collapsible tube

基本解釋

The emphasis of the project was laid on the effect between collapsible tube and viscous flow in bifurcating airways.
重點(diǎn)考察分叉結(jié)構(gòu)中可塌陷管和不同雷諾數(shù)流動(dòng)之間的相互影響。
By using finite element analysis (FEA) code, numerical simulation on axial compression critical load of collapsible lenticular tube is conducted to verify design indexes.
采用有限元法進(jìn)行了軸向壓縮承載能力分析計(jì)算，驗(yàn)證了制件可以滿足設(shè)計(jì)指標(biāo)要求；

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，當(dāng)管流速度幅值超過臨界速度時(shí)，會(huì)產(chǎn)生失穩(wěn)和位移振蕩。

It flies too fast to be hand-launched, so it ejects out of a thin tube with collapsible legs that a soldier can set up in an instant.
