补充资料：粘滞性
粘滞性
Viscosity
又称"内摩擦"。流体即液体和气体内部阻碍其相对流动的特性。如果在流动的流体中平行于流动方向将流体分成流速不同的各层，则在任何相邻两层的接触面上就有平行而与流动方向相反的阻力存在。这种阻力称为粘滞力，或称内摩擦力。如果相距1cm的两层速度相差为1cm／s，则作用在1cm2面积上这种力的数值规定为流体的粘滞系数(或称为内摩擦系数），用以表示流体粘滞性的大小。沾滞系数的单位为泊。流体的粘滞系数随温度而变，当温度升高时，流体的粘滞系数减少。但在气体则增加。例如在20℃时，水的粘滞系数为0.01泊，甘油为8.3泊，空气为1.8×10-4泊；而在30℃时，水为0.008泊，甘油为6.3泊，空气为1.9×10-4泊。
