比例粘度viscosity/density ratio,kinematic viscosity 流体的绝对粘度与流体的密度之比值为比密粘度。 ν=η/р v——比密粘度 η——绝对粘度 р——流体的粘度( 厘米·克·秒制单位为沲（stokes）；米·公斤·秒制单位米2/秒（=104沲）
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。
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.
同理，对于双螺杆泵，粘度大的流体比粘度小的液体的泄漏要小，泄漏量与介质粘度有一定的比例关系。
Similarly, for the twin-screw pump, the fluid viscosity smaller than the viscosity of the liquid leakage is smaller, leakage volume and viscosity of a certain percentage of media relations.
