The results indicated that hydrogen bond and covalence bond were formed between PVA and TEOS through the sol-gel reaction.

结果表明PVA与无机相发生溶胶-凝胶反应生成氢键和共价键Si-O-Si，形成交联有机聚合物／无机杂化体系，使杂化膜的结晶度减少，控制了膜的溶胀，提高膜的溶解选择性能，但膜的溶胀减少会使通量有所下降。

Dilatancy is a very important property of geotechnical materials, but now there're different definitions about it in geotechnical engineering.

剪胀是岩土材料一个非常重要的特性，但目前对于剪胀的描述并不统一。

However it was found that this theory was not suitable for sand modeling due to the ignorance of internal state variable of materials in the definition of dilatancy equation.

最新的研究表明：由于应力剪胀理论中忽略了土体内部状态参量对剪胀的影响，而使得该理论应用于砂土时发生了困难。

Using this method proposed in this thesis, superplastic free bulging process of duralumin LY12CZ under an external electric field is analysed, both with the constant pressure and with the constant strain rate at the apex.

将此解析—数值混合分析法应用于LY12CZ铝合金在强电场中的超塑性自由胀形过程的数值模拟，其中包括恒定胀形压力和恒定应变速率两种情况。

It has been found that the calcium ion could improve the tensile strength and the encapsulation efficiency of the membranes.

复合膜的溶胀度研究表明，在pH＝11的介质中具有最大的溶胀度。

Now appears a sort of plastic expansion shell bolt,which has strong expansion anchor-hold.

为了解决这一问题，出现了一种具有强胀锚力的塑料胀壳式锚杆。

Champing element was fixed to the column with torque spanner, and it is moved on splined shaft, the transmitted most torque is proportioned with the effective combined area.

用扭矩扳手将胀套装配到圆柱面上，胀套在花健轴上运动，其传递的最大扭矩与有效结合面积成比例。

Considering the problems of spurgear precise plastic forming, such as high deformation resistance, poor flowability and especial hardness to fill cant of gear, technological plan was developed based on precise plastic forming technique, successive control principle and consecutive local deformation theory. Moreover, structures of the rolling preform die and the die with up and down wellrounded forcer for stamping-extrusion and bulge-extrusion combining forming were designed too.

因此本文的主要研究内容和结果如下：本文以某种直齿轮：模数m＝2，齿数z＝20，压力角α＝200，变位系数x＝0为对象，针对直齿轮精密塑性成形变形抗力大，流动性差，特别是成形中齿轮角隅部分更加难以充满问题，基于精密塑性成形技术、逐次控制原理以及连续局部变形原理提出了"直齿轮滚轧制坯－镦挤、胀挤复合精成形"的工艺方案，设计了滚轧制坯的模具结构和上下冲头带圆角的镦挤、胀挤复合精成形的模具结构。

On the basis of the data of subgrade frost heaving observation in Chang-Yu freeway from 2000 to 2002 years,this paper analyzes the factors of temperature,water, soil and subgrade type which influence the subgrade frost heaving.

根据2000—2002年间对吉林省长余高速公路路基冻胀观测所获得的资料，分别分析了温度、水分、土质、路基类型等因素对路基冻胀的影响。

Owing to being lack of uniform freezing temperature and frost heaving tester at present in China, in the paper, the author has developed the freezing temperature and frost-heaving device which introduces computer to gather data.

由于目前国内缺乏统一的冻结温度及冻胀试验装置，本文自行研制了可实现微机数据采集的冻结温度及冻胀试验装置。

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.

另一方面，更重要的是由于城市住房是一种异质性产品。

Climate histogram is the fall that collects place measure calm value, cent serves as cross axle for a few equal interval, the area that the frequency that the value appears according to place is accumulated and becomes will be determined inside each interval, discharge the graph that rise with post, also be called histogram.

气候直方图是将所收集的降水量测定值，分为几个相等的区间作为横轴，并将各区间内所测定值依所出现的次数累积而成的面积，用柱子排起来的图形，也叫做柱状图。
