摘要
无论采取什么测试技术来测试水质化学需氧量(COD),测试过程均受各种主、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水质实际情况,进行测试结果的可信度分析显得尤为重要;为此,将未确知数理论运算应用于水质COD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,该方法较好地评判水中COD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.表2,参10.
For effect of subjective and objective factors, whatever measurable technology, the measurable result of COD its water is unascertained mathematics. So it is important link to analyze reliability of the measurable result of COD. Operations of unascel-tained mathematics in analyzing COD of water was put forward in this paper, and it get COD of water which have reliability, and wide - ranging apply in analysis of water. 2tabs. , 10refs.
