The desulfurizers (cyclobutyl sulfone and diisopropanolamine) have poisonousness. If the sweetening solution foamed seriously that can't be used, sweetening solution's discharge will affect environment.

脱硫溶液严重发泡后将不能再使用，且脱硫溶剂环丁砜和二异丙醇胺都具有毒性，脱硫溶液的排放将会对环境安全造成严重地影响。

Among pathogens , the most common pathogens associated with VAP were Pseudomonas aeruginosa ( 3013 %), Acinetobacter baumanii (1115 %), Klebsiella pneumoniae ( 1017 %), Escherichia coli ( 716 %) and S taphylococcus aureus ( 618 %). Their multiple drug2resistance to antibiotics was serious. Drug sensitivity tests indicated that the GNB had lower drug2 resistance to such antibiotics as imipenem , amikacin , piperacillin/ tazobactam , ceftazidime , cefepime , cefoperazone/sulbactam , ciprofloxacin and ticarcillin/ clavulanate. Polymicrobial pathogens were more isolated in late2onset VAP than in early2onset VAP.

Therefore, in the laboratory, a 2L gasliquid equilibrium measurement device was used to measure the equilibrium solubility of H2S, CO2, CH3SH and COS in the mixed solutions of Methyldiethanolamine, Tetramethylene sulfone respectively under different temperatures and different proportions. With the relevant parameters being correlated from the measured data, a corresponding thermodynamic calculation model was set up, based on the gasliquid two phase state equilibrium equation, and in combination with the overseas research results.

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.
