摘　　要：差热分析仪的基线误差过大是造成仪器不能正常工作的主要原因 ,本文采用微机通过 A/ D采样 ,再经数据处理 ,由 D/ A送出修正的方法较好地解决了以上问题。同时 ,用这种方法可使原仪器升级成为全自动分析仪。Differential thermal analysis is an important determination technology in the physical and chemical analysis.Generally,the principal reason of unstable work in differential thermal analysis is caused by irregular line.This problem can be solved by amendment and compensation with computer.Instrument principle ,reason of the error and method of the amendment and compensation are reported.Meanwhile,the instrument can be reformed into automatic analyser by this technology.
