It is found that the surface of Nafion membrane can be rendered more hydrophilic by modification with sulfonic type PFSAS.

在各种类型PFSAS中，只有阴离子型FC-99能有效持久地改善Nafion膜表面的亲水性，而不引起膜的显著溶胀，特别是经FC-99的碱性液处理后膜的表面改性效果更好。

The welted joint , executed in this way, is a rapid means of joint ing and effectively allows for expansion and contraction of the metal covering.

这种新方法需要一种专门的高效率的机械装置。对接坡口焊是一种连接迅速的施焊工艺，它可以有效地保证金属盖板的胀缩。

The above result can also be proved by the test of equilibrated dissolution and swell ofcross-linked polymer in dimethyl benzene at 70℃and boiled benzene.

在70℃的二甲苯和沸腾的苯中进行交联物的平衡溶胀试验，也可以证明当凝胶含量相同时，硅烷交联聚乙烯的交联密度大于过氧化物交联聚乙烯。

The influences of drug entrapment efficiency and drug release properties were investigated. Everted sac experiments were carried out using viable segments of rat intestine for comparing mucoadhesive characters.

利用大鼠肠囊外翻实验对凝胶小球的生物黏附性能进行比较，通过对释放机理的探讨和凝胶小球溶胀性的测定进一步证明2种凝胶小球释药行为的不同。

In order to unsterdand the properties of rebound and recompression, this study carried out oedometer tests for six soft clays with three surcharge ratios to simulate surcharging. Properties analyzed in this thesis include: 1 post–surcharge secant secondary compression index; 2 amended post- surcharge secant secondary compression index in which the time starts from load application; 3 time at which secondary compression reappears; 4 post-surcharge secondary compression strain rate.

为探讨软弱粘土於超载移除后的回胀与再压缩性质，本研究利用传统单向度压密试验仪对六种土样分别进行三种超载比的超载单向度压密试验，并分析所得结果，分析方法包括：1评估后超载割线二次压缩指数；2评估修正后超载割线二次压缩指数，将后超载的时间原点改为由加载起始时起算；3评估二次压缩再现时间与超载比的关系；4评估后超载二次压缩应变速率之特性。

The formulation of JG3 synthetic automobile brake oil is explained. It is verified bytest that this product offers super vapour -- lock resistance under high temperature, good lowtemperature fluidity, corrosion resistance, and rubber gasket non -- solvency . The formula canmeet GB10380--89 standard and the bench tester requirement.

叙述了 JG3合成汽车制动液的配方研制过程，试验证明，该产品具有优良的高温抗气阻性、良好的低温流动性、抗腐蚀性，以及对橡胶皮碗的不溶胀性，该配方已达到GB10830—89标准及台架试验要求。

First, pre-heating the preform; then stretching it with stretch-rod meanwhile blowing it so that the preform becomes the real shape of mold of the bottle; finally, cooling the product and taking it out mold.

本课题所论述的PP瓶的拉伸吹塑成型是采用二步法，即成型好的瓶坯先预热，后用拉伸杆拉伸型坯并通入压缩空气吹胀型坯使之贴紧模具型腔，把模腔的形状与尺寸赋予制品，然后冷却最后脱模。

The results showed that adhensive agents in different kind and different mixture ratio could decrease negative electrode gas evolution,and its effects on discharge performance of battery were also different.

通常这两种作用是相关的，要保持对锌粉的良好分散作用和对碱液的良好吸收作用，要求粘合剂在溶胀后具有丰富的网络结构。

The results show that in the 1.0 mol/L sulphuric acid solution, the rates of swelling and breakage of emulsion liquid membrane decline and the extraction efficiency is 99.4%.

结果表明：在1.0 mol/L的硫酸含铬废液中，该体系具有良好的稳定性，液膜的溶胀率以及破损率明显降低，Cr的萃取率高达99.4%。

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。
