相似性

The history of the word cappuccino exemplifies how words can develop new senses because of resemblances that the original coiners of the terms might not have dreamed possible.

cappuccino 一词的历史很好地说明了词语如何能因一些相似性而发展出新的意思，而这些词的创造者也许做梦都没想过这些相似性是可能的。

A novel kind of Ordination-Fuzzy min-max neural network based on non-metric multidimensional scaling was proposed to solve the classification problems of unlabeled input pattern. Firstly, all the input patterns were sorted by MDS to get their similarity measures. Then these measures were used to supervise the following expansion and contraction stage of hyperboxes for classification. OFMM had improvements both in the validity of unlabelled patterns classification, and the network structure and training time.

该模型首先利用非刻度—多维度收缩法对输入的所有样本进行了排序，然后获得样本间的相似性测度值，并利用该相似性测度值指导随后的分类器超盒扩张与压缩过程，从而使得该模型不仅提高了对未标记样本进行有效分类的性能，而且无论是在网络结构方面，还是在训练时间方面都有所改进。

Meanwhile, a new biger genetic group containing 6 cilicate sWains was formed, and it was different from the reference strains. The phylogenic tree of the representative sWains HLJ01 (GenBank accession EF031269) and HB 16 (GenBank accession EF031270) was constructed by analysis of the 16S rDNA full sequence, the results of analysis of 16S rDNA sequence revealed that swain HLJ01, HB 16 and Bacillus mucilaginosus and Bacillus edaphicus were located in the same phylogenic branch. HLJ01 and HB16 had high homology with Bacillus mucilaginosus in the phylogenic tree, but the 16S rDNA sequence of HLJ01 only has the identity of 96.7% with Bacillus mucilaginosus, and of HB16 has the identity of 95.5% with Bacillus mucilaginosus.

根据16S rDNA-RFLP聚类结果，选取供试硅酸盐细菌菌株HLJ01和HB16作为代表测定了其16S rDNA全序列，其Genbank序列登录号分别为EF031269和EF031270.16SrDNA序列分析表明：代表菌株HLJ01与HB16虽然与胶质芽胞杆菌位于同一个系统发育分支，但相似性分别只有96.7％、95.5％；与土壤芽孢杆菌的相似性则分别为94.6％和93.3％。

The similarity between 71.8% of 41 detected sequences and published clone sequences were less than 97%, which represented a new community and 15.3% of the clone sequences which identitied with GenBank clone sequences were under 85%, which may represent some new families or suborders.

在这些克隆序列中有71.8%的克隆序列同已知序列的相似性低于97%，属于放线菌的新类群，这些可能的新类群中有15.3%的克隆序列与已知菌株的相似性小于85%，这些克隆序列的分类地位都在科一级的分类单元上，有的可能分类地位更高。

This method is better than the same character based method for it compute the similarity by the concepts represented by the words and it also avoids the effect of data noise and data sparseness in statistic based methods.

由于目前句子语法结构分析的困难，利用句子中出现的词语的相似性来计算句子的相似性，是句子相似度计算的一个较好的思路。

These similarities and historical relevance feedbacks deposited in the neural network can be used in next retrievals to gain enhancement in the efficiency of the system retrieval.

提出了基于神经网络的交互式图像检索方法，系统根据用户对检索结果的评价，动态构造神经网络，描述图像之间的相似性；图像间的这种相似性以及本次检索结果可以作为以后检索的历史信息保存在神经网络中，从而提高下一次检索的效率。

4The low similarities betweenseed banks and the established vegetation were considered to be the consequences ofthe frequent presence in the established vegetation but not in seed banks of someperennial rhizomatous plants which mainly depended on vegetative propagation toregenerate;insignificant difference in the species composition of seed barks amongtransects, might be accounted for by the fact that the flood drift had functioned as adisseminator for propagules;and with the intensifying of the flooding disturbance,both species diversity and the similarity between seed banks and establishedvegetations declined.

4种子库与地上植被相似性普遍较低，其原因是主要靠营养繁殖以更新种群的多年生根茎植物经常在植被中出现而不在种子库中出现；受水淹干扰的样带之间种子库的种类组成差异不大，说明洪水漂移行使了繁殖体传播和散布的功能；随水淹干扰强度增加，种子库物种多样性指数减小，种子库与地上植被的物种组成相似性下降。

New laccase gene and its full-length cDNA were clone from genomic library and equalized cDNA library of Ganoderma lucidum. Similarity between the sequence and other laccase gene were analyszed with NCBI blast, the results show that the new gene belong to multicopper oxidases gene family and have 60-70% Similarity with other laccase gene.

从灵芝的基因组文库和cDNA均一化文库中克隆了灵芝的漆酶基因和全长cDNA，并通过NCBI Conserved Domain Search氨基酸序列的相似性分析及与其它真菌漆酶之间的相似性分析，证明得到的蛋白是一种新的multicopper oxidases，其蛋白质序列与其它已克隆漆酶基因的同源性在6 0～7 0％之间，并对论文克隆的漆酶基因的启动子和终止子进行了分析。

Although the dominant species were all green algae in winter and spring,there were some differences in species.

浮游植物相似性指数测算结果显示，冬季和春季的浮游植物种类组成差异很大，相似性指数仅为030。

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