前言 我所的地面脉冲电磁仪的设计和研制,最初是由我所研制感应脉冲瞬态航空电磁仪的成员作为航电异常的地面检查和兼顾地面普查,而提出並进行研制工作的。1972年,该仪器的研制任务列入研制地面电法仪器的专题项目进行准备工作。1976年建立了独立的地面脉冲电磁仪研制专题组,並于1979年研制成DMD—Ⅰ型样机。经对原设计方案作了多处补充修改,並在广西、江西、湖南、湖北等地的不同类型金属矿床上进行了多次试验,于1982年中研制成两套DMD—Ⅱ型样机。自1982年底起,DMD—Ⅱ型仪器由有关的野外队在安徽试用。对
Introduction The design and development of the ground-based pulse electromagnet was first proposed and carried out by the members of the transient aeronautical and electromagnetic induction apparatus developed by our institute as the aerial inspection and the ground census. In 1972, the development of this instrument was included in the preparation of thematic project for the development of electrical equipment on the ground. In 1976 established an independent ground pulse electromagnetic device development group, and in 1979 developed a DMD-Ⅰ prototype. After several amendments to the original design scheme, several experiments were conducted on different types of metal deposits in Guangxi, Jiangxi, Hunan and Hubei. Two DMD-II prototype machines were developed in 1982. Since the end of 1982, the DMD-Ⅱ instrument has been tested in Anhui by relevant field teams. Correct
