The monotypic genus Macrovalsaria previously of uncertain taxonomic position turns out to be a member of Botryosphaeriales and seems to be related to Botryosphaeria. The placement of Neopeckia and of Dothidotthia is in Dothideales and Botryosphaeriales, respectively. The genera Plowrightia and Botryosphaeria as currently defined are not monophyletic. Species of Plowrightia appear to be associated with three genera, Dothidea, Neopeckia and Sydowia; those of Botryosphaeria tested are recognized as three groups.

结果还显示，座囊菌纲中分类地位不确定的属Macrovalsaria与Botryosphaeria的关系相对接近，应该归于葡萄座腔菌目；历史上分类地位有疑问的Neopeckia和Dothidotthia两个属处于不同的目中，前者属于座囊菌目，后者为葡萄座腔菌目的成员；座囊菌目的Plowrightia属并非单系群，该属成员分别与Dothidea、Neopeckia和Sydowia三个属聚类在一起；现行的Botryosphaeria属也非单系群，其属的概念有待澄清。

Triangular adjustable fuzzy number is adopted to investigate the experts' suggestions in this paper, which effectively avoids AHP's problem of consistency check. The multi-experts decision is made convergence twice by means of the cluster analysis theory. The first convergence resolves the problems of abnormal value, which reduces the electivity and subjectivity of the experts' suggestions.

本文利用三角可调模糊数调查专家意见，然后利用加权综合解模糊化方法求出权重，有效避免了层次分析法一致性检验的问题；应用聚类分析原理对群体专家决策进行两次收敛：第一次收敛解决了异常值的问题，尽可能降低了专家意见的随意性和主观性。

UPGMA cluster analysis based on Nei's unbiased measures of genetic identity was assayed for five geographical groups of Elymus nutans, indicating that there was a significantly positive correlation between genetic differentiation and geographical habits among the five groups.

对各地理类群基于Nei氏无偏估计的遗传一致度的聚类分析表明，各地理类群间的遗传分化与其所处的地理生态环境具有较高的相关性。

Nevertheless, the results strongly supported that 1 Pyxidea mouhotii and Cuora aurocapitata formed a monophyletic clade, whereas Cyclemys atripons was not closer to the Pyxidea-Cuora than to Chinemys reevesii, suggesting that Cyclemys and the Cuora group may have originated from two ancestors; 2 the Geoemydidae with Testudinidae was a sister group rather than with the Emydidae.

结果表明：锯缘摄龟和金头闭壳龟构成单系支，白腹摄龟与此聚类支的亲缘关系较乌龟远，暗示齿缘摄龟属和闭壳龟组可能起源于两个不同的祖先；淡水龟科和陆龟科而不是龟科互为姐妹群。

Methods XbaI was used to digest the total DNA of Salmonella enteritidis strains isolated from the food poisoning samples.

对食物中毒中分离的肠炎沙门菌用XbaI酶切总DNA，用脉冲场凝胶电泳法进行分子分型，用BioNumerics软件对PFGE分型图谱进行电子化数据分析，绘出聚类分析图。

Methods Gene analysis by analysis susceptibility, ERIC-PCR techniquea and plasimid fingerprinting were put into practice for the detection of gene variation of 10 strains of Salmonella enteritidis. The similarities between different strains were obtained by software NTSYS-PS 2.0 for cluster analysis.

药敏试验采用K-B法，用碱裂解法提取细菌的质粒DNA，采用肠杆菌重复基因间隔重复共有序列技术对10株肠炎沙门菌进行基因分析，运用NTSYS-PC2.0软件进行同源性比较，聚类分析。

The information about the cocoon quality most similar to the new lot cocoon can be found out to determine its cocoon cooking parameters based on the fuzzy mathematical assembly, the fuzzy correlation matrix obtained from establishing an equiform priority ratio, and data accumulated for years in the factory.

本文运用模糊数学的聚类分析和建立相似优先比，以构造模糊相关矩阵的方法，从工厂历年所积累的资料中找出与新庄口最接近的茧质资料，以确定新庄口相应的煮茧工艺参数，并联系生产实际问题作了初步分析。

The clustering result by Neighbour Joint clusterinhg method indicated Nipponia Nippon, Plegadis falcinellus and Platalea alba were firstly clustered together, which was identical with the results of morphological observation.

利用NJ法对18个个体的mtDNA Cyt b基因序列进行聚类，结果表明朱鹮与非洲琵鹭和彩鹳具有较近的亲缘关系（分别为0.0932，0.1170～0.1249），与形态学的观察相一致。

Faunistic composition analysis showed that geographic units in Anhui Province could be divided into two groups along a boundary from northern Dabie Mountain to Chaohu Lake. Indomalayan species accounted for 60% of the total species in all geographic unit groups, with an increase in the group's prevalence from north to south.

基于分布型物种数的地理单元聚类分析结果表明，安徽省鸟类地理分布区大致以大别山北缘－巢湖一线为界分为两大组，两组在区系成分上存在较大的区域分异；东洋型物种在整个安徽境内比例均占60%以上，同时呈现由北向南递增的格局。
