English abstract:
A mathematical model of the process of an acoustic wave propagation
in a relax environment has been investigated.
This mathematical model is widely used to describe and determine
the basic parameters of the wave process in the problems of ultrasound diagnostics.
The model is formulated in the form of the Cauchy problem
for hyperbolic equation of third order with the initial data,
which are analytical functions.
The class of entire functions, which is the class of existence and uniqueness of the Cauchy problem solution for the partial differential equation, which describes this wave, is established.
In the selected class of functions, the Cauchy problem solution is constructed using the differential-symbol method.
Examples of solving problems with specific initial data are given. The obtained results and the indicated methodology allow us
to determine the basic parameters of the process of acoustic wave propagation in the problems of ultrasound diagnostics.
