АВТОМАТИЧЕСКОЕ ЗАДАНИЕ АМПЛИТУДНЫХ ЗНАЧЕНИЙ МАГНИТНОЙ ИНДУКЦИИ ПРИ ИЗМЕРЕНИИ ХАРАКТЕРИСТИК ЭЛЕКТРОТЕХНИЧЕСКИХ СТАЛЕЙ

The problems relating to an automation of measurement of magnetic characteristics of electrical-sheet steel have been considered in the paper. The paper investigates efficiency of an application of some well-known iterative methods for setting the required amplitude value of a magnetic induction of the material to be tested. It is shown that the most efficient method providing a fast and stable convergence of an iterative process while testing either textured or isotropic electrical-sheet steel is a parabola method.Рассматриваются вопросы, касающиеся автоматизации измерения магнитных характеристик электротехнических сталей. Исследуется эффективность применения известных итерационных методов для задания требуемого амплитудного значения магнитной индукции испытуемого материала. Показано, что наиболее эффективным методом из исследовавшихся, обеспечивающим быстрое и устойчивое схождение итерационного процесса при испытании как текстурованных, так и изотропных электротехнических сталей, является метод парабол

Search for Collective Phenomena in High Multiplicity Events at Nuclotron and U-70

More than ten-year experimental search for collective phenomena in high multiplicity events has been carried out at the Laboratory of high energy physics at JINR. We present main results, which have been received at the U-70 accelerator (IHEP, Protvino) in the proton collisions and at Nuclotron ( JINR, Dubna) in the nuclear interactions. Fo
