TAV

TAV in PIH group was significantly lower than that in the control group , especially in the late gestational age ( P < 0.05 ) .

TAV在PIH组显著低于对照组，尤以妊娠晚期为著（P<0.05）。

The parameters of hemodynamics are composed of PSV , EDV , TAV , RI and S / D.

血流特点参数包括，PSV、EDV、TAV、RI和S/D。

The changes of TAV of the ocean are closely related to ENSOevents , the Asian winter monsoon and the tropical atmospheric circulation anomalies .

南海TAV的变化与ENSO事件、东亚冬季风和热带大气环流的变异密切相关。

The method for controlling gains scheduled by the pressure is used to digitally simulate the flight path . Simulation results show that the designing gain parameters are reasonable and meet the TAV scheduled climbing goal .

采用控制增益参数随动压变化进行调参的方法，对爬升段飞行轨迹进行了数字仿真，结果表明设计的控制增益参数及控制律，满足了跨大气层飞行器爬升段的预定目标要求。

Simulating results show that the disturbing airflow between the carrier and vehicle affect the safety of TAV . Reasonable igniting time selection and slow pulling - up maneuver are also important to flight parameters of preliminary phase .

对此进行了分析研究，仿真结果表明分离时刻载机与飞行器之间的干扰气流影响飞行安全；点火时机合理地选择、缓和拉起爬升动作对爬升初始阶段飞行参数稳定合理地变化也很重要；

Results : PI , RI and S / D of the placental bed artery were decreased with increasing gestational age in normal group , while TAV was increased The indices were stable in 30 ~ 34 weeks of gestation ;

结果：正常孕妇随孕龄增加，胎盘床动脉PI，RI，S/D下降，TAV升高，各血流参数值在孕30～34周后趋于稳定；

Phylogenetic analysis of 4 ORFs of PSV-Mi with strains of PSV , CMV and TAV showed that PSV-Mi , PSV-ER and PSV-W form three different evolution branches , which also supports above result .

4个ORFs的系统进化树也表明，PSV-Mi、ER和W株系各自形成独立的进化分枝，进一步证实上述结论。
