Head Ulitko Andrii F., Registration Date 25-02-2005 Organization Taras Shevchenko Kiev university popup.description2 An extended Euler's dynamic equations have been established. These equations are joined with the dynamic Lame equations of motion prevoiusly found. Such a coupling exists due to the common electric field variables, angular velocity components, and the relative elastic displace-ments. The first integral of Euler's equations has been derived and formulae of the small deviations of angular ve-locity due to the waves and vibrations in the moving solid have been found. Some models of evaluation of electric potential transfer ratio have been suggested for the dielectric medium; time-exponential law of popential decreacing and its dependence of the conductivity and dielectric features around the drilling string in the dielectrically inhomogeneous surrounding medium are found.5635 Product Description popup.authors popup.nrat_date 2020-04-02 Close
