В настоящее время подобные эффекты считаются помехой, в то время как некоторые исследователи указывают на то, что они содержат полезную информацию об исследуемой среде.</p><p>В статье приведено моделирование импульсных характеристик вязкой намагниченности. Используя модель логнормального распределения частиц, были смоделированы различные импульсные характеристики намагниченности. Представлены результаты попыток восстановить параметры распределения  и  модельных импульсных характеристик. Приведена оценка эффективности инверсии синтетических импульсных характеристик.</p></abstract><trans-abstract xml:lang="en"><p>TEM survey under objects that containing superparamagnetic particles, the effects of magnetic viscosity can have a significant impact on the received signal.
