摘　　要：水质COD、DO测试易受各种主、客观因素影响,其测试结果是一具有可信度的未确知数。为确保测试结果能正确反映所测COD、DO实际情况,进行测试结果的可信度分析显得尤为重要;为此,本文将未确知数理论运算应用于水质COD、DO测试结果的可信度分析,以确保测试结果的可靠性。经理论分析和实际测试表明,该法较好地评判水中COD、DO测试结果以及相应于结果的可信度,可推广应用于水质分析。It is known that the measuring of COD and DO of water quality is influenced by various unpredictable factors, thus the measured results obtained were of unascertained numbers with certain confidence level. In this paper, the confidence levels of COD and DO data were analyzed by the unascertained mathematics to assure the reliability of the measured results. It was found that the method is applicable in assessing the COD and DO data, as compared with the actual results obtained.
