Feng和Weinbaum [J. Fluid Mech.422，282（2000）JFLSA 70022 -1120]已经表明，在内皮表面糖萼上滑动的红细胞和在新鲜粉末上滑雪的人之间存在显著的动力学相似性，尽管它们的质量不同。在每种情况下的升力都比经典润滑理论大4个数量级。在这里，我们报告的第一次测量产生的孔隙压力的时间尺度上的滑雪板和显示的可行性设计的火车，可以在轨道上滑行的渗透性和弹性性能是类似于鹅绒。
Feng and Weinbaum [J. Fluid Mech. 422, 282 (2000)JFLSA70022-1120] have shown that there is a remarkable dynamic similarity between a red cell gliding on the endothelial surface glycocalyx and a human snowboarding on fresh powder although they differ in mass by. The lift forces in each case are 4 orders of magnitude greater than classical lubrication theory. Herein we report the first measurements of the pore pressures generated on the time scale of snowboarding and show a feasibility of designing a train that can glide on a track whose permeability and elastic properties are similar to goose down.
