| 摘 要： | 本文基于导出的河流水质系统随机状态空间模型，提出了以能够即时测定的ＤＯ浓度实时估计不易测定的ＢＯＤ浓度的塔穆勒滤波方法。通过仿真实例，证明了该滤波方法能在较大范围内适用于河流水质系统的状态估计，用ＤＯ估计ＢＯＤ是可行的。

| Abstract: | Based On the derived random state model of river water quality syst-em,Tamura filter was presented to estimate BOD concentration only using DO concentration,which can be measured immediately.By the computer simulatiOn stu-dy and the test of a pract ical example,it was verified that Tamura filter can be used for the real-time estimation of water qualitv state in a large range,and it is feasible tO use DO concentration tO estimate BOD concentration. |
