Classes and objects of chemical thermodynamics in object-oriented programming. 1. A class of analytical functions of temperature and pressure

The development of principles that might ease writing software for thermodynamic calculations with any participating solutions has been considered as the objective of this paper. To this end, the object-oriented programming is suggested to apply, which, in fact, allows the creation of a new specialised algorithmic language, rather universal and flexible, for programming of sophisticated thermodynamic applications. This also makes it possible to represent any thermodynamic property by arbitrary user-supplied analytical functions and furnishes a new way for the storage of thermodynamic properties in a data bank.
