The characteristic parameters of fluid during the transition in boundary layer are obviously different from that of the laminar flow or the turbulent flow.

边界层转捩流动的特征参数明显不同于层流或湍流，转捩流动的这些特征直接影响着流体的动力、传热特性。

When flow rate increases, the flow state in honeycomb hole turns from laminar to turbulent, so it can not always be simplified as incompressible laminar flow;

在载体蜂窝孔内随着空速的增加气流状态由层流向紊流转变，因此不能简单地将其气流简化为不可压层流；

Laminar flow hood with an external fan mounted, side mounted fans to upload and fans of three, the installation methods are hanging, floor and mobile are three.

层流罩有风机外接装、风机上装和风机旁装三种，安装方式有悬挂式、落地式和移动式三种。

Darcy's law has achieved vast application as a basic law in problems of fluid flow through porous media. It, however, only holds for cases of linear, laminar flow.

达西定律作为渗流力学的一项基本规律，曾得到广泛的应用，但它只适用于线性的层流情况。

The result shows that the rheological model of paste-like slurry is similar to that of Binhan and its flow state in pipeline transportation is of laminar flow type.

结果表明，似膏体料浆在较高浓度近似呈宾汉塑性体，在管道中的流态属于层流。
