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。

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。

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。

This matter was dealt with is divided into three: Nearest Neighbor, Bilinear and Trilinear.

而这种处理的方式共分三种：Nearest Neighbor，Bilinear以及Trilinear。

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。

Based on conal selection principle and K-Nearest Neighbor method, a fault detection algorithm that can produce the valid detector to diagnose fault is designed by the three parts of immune vaccine, immune learning and immune response.

3基于克隆选择原理和K-Nearest Neighbor分类法按照免疫疫苗、免疫学习和免疫应答三个过程设计了能生成有效检测器的故障检测算法。

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。

To investigate the spatial-dependence of heterogeneity at multiple scales for a community, we selected a representative plot of 100 m×100 m in the mountainous evergreen and deciduous mixed broad-leaved forest in Sichuan, southwest China (102°50'E, 30°02'N).The location of every tree was mapped by compass, and all-scale analysis of spatial structure of forest community was conducted by the method of PCNM (principal coordinates of neighbor matrices).

为了解植物群落在多尺度下的空间变异规律及其对空间尺度的依赖，以川西南山地阔叶混交林为对象，在有代表性的地段设立100m×100m样地，采用传统的罗盘仪对树体的相对空间位置进行定位，运用主轴邻距法(principal coordinates of neighbor matrices， PCNM)对群落空间结构的多尺度（100m内）特征进行了研究。

Secondly, two physical models were constructed, which could model rough surface and describe the features of the earth surface, such as chine, neck, valley and hill, etc. According to difference method, the ""true"" volume of the physical models were measured, which was 13260cm3 and regarded as the analysis foundation of the precision of the volume that was calculate by DEM. The discrete dada of the models on a regular spacing of 1cm were collected by 3SPACE FASTRAK and the DEM was obtained by interpolating the discrete dada through GIS software. Based on the volume of the models calculated by DEM, different interpolating methods (IDW, Spline, Natural Neighbor, and Kriging) and variation of grid spacing of data were compared and their effects on precision of volume calculation were analyzed.
