二聚的

These findings are consistent with functional NMDA receptors being arranged as a dimer of dimers.

这一结果也进一步支持NMDA受体的装配是一个二聚体的二聚化过程。

介绍了一种混合碳四烯烃叠合利用的预反和催化蒸馏组合技术，该技术以酸性阳离子交换树脂为催化剂，可以将混合碳四烯烃中的95%以上的异丁烯叠合反应生成二异丁烯和异辛烯，且部分正丁烯也参与二聚或共聚。

Effects of vapour of organic solvents on the poly- was studied by the differential scanning calorimetry.

用差示扫描量热研究了几种有机溶剂蒸气对聚对苯二甲酸乙二酯的作用，表明可分为反应性的和非反应性的两种。

Di-cyclopentadiene deserves to be mentioned for its simple decomposed product,cyclopentadiene,and its low-price.

尤其是双环戊二烯的分解产物单纯，仅有解聚后的环戊二烯一种，且价廉、易得，值得重视。

Results The diagenetic grade of Permian rift basin was quite high, and the mechanical compaction resulted in the great loss of the original pore. The eodiagenesis and telodiagenesis were important to the reservoir, and fractures were the dominant hydrocarbon migrating pathway and accumulating space; In Triassic-Paleogene Formation, mechanical compaction was as important as pressolution, and the most original pore was preserved. The exodiagenesis stage of late hercynian movement, indosinian movement and Yanshan movement played the vital role in the diagenetic evolution and hydrocarbon migration and accumulation of the basin. The argillaceous dolomite and algal dolomite discaved in Permian, which were formed probably by hybrid process in high salinity lake which had the fresh water interfused in.

结果 二叠纪裂谷盆地的成岩强度大，以机械压实作用为主，原生孔隙丧失多且早，晚期成岩作用较重要，裂缝是油气运聚的通道和空间，可出现次生孔隙发育带；三叠纪－古近纪拗陷盆地的成岩作用表现为机械压实和化学压实作用并重，原生孔隙多被保留；晚海西、印支、燕山运动等表生成岩阶段对该区的成岩演化和油气运聚起到重要作用；二叠系中特征的泥云岩和藻云岩可能是在有淡水注入的较高盐度湖泊中经混合作用而形成的。

Synthesis of tricyclopentadiene Two methods of polymerization were analyzed in the synthesis of TCPD: thermal polymerization of DCPD, Diels-Alder reaction of DCPD and cyclopentadiene.

三环戊二烯的合成采用两种方式对TCPD的合成进行了研究：DCPD直接热聚法、DCPD与环戊二烯双烯加成法。

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。
