The result of the experiment showed that the qualitative medium - speed filter paper can be used as the material of the nitrite - detecting paper: color developing reagent A containing 4 - aminobenzene sulfonamide and N - 1 naphthyl ethylenediamine hydrochloride, and mixtures of 1 : 1 naphthylamine solution and sulfanilic acid solution as color developing reagent.

实验结果表明：定性中速滤纸可以作为亚硝酸根试纸的材料；含有4-氨基苯磺酰胺和N-1-萘基乙二胺盐酸盐的显色剂A及含有1：1的α-萘胺溶液和对氨基苯磺酸溶液的显色剂B，按1：1混合后可以作为显色剂；通过应用实验表明，亚硝酸根试纸具有体积小、便于携带、检测方便、成本低廉等特点。

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.
