It indicated that a considerable degree of genetic differertiation has taken place in the A and B genomes of two species during evolution from wild emmer to common wheat.2 The similarities co-efficiency of A genome of common wheat and wild emmer was slightly higher than that of B genome.

野生二粒小麦与普通小麦A染色体组的遗传相似性高于两物种B染色体组的遗传相似性，从而说明小麦的不同染色体组在进化过程中的遗传速率或者说进化中的稳定程度是不同的。

E is studied. During research on many distance functions, I adopt two ways to compute the similarity of the case which include Heterogeneous Euclidean Overlap Metric and p?

其次进行了预案相似度的研究，说明了一些距离函数，文章采用了引入权重的相似性计算方法和基于HEOM(Hetetogeneous Euclidean-Overlap Metric)的方法，来计算灾害预案的相似性。

The similarity measure of the clustering objects heavily affects the cluttering result, so the author studies the problems about similarity measure, and proposes a generalized distance.

聚类对象的相似性度量对聚类结果的影响很大，因而研究了聚类中的相似性度量问题，提出了广义距离概念。

In this study, a novel artificial immune system algorithm for unsupervised classification and recognition is proposed by using a novel manifold distance based dissimilarity measure which can measure the geodesic distance along the manifold.

摘要将一种新的流形距离作为相似性度量测度，提出了一种用于无监督分类与识别的人工免疫系统方法。通过基于流形距离的相似性度量，有效利用样本集固有的全局一致性信息，充分挖掘无类属样本的空间分布信息，对样本进行类别划分。

Moreover, we illustrated the method by examining similarity or dissimilarity of exon-1 ofβ-globin gene of 11 species, and compared our results with some existing results of other methods.

以11种生物的β-globin基因的第一外显子为例分析了序列间的相似性，并同其它文献中的相似性分析的结果进行了比较。

Moreover, we illustrate these methods by examining dissimilarity of exon-1 of β-globin gene of 11 species, and compare our results with some existing numerical methods.

根据向量之间的欧氏距离，我们分析了11种生物的β-globin基因的第一外显子序列的相似性，并同其它文献中的相似性分析的结果进行了比较。

It can be inferred that there was an organization organ peculiarity for SOD in T. halophila in same stage.Studying of zymogram of isoxymes in T. halophila and A. thaliana, the POD isoxymes of T. halophila were unstable and different in special organ, the leaves of T. halophila in different developmental stage produced the same number but the different kinds of zymogram of isoxymes. It inferred that it was the way of halophyte plant that adjusted to the changes of environment. But the POD isoxymes of A. thaliana were stable and similar in special organ, and there were the same bands in different developmental stage.

对盐胁迫下盐芥和拟南芥同工酶谱带的比较可以看出，盐芥的POD同工酶在特定器官中并不具有高度的稳定性和相似性，不同的发育期盐芥叶片中产生相同数目但不同种类的同工酶谱带，即盐芥在不同的发育期具有不同的同工酶谱带，推测这种方式可能是盐生植物适应环境变化的方式之一；但拟南芥POD同工酶在特定器官中具有高度的稳定性和相似性，不同的发育期不同的组织器官内具有相同的谱带。

The phylogenetic trees revealed the GD3 strain was a intergrade virus strain evoluated from classical PRRV CH-1a strain to the PRRSV JXA1 and HUN4 mutant strains indicated by 97.1 %, and 97.2 % nucleotide homology with JXA1 and HuN4 strain, 94.9% nucleotide homology with CH-1a strain.

序列分析结果表明，GD3株在分子遗传演化上介于PRRSV变异毒株(HuN4 株、JXA1株)和CH-1a之间，与HuN4和JXA1之间的相似性为97.1 %和97.2 %；与CH-1a的核苷酸相似性为94.9 %。

It is found that there are similarities in terms of spectral integral among the wind input source terms given by Jeffreys, Sverdrup and Munk, and Plant and among the wave breaking dissipation source terms given by Tsikunov,Hasselmann and Philips,although the original forms and the physical considerations of these source terms are significantly different.

发现Jeffreys，Sverdrup和Munk以及Plant的风能输入源函数在谱积分意义下具有相似性，而Tsikunov，Hasselmann和Phillips的破波耗散源函数在谱积分意义下也具有相似性，尽管这些源函数的原始形式和物理背景显著地不同。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
