摘要：

We derive a formula for the correlation of the three practical transport parameters L-p, sigma, and omega appearing in Kedem-Katchalsky equations. It has a form omega = KLp/<(vs)over bar>(1 - sigma), where K = 0.0306 is a universal constant independent of the choice of a membrane and a solute. It can be used to calculate the value of any of these parameters, provided the other two and the molar volume <(vs)over bar> of the solute are known. The formula could be very useful, in particular when measurements of the parameters are difficult or even impossible.
