In the paper, new type of polyurethane ionomers containing carboxyl in soft segments was synthesized with IPDI, DMBA, carboxylated polycaprolactone etc.

本文利用一种新型的聚己内酯、异佛尔酮二异氰酸酯、二羟甲基丁酸等合成了软段含有羧基的聚氨酯离聚体。

Polyols can be divided into latex polyol and dispersion polyolaccording to the way of preparation. In this paper, acrylic latex polyol and acrylic dispersionpolyol were synthesized respectively. One kind waterborne polyisocyanate, which was waterbornehexamethylenediisocyanate trimer, was obtained by hydrophilic modification. Andisophorone diisocyanate trimer (T1890E), which can formulate into 2K-WPU coatings withpolyols, was selected from the unmodified polyisocyanates.

本文合成了两种羟基组分：丙烯酸乳胶多元醇和丙烯酸分散体多元醇，亲水改性得到了一种水性多异氰酸酯组分：水性六亚甲基二异氰酸酯三聚体，同时在未改性的多异氰酸酯组分中遴选了一种多异氰酸酯：异佛尔酮二异氰酸酯三聚体(T1890E)，可用来组成双组分水性聚氨酯涂料。

The results show that the sample capacity of the solgel PDMS column is much higher than that of the conventional PDMS column.

实验结果表明溶胶凝胶聚二甲基硅氧烷柱的柱容量远高于传统聚二甲基硅氧烷柱的柱容量。

It is found that the density of sinters is better when the temperature raise. The conductivities of sinter by addition of 5% polyethylene glycol than that of 1% polyethylene glycol.

结果表明：当烧结温度提高时，陶瓷样品的致密度提高，添加5%聚乙二醇制备的陶瓷样品的电性能比添加1%聚乙二醇制备的陶瓷样品高。

OBJECTIVE: To evaluate use of peginterferon-alpha2a plus ribavirin to re-treat nonresponders to peginterferon-alpha2b plus ribavirin.

目的：评价聚乙二醇干扰素α-2b联合利巴韦林治疗无应答的患者接受聚乙二醇干扰素α-2a联合利巴韦林再治疗。

3Based the trait of the vegetable gum drilling and completion fluid, used LV-CMC,FJ-03, polyglycol, JL-α and SMP-Ⅰas the filtration control agents which should be optimized. Finally this paper optimized LV-CMC and polyglycol as the filtration control agents. In order to form a tough impermeable cake, this paper used QS-2 as the inflexible filling material according to the mechanism of fluid loss control.

根据植物胶钻井液完井液的特点，确定LV-CMC、FJ-03、聚乙二醇、JL-α、SMP-Ⅰ为降滤失剂的优选对象，通过实验优选出LV-CMC、聚乙二醇为植物胶钻井液完井液体系的降滤失剂，并根据钻井液的降滤失机理，为使形成更加坚韧致密的泥饼，确定QS-2作为刚性填充粒子。

The ultrathin multilayer film of poly (diallyldimethylammonium chloride) and polyvinylidene fluoride has been prepared by the layer-by-layer static self-assembly method. The PVDF/PDDA multilayer film with the thickness ranging from about 30nm to 150 nm the thickness of each layer is about 9nm.

聚二烯丙基二甲基氯化铵和极化处理后的聚偏氟乙烯复合超薄膜是通过层与层的静电自组装方法制备的，厚度约30～150 nm，每层膜厚度约为9 nm。

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。
