In this case, for a complicated formula, a special function is created, although the activation of the calculation functions remains unchanged. Thus, this library is related to the libraries with the universal interface. The use of the mpUniLib library in program products includes three stages. At the first stage, it is the initialization of the DB and of all the necessary properties set by the user. At the second stage, the calcu- lation of the properties in the calculation code is made.
At the third stage, it is the liquidation of the indi- cators and exemption of the dynamic memory that is supposed to store the data.
In the mpUniLib library, the capabilities of automatically processing the meanings of arguments found outside the interval of measurements are implemented in the mode of data extrapolation. The library also has the possibility of automatically smoothing the thermophysical properties in the field of the phase tran- sition. The library has the corresponding tools for implementation by the user of his algorithms for smoothing and extrapolating the data.

The wpLibrary contains calculation functions for determining the properties of water and steam in the variables pressure—temperature, pressure—enthalpy, ans pressure—entropy, as well as on the line of satu- ration and in the two-phase area. The calculation formulas for water and steam are rather difficult because of the large number of coefficients. This makes the use of the formula analyzer inefficient.
Thus, for the basic and auxiliary formulas in the library, special calculation functions have been created. The library has two groups of functions: basic functions and table functions. The basic functions implement the equations of the International Association on the properties of water and steam, so they are highly accurate, but have a low calculation rate.
They do not require initial- ization and can be used immediately after the library files are connected to the project. The use of the table functions presupposes also the presence of three stages, i. At the stage of initialization, the two-dimensional tables are created by use of the previously mentioned basic cal- culation functions that are used later for the calculation of properties.
A good feature of this part of the library is also the calculation speed. Its shortcoming is the loss of accuracy due to bilinear interpolation. For comparison, the speed of the calculation of properties in the pressure—temperature variables in the use of the basic functions is — ns, whereas in the table functions, it is 14—16 ns. The present graphic interface created for DB management offers the user many opportunities in edit- ing and displaying graphic information, creating tables, as well as exporting and importing data.
