图为张力性气胸，因呼吸时活瓣样的结构使气体漏入到胸膜腔的越来越多，纵膈移位。

It can test the mechanical properties, such as spline tension, holding tension, tearing, CBR upend, ball upend, Pierce, thickness and so on.
该系统可测试条样拉伸、握持拉伸、撕裂、CBR顶破、圆球顶破、刺破等力学性能。

Allowing for the lower back to be flat this will help us to create the tension that is needed to hit the ball farther than ever.
