and data - switch programs and data - checking ones through database programming technologies 在对配件静态数据的分析整理及实施技术的研究中，基于重构后的配件数据，建立了科学合理的分类原则和编码体系，解决了配件数据的规范化和标准化问题，采用数据库编程技术，设计了数据准备、转换和检查程序，实现了对数据准确性和重码率的控制。
Finally the author analyses the necessity for the implementation of the classification system and proposes tha t in the practice and reform , the principles of position classification and interim position classification should be applied as much as possible . in the recruitment of public servants , it is necessary to abide by the principle of employing the personnel according to the work 最后，对公务员的职位分类制度实施的必要性进行了分析，笔者认为，在改革与实践中，应尽可能多地运用职位分类原则，坚持职位分类过渡的原则;其次，做到因事择人，先事后人;先职位，后品位。
