pressure span

The test conditions and main results of wind tunnel test for Terminal 3 at Beijing Capital Airport are introduced. The block shape coefficients for the most unfavorable conditions are given, which clearly show the characteristics of the wind pressure distributions on this long-span roof surface.

介绍了超大跨度屋盖结构&北京首都机场3号航站楼的模型风洞试验概况和主要结果，给出了屋面在最不利工况下的分块体型系数，清楚地显示了屋面的风压分布特征。

Inspiratory pressure span exhibition chest rise, eyes to watch the direction of the ceiling.

Results: The the physiological index including life span, exploratory behavior, hanging test, crossing stick test, tiltboard test, blood pressure were observed and statistically analysised.

结果：通过观察大鼠生存期，探索行为，悬吊实验，走杆实验，斜板实验，血压变化等指标进行统计分析。

Moreover, the appropriate maximum amplitude is about 5% of span and the total pressure loss at 128% axial chord length can reduce by 4.7%.

成型过程中单峰幅值控制函数要明显优于双峰函数，单峰幅值控制函数中最大幅值约占5%叶高为宜，此时计算结果显示在叶栅128%轴向弦长处总压损失降低了约4.7%。
