摘　　要：从纳米氟碳涂层及其形成的超疏水表面所具有的特性出发,结合水溶液与超疏水表面接触时形成的不同模型,讨论了超疏水固体表面存在的速度滑移对过冷水的流动状况产生的一系列影响,指出纳米氟碳涂层降低了系统的能耗。The properties of the nano-fluorocarbon coating were introduced and the characteristics of super-hydrophobic surface were analyzed.In order to discuss a series influences caused by the slip velocity in super-hydrophobic surface on super-cooled water flowing,three different mathematical models of super-hydrophobic surface were presented and the results show that nano-fluorocarbon coating can lower the energy consumption of system.
