Viscous friction is the fiction, or resistance to relative motion, between adjacent layers of liquid. The resistance of motion between these oil layers is called viscous friction.

粘性是液体流层问相对运动而产生的摩擦力或阻力。油层间所产生的运动阻力称为粘性摩擦力。

Analysis of bubble motion in the flow field was used to develop relations for the viscous stresses, turbulent stresses, and interfacial momentum exchange to close the model.

通过对气泡在流场中的运动和受力分析，给出了用以封闭模型的粘性应力、脉动应力、相间动量交换项的表达式。

Thus instead of Boltzmann equation this model equation may be approximately used to discuss the motion of gases in the transient region between molecular flow and viscous flow Iimits.

因此可以近似地用此模型方程序代替玻氏方程序讨论介于分子流和粘性流之间的过渡区的气体运动情况。

Freeze-frame, slow motion, colour filters and smoke give the film a distinctly undigital tone, viscous and personal, that focuses attention on the excellent performances of Kyra Sedgwick, Parker Posey and Fairuza Balk.
