二元体系

Because land property right fuzzy, dual society economic structure, laws and regulations imperfect and so on reasons, the land-lost peasen...

由于土地产权模糊、二元社会经济结构、法律法规不完善等原因，农民失去了土地的同时也失去了相应的权益，土地的保障功能消失，但是失地农民的社会保障体系并没有建立。

For ternary system of formic acid-water-pentyl formate, the average absolute deviations of predictions for vapor-phase mole fraction of water and pentyl formate are 0.0292 and 0.0273, respectively, and for the equilibrium temperature is 0.94℃.

由关联得到的三对二元NRTL模型参数预测部分三元体系汽液平衡数据，计算值与实验值基本吻合。

To achieve the full use of land resource and meet the need for socialist economy, the paid land employment system, a new concept of the state-owned land employment has been founded after the reform and opening up of China, which allows private people, by paying land remise fund, to get the using right of the land and to build and also keep the buildings on the land, which formed the duality right system of land ownership and land employment right.

改革开放后，为实现土地资源的充分利用，适应发展社会主义市场经济的需要，国有土地实行有偿使用制度，创立了国有土地使用权的概念，允许私人以交纳土地出让金的形式取得土地使用权，在土地上建造并保有建筑物，形成土地所有与土地使用的二元权利体系。

A similar initiator, Et_2Zn/-Sparteine, yielded polys with threo-diisotactic -rich structure in the main chain, indicative of strongly asymmetric inducation in this system. In this case, no polymeric complexes in-site formed because of the intensive coordination between sparteine and Zn ions.The binary initiating system composed of Et_2Zn and n-BuLi combined the advantages of both metal alkyls, which gave the polymers with higher molecular weights and moderate optical activity ~(25_D =-97.1°～+24.3°.

Et_2Zn／n-BuLi二元引发体系综合了两种金属烷基化物的优点，得到了分子量相对较高(M_n=1.4x10~3～4.9×10~3)且含有手性超分子结构的光学活性聚合物；聚合物中锌含量的微小变化可引起聚合物光学活性明显改变，超分子手性与聚合物侧基的绝对构型存在关联。

The data of phase diagrams, thermochemistry, crystal structures, metastable phases and magnetism were collected and evaluated. More accurate phase diagrams and other information were provided.

广泛地收集整理Fe-RE(RE=Gd，Pr，Tb)二元系的相图、亚稳相、晶体结构、磁性和热化学等数据，完成了对这些资料评估工作，给出了体系较为准确的相图和有关信息。

On the basis of analysis of developing background and theory of thermoelectric graded materials, p-type (Bi1-0.85Sb0.85)Te3 and PbTe two segments thermoelectrical graded materials with different barriers were fabricated by conventional hot-pressing process.

在分析了热电材料的发展背景和研究理论的基础上，采用热压法制备出单体和双层具有不同扩散势垒的1-0.850.8与PbTe体系二元梯度热电材料。

This paper deals with the best experimebtal condition of the determinationof the hardness of water by spectrophotometry with Methyl Thymol Blue Complexon as chlorophosphosphonsazo, and the concrete formula of Lambert-Beer's Law inthe mixed system of Ca-MTB is calculated.

研究了以甲基百里香酚兰络合剂为显色剂，用分光光度法测定水硬度的最佳试验条件，导出了朗伯─比尔定律在Ca—MTB与Mg—MTB二元混合体系中的具体形式。

The joint toxicity was evaluated by different methods, including toxicity unit,additive index, similarity parameter and mixtures toxicity index. The results show that the binary joint effects of phenol and toluol mixed with SDS are synergistic, while the binary joint effect of SDS and nitrobenzene is antagonistic. The environment risk of some compounds will be enhanced because of the joint of SDS.

研究结果表明： 4种不同的评价方法对SDS与取代芳烃苯酚、甲苯和硝基苯的联合效应评价结果具有较好的一致性，即SDS与苯酚、甲苯的二元混合体系的毒性表现为不同程度的协同作用，而与硝基苯则表现为弱拮抗作用；对环境存在风险性的阴离子表面活性剂SDS，当与一些有毒有害物质共存时会增加该类物质的环境风险性。

With existence of a nonionic surfactant FAA,polyethylene glycol/surfactant complex exhibited good inhibition on clay minerals,despite it was a binary or trinary complex.

PEG和非离子表面活性剂FAA均具有较强的防膨作用，PEG/FAA二元复配体系对黏土的防膨作用优于其单一组分，说明FAA与PEG在防膨作用方面具有协同效应。

We study the phase-separation and microstructure of the pure binary and trinary mixed LB and LS films of Dimyristoyl phosphatidyicholine cholesteroland sphingomylin deposited from pure water subphase by π-A isotherms and tapping mode Atomic Force Microscopy.

在本章中我们用这种极易溶于水的阳离子型聚合物PEI为一软垫，研究以此软垫为基底的不同生物分子和它们不同种二元及三元混合单分子膜体系在含PEI亚相上的相结构情况，初步的讨论了它们以云母为基底的IS膜和LB膜的微结构或者说是该软垫对单分子膜微结构的影响。

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。
