Modification of fluorocarbon resin 246 (Copolymer of vinylidene fluoride－tetrafluoroethylene－hexafluoropropylene) with epoxy resin will improve the adhesion of fluorocarbon resin on metal surface.

摘 要：用环氧树脂改性偏二氟乙烯－四氟乙烯－六氟丙烯共聚物(氟树脂246)，可以大大提高氟树脂在金属底材表面的附著力。

It was found that ARA was composed of esterification products of (2-HEA)-ester with pimaric acid, dehydroabietic acid, abietic acid and two isomers of acrylpimaric acid. ARA is a good crosslinking agent which can copolymerize with most vinyl monomers. The properties of solvent-resistance and heat resistance of the copolymer were improved considerably by the use of ARA.

实验结果表明：ARA主要由海松酸、脱氢枞酸、枞酸和丙烯海松酸的二种异构体的丙烯酸－2-羟基乙基酯的酯化产物组成，ARA是一种良好的交联剂，可与大多数乙烯基单体共聚合，其与MMA的共聚物的耐溶剂性和耐热性均得到了较大幅度的提高。

In this thesis, monomer with unsaturated double bond was firstly synthesized byreacting acryloyl chloride with bifunctional monomer. Such synthesized monomer ormonomer with initial unsaturated double bond was used to prepare linear polymericmaterials by free radical polymerization. A series of new degradable space polymerswith acylamino bond were subsequently synthesized using diisocyanate as thecross-linker.

本文首先通过丙烯酰氯和双官能团单体反应引入不饱和双键，或者直接使用具有不饱和双键的单体，通过自由基聚合得到含有活泼羟基或氨基的线型高分子聚合物，再用二异氰酸酯作为交联剂交联，从而合成了一系列基于酰胺键的新型可降解高分子体型聚合物。

In this study, collagen connected titanium plates were evaluated in vitro. The titanium plates were treated by glow discharge with allylamine.

钛金属表面先以丙烯胺电浆处理，使附著上胺基(-NH2)，再分别以不同浓度的交链剂BS3及戊二醛连接固定第一型胶原蛋白。

The deposition thickness of allylamine was increased with the treating time. The surface textures were changed following different procedures except allylamine groups and it means that the 30 min deposition thickness of allylamine is too thin to change the surface contours.

SEM-EDS的结果显示在未经任何处理及经氩气电浆清洁后的钛金属表面，侦测到主要为钛元素，丙烯胺电浆处理后，即可测到氮元素；戊二醛作用后表面有氧元素的出现；白蛋白处理后即可测得碳及氧元素。

Otherwise, an intermediary allylamine deposition was covalently linked to the oxide layer by glow discharge, the covalent binding of bioactive protein to the free terminal NH2 groups using glutaraldehyde as a coupling agent was followed.

并利用丙烯胺的电浆处理在钛金属表面键结上胺基(-NH2)的官能基，之后再以交链剂戊二醛来固定生物活性胶原蛋白於低温电浆处理后的钛金属表面。

The second layer (10) comprises: 100 parts by weight of an acrylonitrile-butadiene rubber, said acrylonitrile rubber comprising from 20 to 65 percent by weight of bound acrylonitrile; from 3 to 20 parts by weight, per 100 parts by weight of the NBR, of at least one acid acceptor; from 1 to 10 parts by weight, per 100 parts by weight of the NBR, of at least one organophosphonium salt; and from 0.25 to 10 parts by weight, per 100 parts by weight of the NBR, of at least one amidine.

公开的是一种包含直接相互接触的第一层与第二层的软管；第一层包含从四氟乙烯、六氟丙烯、偏二氟乙烯、和全氟乙烯醚衍生的一种热塑性四元共聚物；第二层包含100重量份丙烯腈丁二烯橡胶，所述丙烯腈橡胶包含约20～约65wt％结合丙烯腈；每100重量份NBR约3～约20重量份至少一种酸受体；每100重量份NBR约1～约10重量份至少一种有机盐；和每100重量份NBR约0.25～约10重量份至少一种脒。

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。
