In this paper, we prove that if Ф is parallel and A+G+μB=0 for some functions λ,μ, then Ф=0, which gives the classification of the hypersurfaces in S(superscript n+1) with parallel Mbius form and A+G+μB=0 from the classification theorem in paper of Li H.

本文证明了如果x的Mbius形式Ф平行，并且A+λG+μB=0，其中λ，μ分别是定义在M上的光滑函数，那么Φ=0，由此及李海中、王长平（2003年）文献中的分类定理给出了S(上标 n+1)中具有平行的Mbius形式及满足A＋λG+μB=0的超曲面的分类。

Forexample, the group 2, 4 and 10 of BOX-PCR were good agreement with group 5, 13 and12 of numerical analysis, and the group 3, 4 and 8 of RAPD were equal to group 6, 12and 8 of numerical analysis, and the group 5, 6 and 8 were identical with group 6, 12 and8 of numerical analysis, which indicated the 4 methods used could reveal the biodiversityamong the tested free-living nitrogen fixation strains.

总的来说，本研究所采用的表型分群和遗传型分群的结果在总体趋势上是一致的，BOX-PCR的群2、4和10分别与数值分类中的第5、13和12表观群一致；RAPD的群3、4和8分别与数值分类的群6、12和8相对应，16S rRNA PCR-RFLP中的群5、6和8则数值分类的群6、12和10完全吻合，说明本实验所获得的研究结果可信。

In many ways, reclassification may be compared to changing colors on a map , in that the reclassified attributes may plot out in new colors.

在钗h方法中，重新分类常被比喻成在地图上改变颜色，而重新分类后的属性就像在地图上的改变后的新颜色。

We also use an evolutionary factor of gener ation ability to make resulting SVMs adaptive on classifying precision and guara ntee the generation ability of them.

同时引入泛化能力进化因子，使得结果SVM在分类效果上具有自动调整能力，并防止分类能力的退化。

Aimed at the study of Lauraceae system classification in domestic and overseas,genetic diversity and genetic variation between Cinnamomun micranthum Hayata natural populations and Ex-situ conservation poputations and relationship among Its Close Relative Species of Cinnamomum camphora Presl,Cinnamomum burmannii(C.G.etTh.Nee) Bl,Phoebe bournei Yang. Litsea subcoriacea Yang et P.H.Huan. Neolitsea aurata Koidz,Lindera communis Hemsl and Persea Americana Mill.were studied by inter-simple sequence repeats molecular marker.The research aimed at genetic variation between Cinnamomun micranthum Hayata populations,so that can offer the molecular theoretic and practical method for conservation and utilization of Cinnamomun micranthum Hayata populations.

针对目前国内外对樟科植物系统分类的研究现状，本研究采用ISSR分子标记技术对樟科沉水樟天然居群和迁地保护居群的遗传多样性进行研究，从分子水平上分析沉水樟种群的生态遗传及其遗传变异规律；同时利用ISSR分子标记技术比较沉水樟及其近缘种香樟、阴香、闽楠、桂北木姜子、新木姜子、香叶树、鳄梨在分子水平上的亲缘关系，揭示这些树种在樟科植物系统进化中的作用与地位，探讨沉水樟及其近缘种的遗传多样性及其分化格局，为樟科植物的系统分类提供分子水平的依据。

While the physiological and biochemical function and other taxology methods were need to combined for the exist of some differences between them.

另外，在一些生理生化反应上，二者又有较大的差异，体现出了它与分子分类在内的其他分类方法相结合，以共同准确地确定粘细菌的真实分类地位的必要性。

It is a long way to go to give a scientific classification on the basis of sufficiently numerating and determining the scope of environment protection activities, especially in the sense of practical operation.

如何在充分列举、确定环保活动范围的基础上，进一步进行科学的分类，满足分类核算进而分类分析的要求，还有很长的路要走，尤其在实际操作这样的层面来考虑问题。

Firstly, we summed up the process and results of historical research. And then we classified the action morpheme and the noun morpheme. Based on the classification, we analyzed noun morphemes in order to find which kind of noun morpheme is strong to unite and which is the weak ones to centre around the action morpheme. Then we stated, analyzed and accounted for the usage of different semantic categories used in the line situation. We found that action morpheme combined into one by moving the line word was the main line and the main format, and explored and analyzed the role of analogy of noun morpheme line to other formats. Line formation of the word has its own reasons, so the article concluded by examining the formation of the line words' language, social and other reasons at last.

文章着眼于对动、名语素组合成的离合词的语义构成进行分析，探讨了动、名语素组合成离合词的语义选择规律，以动、名语素的语义分类为基点，在分类的基础上，以动语素为中心，分析围绕动语素的名语素义类，分析哪些义类名语素和动语素组合成离合词的能产性较强，即组合的周遍性和数量频度上是最高的，哪些义类组合成离合词的能产性比较弱，试图寻找动语素与名语素组合成离合词在义类上的能产性和周遍性，然后再对不同语义类组合中离合运用的情况进行统计、分析、说明。

This thesis reviewed the historical development, the current taxonomic status and the phylogeny of rhizobia, and compared the main methods applied in rhizobial polyphasic taxonomy.

本论文综述了根瘤菌的分类现状、系统发育地位及有关的研究方法；采用数值分类、16S rDNA PCR-RFLP、BOX-PCR、AFLP、16S rDNA 序列分析、G+Cmol%测定、DNA-DNA同源性分析等多相分类技术对分离自我国不同地区的木本豆科植物刺槐、黄檀、合欢根瘤菌进行了系统地分类学上的研究。

After the vein pattern was segmented from the vein image by an improved NiBlack method,authors obtained the vein pattern skeleton by an improved conditional thinning algorithm.On the basis,the algorithm extracted seven modified moment invariants of the vein pattern skeleton as the input vector of SVM for the recognition of vein pattern.The experiments on a database including 500 samples has achieved a recognition rate of 95.5%,and it indicates the algorithm is effective.
