多溶质渗透维里方程是唯一的多溶质热力学溶液理论，已来自第一原理，并可以作出预测的多溶质溶液的行为，在没有多溶质溶液的数据。其他溶液理论要么（i）包括不考虑不同类型溶质分子之间相互作用的简化假设，要么（ii）需要拟合多溶质数据以获得经验参数。从单溶质数据得到的渗透维里系数可以用来预测多溶质溶液的渗透压。渗透维里系数的范围内感兴趣的溶质在低温生物学中提供，用于与浓度单位的质量摩尔浓度和摩尔分数，沿着的背景和理论的解释，必要的实施多溶质渗透维里方程。(C)2009爱思唯尔公司All rights reserved.
The multisolute osmotic virial equation is the only multisolute thermodynamic solution theory that has been derived from first principles and can make predictions of multisolute solution behaviour in the absence of multisolute solution data. Other solution theories either (i) include simplifying assumptions that do not take into account the interactions between different types of solute molecules or (ii) require fitting to multisolute data to obtain empirical parameters. The osmotic virial coefficients, which are obtained from single-solute data, can be used to make predictions of multisolute solution osmolality. The osmotic virial coefficients for a range of solutes of interest in cryobiology are provided in this paper, for use with concentration units of both molality and mole fraction, along with an explanation of the background and theory necessary to implement the multisolute osmotic virial equation.
