The results show that the couple stress fluid flow behavior depends on not only the coefficient of viscosity, but also the material constant responsible for the couple stress parameter.
It must choose the sizing agent with high concentration, low viscosity and high fluidity, so can guarantee the constant sizing rate and suitable coverage and soakage.
必须选择高浓度、低粘度和高流动性的浆料组合，以保证恒定的上浆率和比例恰当的被覆与渗透。

The reaction rate constant and activation energy of soybean oil thermal polymerization reaction were determined by analysis of the change of viscosity.
