NF-κB is a kind of important nuclear factors which are relative to lots of cellular activities such as activation of immunocyte, development of T and B lymphocyte, stress reaction, cell apoptosis and so on. NF-κB exists in almost all types of cytoplasm in the unreactive form of heterodimer or homodimer.

另外，在研究温度对它的曲线影响时发现，温度对合成的二聚表面活性剂成膜的影响很小，而这种结构的单体受温度的影响非常明显。

On the other hand, so far as we know, the characterized catalase is the first dimeric monofunctional catalase from alkaliphiles and is also the first monofunctional catalase derived from a natural soda lake, which could partially reflect the oxidative stress response in the corresponding environment.

另一方面，本文所研究的过氧化氢酶是第一个来源于嗜碱微生物的同源二聚体单功能过氧化氢酶，也是第一个来源于天然碱湖的单功能过氧化氢酶，它能部分地反映出细胞抗氧化体系对相应环境的适应情况。

He best reaction conditions of TMAA were as follows: p-benzenediol as the polymerization inhibitor and the amount 1% of acrylic acid, reaction temperature 180 ℃,reaction time 3 h, raw material mass ratio of methyl eleostearate /acrylic acid 1:0.247 and the yield of TMAA was 85%.

The reaction proceeds by ethene chemical adsorption to form the surface ethoxide and the C-C bond formation between the ethoxide and the second ethene molecule to form the butoxide product.

乙烯化学吸附生成的烷氧化合物与物理吸附的乙烯分子发生二聚反应生成新的C-C键同时生成新的烷氧化合物。

TGF-βbinds to a heteromeric complex of type I and type II receptors. The constitutively active type II receptor phosphorylates and activates the type I receptor which phosphorylates Smad2 and Smad3 (receptor-associated Smads). Receptor-associated Smads bind the common mediator Smad4 and are translocated to the nucleus, where they associate with DNA-binding cofactors to modulategene transcription.

TGF-β与其效应细胞表面的Ⅱ型受体TβRⅡ和Ⅰ型受体TβRⅠ形成的异源二聚体结合，相继激活TβRⅡ和TβRⅠ，活化的TβRⅠ再进一步活化Smad2和Smad3，磷酸化的Smad2/3必须与Smad4结合形成复合物，才能进入细胞核，调节靶基因的转录[6]。

TGFβ is a kind of homotype dimer polypeptide. It shows a high affinity with serine/threonine recipient albumen. It also has an extensive biological effect and features the function of restraining the proliferation of several kinds of cells and helping the inflammationand wound healing.

TGFβ是一种同型二聚体多肽，与跨膜丝氨酸/苏氨酸受体蛋白具有较高的亲和性，具有较广泛的生物学效应，较显著的是抑制多种类型细胞的增殖以及在炎症愈合和创伤愈合中的作用。

The multi-drug resistance rate of Salmonella and E.coli were 91.80% and 100%.According to the genes sequence published in Genbank ,we analysed the value of Tm ,content of G+C, oligonucleotide dimer by DNAStar and Primer 5.0 software, and according to the construction of I integron ,we designed 3 pairs of primers to amplify intIl gene ,variable segment ,3"-conserved segment for detectting Salmonella and E.coli"s I integron.As a result , aimed genes were amplified and sequenced;The detection rate of I integron of 61 Salmonella and 48 E.coli were 81.97% and 66.67%.

据文献报道及GenBank中注册的基因序列，运用DNAStar软件分析同源率及Primer5.0软件对Tm值、G+C含量、引物二聚体等进行分析，根据Ⅰ类整合子的结构设计了3对引物，对Ⅰ类整合子的intI1、可变区、3'保守端进行扩增，检测沙门氏菌和大肠杆菌Ⅰ类整合子；扩增出了相应基因片段并测序；61株沙门氏菌和48株大肠杆菌中分别有50株和32株菌检测出Ⅰ类整合子，Ⅰ类整合子的检测率分别为：81.97％和66.67％。

Through the use of high-level quantum-chemical calculations, two experimentally observed isoenergetic isomers are assigned to complexes in which a water dimer is hydrogen-bonded either to the carbonyl oxygen of the ester function or to the amino nitrogen.

通过高层次的量子化学计算上的应用，两个实验观察isoenergetic异构体被分配到复合物，其中一个水二聚体的氢键要么酯的羰基氧的功能或对氨基氮。

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。
