Показано, что при исследовании таких релаксационных характеристик как тангенс угла механических потерь, диссипация механической энергии в результате внутреннего трения, измеренных при периодическом воздействии одноосного сжимающего напряжения на образце полимера (ПВД) в высокоэластическом состоянии, происходит процесс развития релаксации. В связи с этим необходимо учитывать температурно-временные условиях эксперимента или вводить соответствующие поправки в полученные результаты.

It is shown, that at research such relaxation characteristics as the tangent of mechanical losses, dissipation of mechanical energy as a result of the internal friction, measured at periodic action of monoaxial compressive stress on the sample of polymer (LDPE) in the high elasticity state, occurs development relaxation processes in the sample. In this connection it is necessary to take into account the temperature-time conditions of the experiment or introduce appropriate amendments to the results obtained.
