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、分类堆砌有助於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。

Widely accepted as they are, the classification of pyroclasts and the petrographic classification of pyroclastic rocks stipulated by the IUGS Subcommission on the Systematics of Igneous Rocks fail to consider the classification with Chinese characteristics, which was put forward in 1950s to 1960s and improved in 1980s to 1990s and has since been widely used in China.

Many polarimetric target decompositions were explored, and support vector machine was applied to the classification of polarimetric SAR image. A new algorithm of target classification was presented based on polarimetric target decomposition and support vector machine. Finally, the effect of classification results was discussed by selecting different kernels and different parameters.

This dissertation brings forward and realizes the multilevel classifiable method which is based on characters coding. Above all, this method realizes the first-grade classification by extracting enough effective characters from characters and coding them, to the others which couldn't be recognized by the first-grade classification, the method will adopt the second-grade classification using template matching to recognize these characters.

本文使用了基于特征编码的多级分类识别方法，通过给字符抽取足够多的有效的特征并给特征编码实现第一级分类，对于第一级分类后仍不能区分的字符，再进入第二级分类用模板匹配的方法最终达到区分的目的，这种方法的重点在第一级分类阶段。

A novel kind of Ordination-Fuzzy min-max neural network based on non-metric multidimensional scaling was proposed to solve the classification problems of unlabeled input pattern. Firstly, all the input patterns were sorted by MDS to get their similarity measures. Then these measures were used to supervise the following expansion and contraction stage of hyperboxes for classification. OFMM had improvements both in the validity of unlabelled patterns classification, and the network structure and training time.
