1·The quaternary structure was classified using support vector machine method and Bayes method.

用支持向量机和贝叶斯两种方法对蛋白质四级结构进行分类研究。

2·A great many proteins, especially enzymes, are oligomeric and consequently possess quaternary structure.

很多蛋白质尤其是酶类，是低聚物，因此拥有四级结构。

3·Antibodies respond to the quaternary structure of proteins so their potential to cross-react with an alloantigen is very low.

抗体对蛋白质的四级结构产生应答，因此它们对同种异型抗原发生交叉反应的能力较弱。

4·Some proteins consist of more than one polypeptide chain, and the association of these subunits in the protein gives rise to the quaternary structure.

一些蛋白质不只是由一个多肽链组成的，并且这些蛋白质亚基的结构产生了四级结构的。

5·The structure of many proteins is mostly described in three levels, but a quaternary structural level must be considered if the protein consists of more than one polypeptide chain.

许多蛋白质结构主要用三种标准描述，但是如果蛋白质包含一个以上的多肽链，就必需考虑四级结构标准。

6·It is the classification for the Quaternary stratigraphies of Hebei Plain study to build a platform for the aquifer structure model of the North China Plain .

该文是在以往研究基础上对河北平原第四纪地层划分的一次探讨，其成果为建立华北平原含水层结构模型搭建了平台。

7·The electronic structure of a quaternary alloy has been investigated using EHT band calculation method.

用EHT紧束缚能带计算方法，研究了四元合金的电子结构。

8·Pyrene fluorescence probe was used to investigate the structure of the adsorbed layer of cationic surfactants primary amines and quaternary amines at the diaspore-water interface.

采用荧光探针法研究了在烷基伯胺和季铵盐阳离子表面活性剂在一水硬铝石表面吸附层结构。

9·The fast growth of the salt structure took place from the middle-late Pliocene to Quaternary, featuring quick and differentiated growth.

上新世中晚期一第四纪进入快速生长期，晚期盐构造生长速率高且差别大。

10·Furthermore, this method can also indicate the position of fracture structure, and can provide good evidences for geological mapping in the quaternary thick-sedimentary coverage area.

此外，该方法还能较准确地确定断裂构造的位置，在第四系厚沉积物覆盖区，可为地质填图提供较好依据。
