方法应用YHL型智能测氧仪监测呼吸机排气管路连接方式改进前后舱内氧体积分数变化。

The increase of PMAM expression is one of the important pathological features of cerebral infarction in rats, and YHT can inhibit the activation of platelet by decreasing the expression of PMAM.

血小板膜粘附分子表达增高是脑梗塞的重要病理特征之一，益气活血片可能通过降低血小板膜粘附分子的表达，从而抑制血小板活化。

[ Results] The expression of PMAM were increased in cerebral infarction groups and YHT could decrease PMAM expression ( P < 0.01 as compared with that in normal control group).

[结果]脑梗塞大鼠模型血小板膜粘附分子的表达较正常组为高（P<0.01）.而益气活血片能明显降低其表达（P<0.01）。

The YHT contains yeast that was harvested from the cylindroconical tank ( CCT).

酵母储罐中的酵母是从发酵罐中回收得到的。

目的观察治疗性乙型肝炎（乙肝）疫苗（重组乙肝表面抗原和高效价抗乙肝免疫球蛋白组成的免疫复合物，简称乙肝疫苗）Ⅰ期临床研究中诱生的免疫应答作用。

In the semantics and the pragmatics," Yigai" and "Yil ü" are suitable in all, with no exception," Yil ü" mainly expresses subjective stipulation, whereas," Yigai" mainly expresses objective statement.

在语义和语用上，一概和一律都表示适用于全体，没有例外，一律主要表示主观规定性，而一概主要表示客观陈述性。
