摘要
介绍了自行研制的一种新型微型脉冲充磁仪,它由高频开关电源电路、高压充电及大电流快速开关电路等部分组成。阐述了仪器的工作原理和结构设计。通过对“1∶25万聂拉木县幅磁性地层研究专题”样品的充磁测试表明,利用新研制的微型脉冲充磁仪进行等温剩磁测定,可以客观、准确地判断岩石样品中的磁性矿物成分。
A subminiature pulsed magnetizing device used for magnetization of geological samples is developed. It is composed of high frequency switching circuit, high voltage charging circuit, huge current quick make switch circuit ect.. The working principle and structural design of the device are also presented. The device has been successfully applied to magnetization of geological samples and isothermal magnetic remanence measurements. It provides an effective tool for identifying magnetic minerals in rocks.
