加上叔丁胺在医药、农药、染料等行业中的应用量，预计到2007年，国内叔丁胺的需求量将达到1万吨左右。

The intercalation of ethylamine, butylamine, hexylamine and octylamine is more facile than that of dodecylamine and hexadecylamine, and the layered structure of the former intercalates is more ordered displaying a more intense and symmetrical (001) peak in their XRD patterns.

在直链的烷基胺中，乙胺、丁胺、己胺和辛胺较易嵌入层间，嵌入物的(001)峰均很强，并有明显的(002)峰出现，表明得到的嵌入物层状结构较规整。

objective to study the infection and sensitivity to antimicrobial agents of staphylococcus of bacterial prostatitis patients.methods the results of bacteriology and drug susceptibility of 421 patients,who were suffered from prostatitis,were analysed retrospectively.results in the 421 succus prostaticus samples,278 strains pathogenic microorganisms of 15 genera were isolated from the 273 succus prostaticus samples,and the major pathogenic microorganisms was staphylococcus aureus(57.2%) and coagulase negative staphylocous（17.3%.the drug resistance rate of staphylococcus to penicilling,erythromycin and albomycin was 88%-97%,and it was 33%-50% to fluoroquinolones.the drug resistance rate of staphylococcus to amikacin,cefazolin,nemycin,rifampicin and cefoperazone was lower than 30%,and they all appeared susceptible to vancomycin.conclusion staphylococcus is the main germ of bacterial prostatitis and it appears high drug resistance to usual antibacterials.staphylococcus is susceptible to vancomycin,amikacin,cefazolin,neomycin,rifampicin and cefoperazone.

目的 探讨细菌性前列腺炎患者葡萄球菌的感染状况及抗菌药物敏感性。方法回顾分析421例前列腺炎患者标本的细菌学和药物敏感性试验结果。结果 421例前列腺液标本，273例分离出细菌，共分离出15个种别共计278株病原菌，其中金黄色葡萄球菌占57.2%，凝固酶阴性葡萄球菌占17.3%；葡萄球菌对青霉素g、红霉素、白霉素耐药率为88%～97%，对氟喹诺酮类耐药率为33%～50%，对丁胺卡那霉素、头孢唑啉、新霉素、利福平和头孢哌酮耐药率均0%，对万古霉素全部显示敏感。结论葡萄球菌是细菌性前列腺炎的最常见病原菌，对临床常用抗菌药物具有较高的耐药性，葡萄球菌对万古霉素、丁胺卡那霉素、头孢唑啉、新霉素、利福平和头孢哌酮较为敏感。

Cases in the control group were treated with salbutamol based on the routine treatment.

将95例毛细支气管炎患儿随机分为两组，对照组95例在常规治疗基础上加用沙丁胺醇，治疗组95例在常规治疗基础上加用沙丁胺醇、异丙托溴铵、布地奈德，均2次/d空气压缩雾化泵吸入，观察两组临床症状、体征改善情况。

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。
