同义

The synonyms, which are formed by monosyllable, are 26%, and the synonymas, which are formed by monosyllable or disyllabic word, and formed by disyllabic word, are 74%.

其中单音节和单音节构成同义词的只占总数的26％，也就是说单音词和双音词构成的同义关系和双音词之间构成同义关系的占到了74％。

The results show that both of relative rate and synonymous and non-synonymous coden substitution in eudicot clade are significantly higher than those in monocot clade, and the value of dN/ds uncovered possible positive selective pressure in eudicot clade.

结果表明：真双子叶植物分支中SQUA类基因的相对速率和同义与非同义置换位点均显著高于单子叶植物分支；同时，dN／dS值表明真双子叶植物分支中可能存在正选择压力。

Recently polypod ferns have been demonstrated to undergo diversifications in the Cretaceous after the rise of angiosperms. To further test this proposal, an adaptive evolutionary analysis was performed on the rbeL gene sequences of Polypodiaceous ferns under models allowing w (nonsynonymous/synonymous rate ratio) to vary among sites.

为验证蕨类植物在白垩纪适应被子植物兴起而发生分化的观点，本研究以水龙骨科附生蕨类为对象，利用位点间可变ω（非同义替换率d和同义替换率d的比值）模型对其rbcL基因的适应性进化进行分析。

Many agree that Christmas has become synonymous with the cash register instead of the creche.

许多人同意，与其说耶诞节是「婴儿诞生马厩图」的同义辞，不如说更接近「现金收银机」的同义辞。

SQUA genes of Dendrocalamus latiflorus were sequenced, and phylogenetic form on SQUA genes in angiosperms was analyzed. Relative rate and adaptive evolution after SQUA gene duplication in recent common ancestor of monocots and eudicots were analyzed using the methods of relative rate test, statistic on synonymous and non-synonymous coden substitution sites and likelihood rate test.

测定了麻竹的SQUA基因序列并分析了被子植物中SOUA类基因的系统发育式样；采用相对速率检验、同义与非同义置换位点统计以及似然比检验方法，分析了单子叶和真双子叶植物最近共同祖先中SQUA基因发生基因重复后的进化速率与适应机制。

The nonsynonymous substitution sites were more than synonymous substitution sites in human, house mouse and pig obviously.

人、家鼠和猪的非同义替换位点数明显高于同义替换位点数。

Over the past two decades, there have been several approximate methods that adopt different mutation models and used for estimating nonsynonymous and synonymous substitution rates based on protein-coding sequences across species or even different evolutionary lineages.

比较基因组分析是研究生物进化关系的基本工具，非同义替换率和同义替换率的计算是研究分子进化动力学的重要内容。在过去的二十多年，基于马尔科夫链的核酸替代模型一直在不断发展。

Over the past two decades, there have been several approximate methods that adopt different mutation models and used for estimating nonsynonymous and synonymous substitution rates based on protein-coding sequences across species or even different evolutionary lineages.

近日，中国科学院北京基因组研究所基因组科学及信息重点实验室通过引入新的参数构造模型，发展了一个新的ka/ks算法，该研究成果在近期出版的 Biology Direct 杂志上发表。比较基因组分析是研究生物进化关系的基本工具，非同义替换率和同义替换率的计算是研究分子进化动力学的重要内容。

All kinds of these study results, including analyzing the nucleotide composition, the amino acid composition, the nucleotide diversity, the synonymous and the nonsynonymous, the transition and the transvertion, the frequencies of the codon used, the construction (including four stems and four loops) of tRNAleu,the phylogeny,suggest that great distinctness present among the genera and small difference even none among species.

在各种分析中(包括核苷酸基本组成分析；氨基酸基本组成分析；核苷酸多样性分析；非同义替代和同义替代分析；密码子使用频率分析；转换与颠换分析；tRNAleu基因的四臂四环二级结构分析；&翻译启始&和&翻译终止&在进化过程中的变化；系统发育分析)，属间的差异相当明显，而种间差异很小甚至是没有任何不同之处。

The results show that in peptide chain, the residue at the first position C-terminal influences the usage of proline synonymous codon greatly and proline synonymous codons contain some factors influencing the isomerization of the prolyl peptide bond.

研究结果表明：与脯氨酸相邻的C端第一个残基对脯氨酸同义密码子的使用有较大影响；脯氨酸同义密码子内携带有影响脯氨酸肽键构象的因素。

As she looked at Warrington's manly face, and dark, melancholy eyes, she had settled in her mind that he must have been the victim of an unhappy attachment.
