黏性流、层流和紊流边界层。
Viscous-fluid flow, laminar and turbulent boundary layers.
在对流层上是平流层，接着是电离层，最上层是外逸层。流体的上流层以下或表面以下的流动。
Above the troposphere is the stratosphere, followed by the ionosphere and capped by the exosphere. a current below the surface of a fluid.
他在对流层、平流层、中间层还是电离层？
Was he in the troposphere, stratosphere, mesosphere or thermosphere?

在对流层-平流层耦合过程中一个重要的系统即为平流层极涡，作为平流层一个强大的绕极涡旋，它的变化是联系对流层和平流层过程的重要纽带。
The strong circumpolar westerly vortex, known as the stratospheric polar vortex is a crucial component in the stratosphere-troposphere coupling system.
由此认为注射充模时，熔体流动层应分为二层：高粘度流动层和低粘度流动层。
The spherulitic diameter varies markedly in the interface. During mold filling process, the flow layer should be divided to two layers: high viscosity molten layer and low viscosity molten layer.
对流层和平流层会吸收太阳辐射吗？
Does the troposphere and stratosphere absorb solar radiation?
这种流动属于层流。
This flow was streamline.
在一个时期，表层和次表层的水流方向相反；表层水流向外海方向流动，靠近底层的水流则向陆地方向流动。
For a time, surface and subsurface current are in opposite directions; flow is seaward at the surface and landward near the bottom.
平流层是从对流层顶向上延伸到50千米高空的界层。
The stratosphere is the layer above the troposphere and extends to about 50 km.
到了夏季，第一对流层顶（极地对流层顶）较少见，基本只有第二对流层顶。
Double tropopause frequency is high in winter, while the first tropopause ( FT)( also called polar tropopause) is rarely seen in summer, in which there is only the second tropopause.

其上是对流层顶，它是对流层的上部边界。
Next comes the tropopause, which is the upper boundary of the troposphere.
