摩擦系数主要受纳米管径的影响，还受表面粗糙度和弹性模量的共同影响。
Frictional coefficients were mainly related with nanotube diameters of specimens, next with surface roughness and elastic modulus of specimens.
若流线型物体表面的摩擦阻力系数仅为相对粗糙度的函数，则形状阻力系数与雷诺数无关。
Since if the frictional resistance coefficient is a function of relative roughness, then the form resistance coefficient is independent of the Reynolds number.
