Позорная война рф против Украины

Начата 20 февраля 2014 и полномасштабно продолжена 24 февраля 2022 года. С первых же минут рф ведет ее с нарушением законов и правил войны, захватывает атомные станции, уничтожает бомбардировками мирное население и объекты критической инфраструктуры. Правители и армия рф - военные преступники. Все, кто платит им налоги или оказывают какую-либо поддержку - пособники терроризма. Народ Украины вас никогда не простит и ничего не забудет.

Abstract
The problem of propagation of the gas-free combustion (SHS reaction) front in nanolayered foils in thermal contact with the mating surfaces is considered. It is shown that dependence of the rate of propagation of the combustion front on the intensity of heat removal is of a threshold nature: there are critical values of the intensity of heat removal at which the combustion conditions in the nanolayered foil-heat-conducting material system are suppressed.
 
 
Keywords: welding and brazing, multilayer foils, heat-conducting materials, mating surfaces, self-propagating high-temperature synthesis reaction, heat removal, threshold thickness, analytical estimation
