coefficient of viscosityn.(名词)【复数】 coefficients of viscosity
The degree to which a fluid resists flow under an applied force, measured by the tangential friction force per unit area divided by the velocity gradient under conditions of streamline flow.粘滞系数:在施加的力作用下流体阻止流动的程度,由单位面积上的切向摩擦力除以流线流动情况下的速度梯度来度量
