title: JESS, a joint expert speciation system-III. Surrogate functions.
abstract: A new, general method of coupling calculations of equilibria with those of other chemical effects and processes is described. The method, based on the use of simple empirical functions, is demonstrated by applying it to changes of ionic strength and temperature in speciation modelling.
