The chemical composition of th essential oil from Illicium verum Hook.f.was determined by the means of GC-MS.

采用GC-MS对八角茴香挥发油的化学成分进行分析，其中反式茴香醚的含量最高。

The rapid increase of desflurane concentration resulted in coughing（60%）, laryngospasm （ 52%）, and significant increments of MAP and HR during induction in D group.

相反，R组很少发生咳嗽和喉痉挛，MAP和HR升高不显著。D组的MACEI50值为2.1 0.4MAC，静泣瑞芬太尼后地氟醚的MACEI50值降至0.9 0.2MAG。

Previous work has suggested that nicotinic inhibitioncould mediate the pronociceptive action of isoflurane.

以前的研究提示，胆碱能抑制剂可以调节异氟醚的早期痛觉作用。

The reaction with propargyl sulfide gave a mixture of allenic sulfide and furan.The former is the [2,3]-sigmatropic rearrangement product,while the latter is derived from the furt...
