Neighbor-Joining analyses of teleost hepcidins showed that the eelpout 4cys variant arose independently from the notothenioid version, which lends support to adaptive evolution of reduced cysteine hepcidin variants on cold selection. The NJ tree also showed taxonomic-specific expansions of hepcidin variants, indicating that duplication and diversification of hepcidin genes play important roles in evolutionary response to diverse ecological conditions.

另外我们在另一种生活于南极水域的eelpout中也发现了一种含有4个半胱氨酸残基的hepcidin，而eelpout和南极鱼notothenioid在分类学上分属于不同亚目，是一类相差较远的物种，利用Neighbor-Joining方法建树分析发现eelpout的hepcidin虽然同样仅含有4个半胱氨酸残基，但和notothenioid的4cys_hepcidin有着不同的起源，这也进一步说明了hepcidin中半胱氨酸残基数目的减少确实是对寒冷环境的一种适应性进化。

The panel-furniture part joining tensile strength and simulate modulus of rigidity along with their connecter(dowel, eccentric connecter, hangnail fixed connecter, wood screw, wooden peg, adhesion and so on), base material influence factor and so on, which are joining spot and joining way are different but changes.

Apparently, the results is determined extremely by theoretical algorithm. In 147 zinc-finger-containing genes, 50nt identity sequences were extracted. The results hint that 15 genes may related to block evolution. we analyzed the phylogenetic map of these 15 genes by uncorrected distance, Jukes Cantor distance, Tamura distance, Tajima-Nei distance, Jin-Nei distance or Kimura distance correction, but we found no satisfied result according to the block exchange pattern mentioned before. Introducing Bootstrap test to assistant correction, an comparatively perfect map was drown by Neighbor Joining method.

以147个含锌指基因为模板，我们搜索了其中的50nt一致序列作为板块式进化的核心，获得15个相关基因，应用无校正距离、Jukes Cantor校正距离、Tamura校正距离、Tajima-Nei校正距离、Jin-Nei校正距离和Kimura校正距离等分析了他们之间的进化关系，结果与已知的板块交换模式吻合度较差，引入靴带检验对Jukes Cantor校正距离结果进行统计学校正，并重新用Neighbor Joining方法绘制进化图，结果可靠性大大提高。

This system also was considered a successful example in knowledgeacquisition and module joining.Key words:expert systems,milking machine testing,knowledge acquisi-tion,medule joining

另外该系统在模块连接，庞大表格知识的表示的技巧方面为其他知识工程师提供了一个很有参考价值的例子。

On the base of the constructing phylogenetic tree using PAUP 4.0, MP and NJ (neighbor-joining) trees of diverse pectate and pectin lyases showed that pectate lyases from plant, pectin lyases from fungi and pectate lyases from bateria belong to different groups, respectively. The pectate lyase A of Aspergillus nidulans is more closely related to plant pectate lyases than to pectin lyase from fungi and pectate lyases from bacteria. The pectin lyase from Pseudomonas syringae is more closely related to fungi pectin lyases than other lyases.

构建的MP树和NJ树(neighbor-joining)显示：来自植物的果胶酸裂解酶、真菌的果胶酸酯裂解酶、细菌的果胶酸裂解酶分别可聚为一个独立的类群；相对于细菌果胶酸裂解酶和真菌果胶酸酯裂解酶而言，构巢曲霉的果胶酸裂解酶A和植物的果胶酸裂解酶之间有较近的亲缘关系；细菌Pseudomonas syringae的果胶酸酯裂解酶和真菌的果胶酸酯裂解酶之间的亲缘关系较近。

Traditionally, when joining dissimilar materials is needed, solid phase joining, adhesion and mechanical joining are used.

传统上，当加入不同的材料是必要的，固相连接，粘接和机械连接的使用。

Because of sharing characteristics with both Galliform groups, Tragopans are classified as partridges by some authors and pheasants by some others. In this study we set out to sequence the cytochrome b-gene of 19 species pheasants. and took the sequence for those 22 species from GenBank. We amplified 828 base pairs using the PCR technique. Primers designed by ourselves were based upon Galliform sequence data. Neighbor-joining method and Minimum evolution method were used to analyse cytochrome b sequences with Anhima cornuta and Kachuga dhongoka as outgroups.

通过PCR扩增鸡形目Galliformes黄腹角雉Tragopan caboti等10个属19个个体的线粒体DNA细胞色素b的部分基因，获取片段长度为828bP，以及从GenBank获取22种样本的相应序列，以角叫鸭Anhima cornuta和海龟Kachuga dhongoka为外群，分别用邻接法(Neighbor-joining， NJ)和最小进化法(Minimum-evolution， ME)，对鸡形目和将雉科的15个属分为5个属及雉族和鹑族构建分子系统树，NJ和ME系统树中，都是角雉与雉类相聚。

Analyses of a neighbor-joining tree of identified DNA haplotypes and F values between samples, and an analysis of molecular variance revealed significant genetic differences between samples from Portugal and Taiwan, but no differentiation among the samples from Taiwan. These results suggested that the common mackerels off Taiwan belong to the single gene pool.

单基因型之neighbor-joining树、族群样本间之FST值及分子变方等分析显示葡萄牙及台湾之三族群样本间皆有显著之遗传差异，但台湾之三族群样本间并无显著差异；此结果指出台湾附近之白腹鲭属於单－基因库。
