一、前言电子计算机的存贮元件,自动控制中无触点继电器及原子能、电子学中应用的脉冲变压器等方面,都需要矩形磁滞回线的磁性材料。由于我省自1958年大跃进以来,在原子能、自动控制、计算技术等各方面的发展,和全国一样日新月异,因此对具有矩形磁滞回线的磁性材料的需要也提到日程上来了。 First, the foreword The computer storage elements, automatic control of non-contact relays and atomic energy, pulse transformers used in electronics, etc., require a rectangular magnetic hysteresis loop magnetic material. Since the province’s great leap forward in 1958, its development in such fields as atomic energy, automatic control, computing technology and the like is as rapid as that in other parts of the country. Therefore, the demand for magnetic materials with rectangular hysteresis loops is also mentioned in the agenda.
