In the exploration of TEM sounding, decay curves and late time apparent resistivity curves as the original data are core contents in the field data acceptance. However, the pre-processing software compatible with instrument often cannot generate batches of maps. Technicians need to screenshot from the software, which is not only tedious, but also lack of the corresponding concerned information. By reading USF data through the MATLAB program, the batch production of the original curves and the comparative analysis of data can both be realized.% 瞬变电磁测深勘探中，衰减曲线和晚期视电阻率曲线图作为原始资料是野外资料验收的核心内容之一，而仪器配套的预处理软件往往不能批量地生成相应的图件，技术人员需从软件中截图来实现，这一工作不但繁琐，而且缺乏相应的信息。通过编制MATLAB程序读取相应的USF数据，实现原始曲线的批量绘制，并可进行试验数据的对比分析。
