通过水槽和水洞的实验，研究了超疏水性表面在不同流动条件下的减阻特性。
The last, through experiments of flume and water tunnel, the liquid slip effect on drag-reduction over super -hydrophobic surface for various flow conditions was researched.
一般情况下，超疏水表面可以通过两种方法来制备：在疏水性表面构建粗糙结构或者在粗糙表面修饰低表面能物质。
One is to create a rough structure on a hydrophobic surface, and the other is to modify a rough surface by materials with low surface free energy.
并根据“荷叶自洁效应”的仿生学原理，利用超微粉在涂层表面构造粗糙结构，提高其疏水性。
According to the theory of bionics and powders was used to build a coarse structure onto the surface of the coating, and the hydrophobicity was highly improved.
