An investigation of the infrared spectra of melt water at room temperature

It was shown experimentally that the infrared spectra of melted and never-frozen distilled water differed at frequencies of 1640 and 2130 cm^?1. This is explained by the long relaxation of water molecules structures to an equilibrium state in melt water. It was suggested that near the frequency 2130 cm^?1 there was a bigger influence of dissolved gas relaxation on the value of the transmitted intensity of infrared radiation than near the 1640 cm^?1 line.     

Functional integration method in the investigation of the dynamics of model Hamiltonians

The dynamics of the BCS and Dicke models is studied by the functional integration method. Expressions are obtained for the generating functionals of the temperature-time Green's functions of the models in question.Translated from Zapiski Nauchnykh Seminarov Leningradskogo Otdeleniya Matematicheskogo Instituta im.

On the theory of flow of an incompressible viscous fluid in a channel of arbitrary section

An exact solution is constructed to the problem of the stationary flow of an incompressible viscous fluid in a straight tube whose section is formed by two connected rectangles.Translated from Izvestiya Akademii Nauk SSSR, Mekhanika Zhidkosti i Gaza, No. 2, pp. 124–128, March–April, 1980.
