磁粉离合器和制动器作为一种多用途的自动控制元件,正日益为人们所重视。它们已经广泛用于自动控制的各个领域。一些主要资本主义国家对磁粉离合器的研制十分重视,并已成系列生产。随着机种的多样化和科学技术的进步,必将不断扩大它们的应用范围。为了满足国内有关单位研制磁粉离合器的需要,“洋为中用”,我们选译了三篇资料,以供参考。 Magnetic clutch and brake as a multi-purpose automatic control element, is increasingly valued. They have been widely used in various fields of automatic control. Some major capitalist countries attach great importance to the development of magnetic clutch and have become a series of production. With the diversification of models and the advancement of science and technology, their range of applications will surely continue to expand. In order to meet the needs of the relevant domestic units for the development of magnetic clutch, “foreign for the use of”, we selected the translation of the three materials for reference.
