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.

The technology of laser welding by a transmission method allows welding overlapping polymeric films and sheets of various thickness. Welding of polyvinyl chloride films using a diode-pumped solid-state laser (DPSS) of 10 W power, which generates green radiation with wavelength of 532 nm, was performed in the developed experimental equipment. Application of this method made it possible to weld transparent multilayer medical films Wipak. Experiments have shown that with the help of such a laser it is possible to form a high-quality joint of Wipak medical film with paper. 9 Ref, 5 Fig.
