摘要
介绍了COD和BOD的原理,及二者关系的确定,阐述了回归方程精密度和准确度的检验过程。对于水质比较稳定的污水进行检测,利用相关关系快速计算BOD5值具有的实际意义和经济价值。
In this paper, the author introduced the principle of COD and BOD as well as the identifying relationship. Also the author elaborated the testing process of precision of regression equation and accuracy degree. The water quality testing of relatively stable polluted water as well as quick calculation of BOD5 values by using correlation have practical significance and economic value.
