Ⅲ.鉄氧体鉄氧体自1946年作为工业产品出世以来,无論在使用范围、品种、性能及产量等方面,都有了很大的发展。从最低的頻率至最高的频率均有可供使用的鉄氧体器件,因此它已成为尖端科学技术中被广泛应用的器材。鉄氧体特别宜于在无线电频率下工作,由于它的应用,不但使无綫电仪表的綫路简化、体积縮小、性能提高、成本降低,而且由于某些独具的特性,开拓出一些新的科学領域,如微波铁氧体器件等等。鉄氧体的发展虽比金属磁性材料为晚,但它所涉
Since its birth as an industrial product in 1946, it has made great strides in terms of its scope of use, variety, performance and yield. It has become the most widely used device in cutting-edge science and technology due to the availability of oxygen-containing devices from the lowest frequency to the highest frequency. Because oxygen is particularly suitable for operation at radio frequencies, its use not only simplifies, reduces the size, increases performance and costs of radio instrumentation but also opens up new possibilities due to certain unique features Science, such as microwave ferrite devices and more. Although the development of oxygen is later than metal magnetic materials, it is involved
