v50

And anti-bullet property ( V50 and SEA ) advances with composites thickness increasing .

并且随着复合材料厚度的增加，其抗弹性能（V50值与SEA值）也将有不同程度的提高。

There is little difference between V50 and V25 no matter in acute-outbreak period or catabatic period ( P > 0.05 ) .

V25在急性发作期与缓解期相比较均差异无显著性（P＞0.05）。

The critical flashover voltage ( V50 ) and standard deviation (δ) obtained by least square method and the method of weighted mean are not the best value fitted to the flashover probability data .

指出用这两种方法得到的百分之五十放电电压和标准偏差所代表的正态分布，并不是适合于试验数据的最佳分布；

In the range of incident velocities near to the perforation limit ve-locity ( V50 ) , this mechanism depends on thickness and interlaminar shear strength of composite plate .

在接近穿孔极限速度的入射速度（V50）范围内，这一机制依赖于复合材料板的厚度和中间层剪切强度。

FVC 、 FEV1.0 、 V50 increased after the inhalation , which suggest that vitamine K3 decreased bronchial high reactiveness and improve lung function in asthma patient .

肺功能指标FVC、FEV1。V（50）等提高，提示吸入维生素K3可降低气道高反应性，改善肺通气功能。

The main lung function impairment in GERD is the increment of the small airway resistance , which could be reflected by the most sensitive indexes V25 % and V50 % . And most of patients ' respiratory symptoms are nocturnal .

根据我们临床观测发现夜间发作与小气道损伤（V25%、V50%为反映小气道损伤最敏感的肺功能指标）为主的特点。
