摘要：
采用普析通用公司生产的TW-6000自动水质监测仪测定COD,与标准法 (GB11914-1989)进行对照实验,再应用数理统计方法对结果加以分析,证明仪器法和标准法的数据无显著性差异 (显著性水平为0.05,样本数为15),且两者具有相似的精密度和准确度

Abstract:
The water quality automonitor, TW- 6000, produced by Beijing Purkinje General Inst rument Co.,Ltd. is adopted to examine COD, to do check test with standard method ( GB11914 1989) and to analyze the results by mathemat ical stat ist ics. It is proved that there is no not iceable dif ference between the inst rumental method and the standard method(is 0.05 and the number of samples is 15) and the two methods have similar precision and accuracy.
