The application to phylogenesis of gene rearrangement of mtDNA in Anura groups was analyzed. It showed that the higher Anura was, the more complicated gene rearrangement became.

本文分析了蛙类mtDNA基因重排多样性，并探讨了蛙类mtDNA基因重排在系统发生关系上的应用，发现越高等的物种，其线粒体基因重排越复杂。

Autoreduction of Pt〓 ionsin β zeolite is found directly by means of CO-IR and TPR methods.

A condition that can occur on a bothway data circuit used for common channel signalling when the exchanges at either end seize the circuit at approximately the same moment.

在公用通道信号系统所用双向数据线路上，当两端的交换机几乎同时要占用线路情况下发生的一种状态。

So cast measurement is used to complete the cephalogram. But cast measurement studies are referenced to the changing occlusion plane.

而模型研究只能以同样处于变化中的〓平面作为参照，很难与相对不变的颅骨参照系统发生联系。

The study show that symbol timing offset and sampling frequency offset would introduce inter-symbol interference, frequency offset of carriers would result in intercarrier interference.

然后，就同步误差对系统性能的影响进行了详细分析讨论，分析表明，定时偏差和采样频率偏差将会引入码间干扰，载波频率偏差导致载波间干扰的发生。

The estimated number of nucleotide substitutions per site between genera Phasianus and Chrysolopus is 0.076 (rangs from 0.067-0.085), and between golden and Ch...

在雉科系统发生中，雉属与锦鸡属是近缘的属；2。红腹锦鸡和白腹锦鸡的分化较晚，关系密切，可能只是两个亚种。

The polygenetic analysis of these sequences indicated that the main character for cystatin genes might have been existent before the split of Arabidopsis and rice.

系统发生分析表明，cystatin基因的基本特征很可能是在拟南芥和水稻的分离之前就已经形成。

Answer riving on the highway, I realized that enormous changes had taken place in China's highway system in recent years.

驱车行驶在高速公路上，我意识到近几年来，中国的公路系统发生了巨大的变化。

Based on the complete sequences of the mitochondrial 12S rRNA and Cyt b genes, and the combined sequences of the two genes, the phylogenetic relationships among all extant zokors except the Siberian zokor (M. myospalax) and the Smith's zokor .

根据线粒体12S rRNA基因和Cyt b基因全序列以及合并的序列数据分别研究了鼢鼠亚科已知所有物种（除阿尔泰鼢鼠Myospalax myospalax和斯氏鼢鼠M.smithi）的系统发生关系。

Therefore, the influential factors of happening and spread of fire brought by sediment in air-conditions system were analyzed. The experiments selected sawdust as a kind of sediment.

本文中对通风空调系统中的聚积物导致火灾发生和传播的影响因素进行实验分析。

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.

索夫农 、森那库斯和苏格拉底式的对话采用的模仿没有一个公共的名称；三音步诗、挽歌体或其他类型的诗的模仿也没有——人们把&诗人&这一名词和格律名称结合到一起，称之为挽歌体诗人或者史诗诗人，他们被称为诗人，似乎只是因为遵守格律写作，而非他们作品的模仿本质。

The relationship between communicative competence and grammar teaching should be that of the ends and the means.

交际能力和语法的关系应该是目标与途径的关系。
