摘　　要：以HMC—1022磁敏元件为基础,开发了二维弱磁检测仪器,利用自行设计的简易标定系统,测定了主要技术指标。选用拉伸后的A3钢试件进行检测,将结果和俄罗斯的TSC—1M—4型磁记忆检测仪检测结果进行了对比,二者的曲线变化规律基本相同。用Matlab软件画出检测结果立体图,在图形中可以准确地找到已知缺陷的位置。A two-dimensional low intensity field detecting instrument is developed based on the magnetism sensor HMC-1022 ,and its main technology index is.tested by using a simple self-made calibration system. In the tension experiment of A3 steel,the sample is tested with both the developed instrument and Russian TSC-1M-4 magnetic memory testing instrument. Compared the testing results,it is found that the change rule of two eurves is alike. The testing result is drawn solfware by using Matlab to a three-dimensional graph, and the self-mede defect is exactly found in the graph.
