1·The emphasis of the project was laid on the effect between collapsible tube and viscous flow in bifurcating airways.

重点考察分叉结构中可塌陷管和不同雷诺数流动之间的相互影响。

2·When the maximum velocity of an oscillated flow in the collapsible tube exceeds the so-called critical velocity, the tube will become unstable and oscillate with displacement.

可坍陷管中，当管流速度幅值超过临界速度时，会产生失稳和位移振荡。

3·It is shown that the thin ply laminate and collapsible lenticular tube meet the function requirements.

研究结果表明，超薄可折叠复合材料豆荚杆满足功能要求。
