二聚的

When a multisubunit complex is activated at the plasma membrane, one of its subunits is released.

通常的产物是同源二聚体，但有时也会是异源二聚体。

They had suppressed the cathodic process of carbon steel electrode. Their inhibition performance was also related with their molecule stereo conformation and electron configuration. Four of bis-(1, 1'-benzotriazoly)-α,β-diamide compounds linked via-CO 〓CO-chain were synthesized and certified by IR and 〓H-NMR. The minimum energy conformations of these compounds were obtained by MM2 forcefield program. The two benzotriazole moiety in BBT1 was more planar than in other compounds. This was beneficial in increasing the inhibition effects of BBT1. In 0.5M H〓SO〓 solution, BBT1 suppressed anodic corrosion reaction. In 3%NaCl solution, BBT1 suppressed both cathodic and anodic corrosion reactions. 1- [ (1'-imidazolly)-methyl] benzotriazole was synthesized by Mannich reaction.

合成了四个通过-CO〓CO-连接的双（1，1'-苯并三唑）-α，ω-二酰胺化合物，采用MM2分子力学程序优化了它们的分子结构，双（1，1'-苯并三唑）-α，ω-二酰胺化合物的缓蚀作用与其分子内两个苯并三唑单元的空间取向有关系，良好的平面性有利于苯并三唑二聚体的吸附和缓蚀作用，苯并三唑二聚体BBT1分子内两个苯并三唑单元近似平行，所以显示出较好的缓蚀效果。0.5M硫酸中BBT1主要抑制铜的阳极溶解的电化学反应；3％NaCl溶液中，BBT1对铜的阳极溶解和氧的阴极还原过程均有抑制作用，相比较而言对阴极过程的抑制作用更大一些。

In contrast, dimerization and trimerization of NaH2PO4 are predicted to be the predominant initial reactions for the silica supported NaH2PO4 catalyst.

In contrast,dimerization and trimerization of NaH_2PO_4 are predicated to be the predominant initial reactions for the silica supported NaH_2PO_4 catalyst.

但是在二氧化硅负载的磷酸二氢钠上，磷酸二氢钠的二聚和三聚是缩合反应初始阶段的主要反应。

It is shown that the methanol dimer and methanol cluster are the predominant species of methanol in gaseousness. So we believe that rather the methanol dimer is the original reactant of the methanol dehydration reaction to dimethyl ether than the mono-methanol.

研究表明，在气相中，甲醇分子主要以二聚体和多聚体的形式存在，据此提出甲醇脱水反应的原始反应物是甲醇二聚体，而不是单个甲醇分子。

The oligomerization of isoprene with titanium tetrachloride as catalyst and alkylaluminium chlorides as promotor was studied, and especially the effects of the reaction conditions on the synthetic activity and selectivity of dimer and trimer were investigated in detail.

In order to mimic this repair process of apoenzyme, we synthesized two model compounds, in which tryptophan and/or tyrosine was covalently linked to cyclobutane thymine dimer, and measured the splitting quantum yield of dimer under 295 nm light. By investigating the photosensitized splitting properties of the dimer, some new insights into the intramolecular electron-transfer process were gained.

为了模拟酶蛋白的这一修复过程，合成了色氨酸和/或酪氨酸与胸腺嘧啶二聚体共价连接的化合物，作为酶-底物复合物的模型，研究了它们在295 nm光照射下氨基酸残基光敏化二聚体裂解的性质，测定了二聚体裂解量子产率，获得一些新的结果并对其进行了分析。

DFA-PEG polyester was synthesized with DFA and PEG 400 at first, and then bysulfating DFA-PEG polyester with NH_2SO_3H or terminating DFA-EG polyester withrosin acid, two derivant, these are sulfated DFA-PEG polyester and terminateDFA-PEG polyester, were synthesized. The reaction conditions of synthesis wereoptimized by orthogonal experiments.The molecular weight of product was analyzed by GPC.

SDS-PAGE showed that fusion proteins had a disulfide-bonded dimeric structure and existed as homodimer.

SDS-PAGE结果显示该蛋白具有通过二硫键结合的二聚体结构并以同源二聚体的形式存在。

The results from GC-MS and GC analysis confirmed that the oligomer was a mixture consisting of di-(14%),tri-(45%),tetra-(31%) and pentamer(10%).

GC-MS和GC的分析结果表明所得齐聚物是混合物，主要由二聚体、三聚体、四聚体和五聚体组成。

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。
