expiratory time

Expiratory time for normal children was 1.74 ± 0.62S , of which 7 cases ( 4.5 % ) had an expiratory time of less than 1s . The parameters of pulmonary function all increased with age ( P 0.01 ) .

正常儿童的呼气时间为1.74±0.62S，其中有7例（4.5%）呼气时间少于1秒。各项肺功能参数均随年龄增长而增加（P均0.01）。

Results : After applying the non-NMDA receptor agonist KA , it was found that the respiratory circle and the expiratory time were lightly lengthened , but the NMDA receptor agonist NMDA had no effect on the RRDA .

结果：使用非NMDA受体激动剂海人酸（KA）后，可见呼吸周期及呼气时间有所延长，NMDA受体激动剂NMDA对呼吸活动则没有明显影响；

The inspiratory and expiratory time , the amplitude and frequency of respiration in model group were increased , but the differences were not significant compared with the control group ( P > 0.05 ) .

吸气相时间和呼气相时间延长，呼吸幅度增加，呼吸频率减慢，但差异均无显著性；

( Results ) After sensitization of 3 weeks and challenge of 3 days , the animals expressed prolonged expiratory time and elevated expiratory pressure in pulmonary function testing compared to those in group N.

结果小鼠致敏3周及激发3d后，肺功能测定表现为呼气相时间明显延长，呼气相最大压力明显增大，与正常对照组比较有显著性差异（P<0.01）；

The continual time and pausal time , the area and amplitude of discharges of the phrenic nerve were measured . The inspiratory and expiratory time , the amplitude and frequency of respiration were also measured .

测量膈神经放电持续时间、间期、放电幅度，测量吸气相时间、呼气相时间、呼吸频率和幅度。
