The momentum transfer at the main channel flood -plain interface can be described as an apparent shear stress which can be quantified as a function of the local turbulence at the interface.
将滩槽交界的动量传递描述为一表观应力，这个表观应力可以看作是交界面处的脉动函数并将其定量化。
The shear rate of modified CPVC was higher than CPVC and the melt apparent viscosity was lower at the same shear stress.
相同剪切应力下改性CPVC的表观剪切速率大于CPVC，熔体表观粘度小于CPVC。
It has been found that the apparent viscosity of PBR is sensitive to shear rate, shear stress, and to temperature at lower shear rate levels as well.
表观粘度对切变速率和切应力较敏感，并且，在低切变速率下对温度也较敏感。
