reverse transition meaning in English

由水平飞行向垂直飞行过渡

Turbulence ; reverse transition ; drag reducing
湍流逆转捩减阻
Experimental research on the mechanism of reverse transition in turbulent boundary layer
湍流边界层逆转捩机制的实验研究
Phenomenon of reverse transition on a heated flat plane with stable temperature stratification
加热平板表面温度分层产生的湍流逆转捩现象
In the twodimensional wind tunnel , systematic experimental researches were carried out on the phenomenon of reverse transition on a heated plane with stable density stratification
针对加热平板表面密度分层结构中的逆转捩现象，在二元风洞中进行了系统的实验研究。
All of the results indicated the turbulent boundary layer had been turned into the laminar layer . the skin friction coefficient drops rapidly . this result not only proved the phenomenon of reverse transition had occurred , but also showed that this condition was drag - reducing condition
实验结果表明板面附近的流动已由湍流流动转变为层流流动，同时平板表面的摩擦系数较没有温度梯度时有大幅度下降，不仅证明了边界层逆转捩现象的存在，也说明了这种条件起到了减阻的效果。
