Data confidence 70 medium
How this score is calculated

It is built from checkable properties of the record itself: whether the article has a DOI, how many independent sources confirmed its data, whether the required fields are filled in, and how recent the latest confirmation is. Disagreement between sources and a missing identifier lower it. A value of 80 or above means the record was published without further checking; 60 to 79 means it is published at reduced confidence, with a manual check advisable. A record verified by an editor by hand is never pushed below 90 by a recalculation. This scores our data about the article, not the article itself.

Abstract

В данной статье исследуется проблема акустики в пористых средах в трех отдельных областях. В каждой области предполагается, что материалы обладают разными физическими свойствами. Геометрия пор, вязкость жидкости располагаются в середине двух упругих областей. В этой задаче сначала рассматривается решение дифференциальных уравнений. Математическая модель этих физических явлений описывается начально-краевыми задачами для сложных систем дифференциальных уравнений в частных производных. In the article, we investigate the problem of acoustics in porous media in three separate areas. In each area, it is assumed that the materials have different physical properties. Geometry of pore, fluid viscosity is located in the middle of two elastic areas. In this problem, we first consider the solution of differential equations. The mathematical model of these physical phenomena is described by initial-boundary value problems for complex systems of partial differential equations.
