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。

According to experiment processes and SEM photographs of the best polymer, pure polyacrylates emulsiods were destroyed during preparation and lumps caused by self-cohesive action were formed and difficult to break up, which the co-polymers emulsiods from partially neutralized acrylic acid and acryl amide forming into unconsolidated bulkload were undivided.

通过SEM照片我们发现，纯的聚丙烯酸盐高吸水性树脂乳胶粒在沉淀洗涤的过程中由于自粘结作用大部分被破坏了，形成难以破坏的块状物，而部分中和的丙烯酸-丙烯酰胺共聚物高吸水性树脂的乳胶粒完整无缺，形成较为松散的粒状物。

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.
