For developing an immunoassay for multiple residues of pyrethroid pesticides, the hapten N-2- carbanmoyl-(3"-phenoxyphenyl) methyl 3-(2"-Cldoro-3",3",3"-trifluoropropenyl)-2, 2-dimethylcyclopropane- carboxylate was synthesized from cyanohydrin and 3-(2"-Chloro-3",3",3- trifluoropropenyl)-2, 2-dimethylcyclopropanecarboxylic acid via hydrolysis and esterification. The synthesis of the hapten was foundation of preparaing anti- cyhalothrin polyclonal antibodies.

为了制备对单一拟除虫菊酯高特异性的抗体，以菊酸和氰醇为起始原料，通过水解、酯化反应合成了半抗原N-2-氨甲酰-(3-苯氧基苄基)甲基-3-(2-氯-3，3，3-三氟丙烯基)-2，2-二甲基环丙烷羧酸酯，为进一步制备抗三氟氰菊酯的特异性抗体奠定基础。

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.
