A method for calculating matrix elements of dispersion law in complex crystals is
developed. A general scheme of solving vibration problem under natural
coordinates is given. Methods for constructing operational operator and its
generalization for the cas
A method for calculating vibration frequencies of atoms of individual chemical
bonds in complicated crystals is developed. A procedure for finding vibration
form by means of molecular models is given.
The riemanian metric was used in chemical bond theory. By way of concrete examples
the effect of methods elaborated by the author was demonstrated from the
formulation the problem to the calculation of the problem to calculation of the
equilibrium curve.

In the “Journal of Thermoelectricity”, N1, 1993 a theory and technique were represented for the description of well-known thermoelement types and creation of new ones. As the author of this paper, I promised to develop this subject further with the appearance of a new information. I have managed by now to study rather thoroughly the state of affairs with the main thermoelement types serving the basis for thermoelectricity that are being currently used or can find practical applications.
