化学成分，化学成分 GB/T5231—2001中的 H65化学成分范围，为使其性能更有保障，对主成分及有害杂质进行更严格控制，制订企业标准（Q/JY001—2004）。（2）公差及机械性能参照 GB/T1527—2006拉制管标准和浙江三花集团企业标准 Q/ZSH05·099—2002，制订企业标准（Q/JY001—2004），对其进行严格控制。三位四通阀的工作环境是液态或汽化的氟利昂等冷凝剂，其内腔气密性要求十分苛刻，这就需要 AC 黄铜管的内、外表面质量有极高表面质量，内、外表面光洁，无划伤、拉痕、起皮、沙眼、夹杂等加工缺陷，无酸、油、润滑等残留附着物。由于 AC 黄铜管在制作四通阀时，需要锯切、车削、冲孔等机加工，因此对公差精度要求很高。

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。
