Ross方程是一种乘法程序，用于估计仅含溶质、仅含食品聚合物或溶质和聚合物混合物的含水未加工食品制剂的水活度（aw）。在Ross方程中使用单溶质溶液的精确aw值，对于120个多溶质溶液中的118个，预测精度为± 0.01 aw。±0.02 aw的例外情况发生在含有NaCl、KCl和CaCl2的浓缩溶液范围内。
The Ross equation is a multiplicative procedure for estimating the water activity (aw) of aqueous unprocessed food preparations that contain only solutes, only food polymers, or mixtures of solutes and polymers. Using accurate aw values of single solute solutions in the Ross equation resulted in prediction accuracies to ± 0.01 aw for 118 of 120 multiple-solute solutions. The exceptions at ±0.02 aw occurred within a range of concentrated solutions containing NaCl, KCl, and CaCl2.
