At present, the dualization social security system has seriously already hindered the further development of the urban and rural economy of China, so it is imperative to reform dualized social security system and to combine the system in rural and urban areas.

目前，社会保障体系的二元化已严重阻碍了我国城乡经济的进一步发展，改革二元化的社会保障制度，实现城乡整合已势在必行。

Equilibrium constant of salts for (liquid +solid) equilibrium at 288 K were evaluated with Pitzer"s model. The solubilities of quaternary and quinary system were calculated by Pitzer "s equations. The prediction results were in agreement with the experimental results essentially.

用288K时二元及三元体系的溶解度数据，运用多元线性回归的方法拟合了PitZer方程中288K时该五元体系所涉及各盐的单盐参数及混合参数；计算出了各盐288K时溶解平衡常数，运用PitZer方程对四元及五元稳定体系相平衡进行了理论模拟，计算结果基本令人满意。

After seriously analyzing the system of Marxism Intercourse Theory in detail, the author makes the contemporary reading on Marxism Intercourse Theory, which breaks through the traditional duality method (it holds Marxism Intercourse Theory is the intercourse based on physical/spirituous or the relation of male/female),then puts forward Marxism Intercourse Theory represents four constituents in the period of globalization, that is economy intercourse, political intercourse, cultural intercourse and social intercourse, among which economy intercourse is the base and core, political and cultural intercourse play the important role to economy intercourse, and social intercourse is the final purpose of all intercourse. From above the thesis give prominence to the contemporary significance of Marxism Intercourse Theory.

在对马克思交往理论体系进行认真、详细的分析之后，认为我们以前对马克思交往理论所进行的二元划分并不能全面反映现阶段经济全球化时期的交往形式与过程(二元划分结构认为马克思交往理论体系就是物质交往与精神交往以及建立在男女关系之上的两性交往)，因此，我进行了对马克思交往理论的当代解读，认为马克思交往理论在全球化时期表现为四大组成部分：经济交往、政治交往、文化交往和社会交往。

ZHOU Zhangjian（Laboratory of Special Ceramics and Powder Metallurgy, USTBeijing, Beijing, 100083, China）Abstract:On the basis of analysisof developing background and theory of thermoelectric graded materials, p-type (Bi1-0.85Sb0.85)2Te3and PbTe two segments thermoelectrical graded materials with different barriers werefabricated by conventional hot-pressing process.

具有不同扩散势垒的p型(Bi1-0.85Sb0.85)2Te3和PbTe二元梯度热电材料的研制徐桂英葛昌纯高艳平周张健摘要：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(Bi1-0.85Sb0.85)2Te3与PbTe体系二元梯度热电材料。

Both the scattering and rheological results indicated that the phenomenon similar to"double cloud point", which has been found along the vorticity direction by previous studies, could be also observed in the velocity direction, which confirms the prediction of the above theory that the polymer blend will exhibit anisotropical complex phase diagram under shear. It's also found that the mixing along vorticity direction was reduced by weak shear but enhanced by strong shear. In addition, the more remarkable the molecular weight differences between components, the more prominent the shift of the apparent phase boundary along vorticity direction.

除了以往研究发现涡流方向存在&双浊点&现象以外在，本文的光散射和流变测试均显示，剪切场下体系在流动方向上也出现了类似&双浊点&的现象，证实了上述理论模型关于剪切场会导致二元高聚物共混体系出现各向异性的复杂表观相图（例如Miscibility Gap现象）的预测；同时发现弱剪切会导致体系涡流方向上的相容性减小，而强剪切则在该方向上增强相容性；另外，两组分分子量的差异越大，表观相界的移动越显著。

The results indicated that both binary interactive parameters of water/isobutanol system from this work and the parameters of water/ethanol from literature can be used to precdict the liquid-liquid equilibria of water/ethanol/isobutanol. But the parameters of ethanol/isobutanol from the literature were not appropriate for the prediction. Furthermore, the model parameters from 30℃ can can be used to predict the liquid-liquid equilibria under 35 ℃. The model parameters of water/isobutanol are independent on the temperatures, so constant parameters irrelative to temperature can meet prediction accuracy. Othmer-Tobias/Bancroft equation was also used to fit the liquid-liquid data of water/ethanol/isobutanol system, but it didnt possess the performance of predicting the liquid-liquid equilibria.The partition coefficients of dipotassium glycyrrhizinat were determined in the liquid-liquid two-phase system of water/ethanol/isobutanol and corrected by experiential equation.

结果表明：由本文的二元液液相平衡实验数据关联得到的水+异丁醇体系的相互作用参数和文献上由二元气液相平衡数据关联得到的水+乙醇体系的相互作用参数都具有预测三元液液相平衡关系的能力，而文献上由二元气液相平衡数据关联得到的乙醇+异丁醇体系的相互作用参数不具有预测三元液液相平衡关系的能力；可以用从30℃三元液液相平衡数据关联回归得到的模型参数来预测35℃时的液液相平衡关系；水+异丁醇的相互作用参数与温度关系不是很密切，计算时取与温度无关的常数即能满足关联精度要求；Othmer-Tobias和Bancroft经验方程可用于水+乙醇+异丁醇两相体系的液液相平衡关系的关联计算，但这类经验方法并不具有预测能力。

But our country's present social security system actually has the hindrance function to the occupation mobility, the main performances are as follows: Two units social security system, the unequal tax revenue system in the social security, social security singleness in view of the impoverished social class, hardly carried and transferred characteristics of social security system , ignoring benefits protection of mobile staffs, lack of social security legislation , slow development of service system of social security ,lack of policies and measures on promoting regional motilities insocial security system.

但是，我国现行的社会保障制度却对职业流动有着一定的阻碍作用，主要表现为：二元的社会保障体系的存在，社会保障体系的便携性、可转移性较差，忽视流动职工的利益保护，社会保障立法的缺失，社会保障服务体系发展缓慢，社会保障中税收体系的不平等，针对贫困阶层的社会保障单一，社会保障体系缺少促进区域流动的政策与措施等方面。

Generally speaking, there are three representative systems proposed by scholars: monistic system, dualistic system and triple system.

总的来说，学者们所提出的归责原则体系比较有代表性的有三种：一元归责体系、二元归责体系和三元归责体系。

The dynamic adsorption of Congo red and Cu(superscript 2+) still follow the second-order kinetics.

二元体系中，壳聚糖对Cu(上标 2+)表现出更高的亲和力和选择性，且二者的吸附动力学仍符合伪2级动力学模型。

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。
