摘要
介绍了周期幅值法测量地磁场的实验方法,指出了原实验设备存在的问题,同时提出了实验设备的改造方案,并详细介绍了如何软选取件模块.该工作降低了实验教学的维护成本,节约了因等待维护耗费的大量时间,保证了实验教学的顺利进行.
The experimental method of measuring geomagnetic field by periodic amplitude method was introduced.The problems existing in the original experimental equipment were pointed out.At same time,the reform scheme of the experimental equipment was put forward.How to select the module of soft components was presented in detail.This work reduced the maintenance cost of experimental teaching,saved a lot of time for waiting for maintenance,and ensured the smooth progress of experimental teaching.
