摘要
在自动化测试系统中，提高仪器测试精度不仅依赖于硬件电路的性能，而且取决于对测试数据的事后处理上．基于这一观点，本文提出了利用软件提高测试精度的方法，导出了最小二乘法的具体算法及实际应用结果．在文章的结尾，还论述了进一步提高测试精度的措施．
In auto measurement system,the instruments' precision depends not only on the performance of hardware circuits,but also on the testing data treatments afterwards.This paper point out the method to improve testing accuracy based on software,several actual algorithm and applying result are deduced.In the end of this paper,additional measures are discussed.
