HP3 identified as Zoogloea sp. is an effectively strain. Under the optimal degradation condition and ABAS concentration of 200～1200mg/L, the ABAS degradation followed negative exponential model. With the ABAS concentration increasing, the ABAS degradation was greatly regressed. Temperature was the most important factor influencing ABAS degradation. The functions of specific growth rate and temperature, degradation rate of ABAS and temperature were constructed respectively.

第二部分，我们研究了α，α-二氟苄基卤类化合物的亚磺化脱卤反应、产物的转化及全氟烷基亚磺酸盐与芳环化合物的全氟烷基化反应，发现全氟苄基碘或溴及α，α一二氟苄基溴在保险粉等亚磺化脱卤试剂引发下可生成相应的亚磺酸盐；全氟苄基亚磺酸盐与氯气或溴反应可生成全氟苄基磺酰氯或磺酰溴；在烯烃存在下，全氟苄基碘则与烯烃发生加成反应，生成相应的1：1加成产物；在三价醋酸锰的作用下，部分芳香化合物如茴香醚，二甲氧基苯，吡啶，喹啉等可以和过量的全氟烷基亚磺酸盐发生双全氟烷基化反应，反应表现出一定的区域选择性，产率良好。

Within the range of 200mg/L—1000mg/L, the more the initial concentrations of ABA, the more the decolorize velocity of it. The functional relationships between specific growth rate of N1 and temperature, degradation rate of ABA and temperature were constructed, respectively.

通过测定菌株的生长曲线和降解曲线，表明N1菌株的菌体生长和溴氨酸的降解过程是同步进行的；N1菌株对溴氨酸的脱色作用是酶促降解反应的结果，脱色酶需经溴氨酸诱导产生；在一定浓度范围内（200mg/L—1000mg/L），随着溴氨酸浓度的增加，其脱色速度逐渐变慢。

Due to N-N bond weakest, nitrosamines are denitrosated by HBr/HOAc to release nitrogen oxide, which can be oxidized to form NO〓. Trapped in sulphanilamide and N-1naphthylethylene diamine di-HCl solution, the NO〓 transforms into NO〓 and develops color in the solution.

该法根据亚硝基官能团中N-NO键的键能最低，采用氢溴酸/醋酸溶液选择性断裂N-N键，对逸出的NO通过氧化成为NO〓然后用显色剂吸收，再由分光光度计测量吸光度并计算出亚硝胺含量。

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.
