Найпростіші випадки збудження електромагнітних та акустичних хвиль у стовбурі, у призабійному просторі та оточуючих гірских породах нафтогазових свердловин. Head Ulitko Andrey Feofanovich, Registration Date 30-01-2003 Organization Taras Shevchenko Kiev university popup.description2 The complete system of vector equations of movement of piezo-active elastic bodies is deducted. Initial and vectorial boundary conditions what define uniqueness of a solution of the concret problems are formulated. It is shown, that presence of a three-dimensional motion does not change equations of state of piezoelectric transducers. The detailed analysis of dispersionless waves in an unlimited elastic half-space, with the unloaded boundary (Rayleigh waves) and in the piecewise-homogeneous space with a plan as the interface presented.5635 Product Description popup.authors popup.nrat_date 2020-04-02 Close
