| 摘 要： | 参数识别是水质模型应用的重要环节,结构可识别性是水质模型参数可识别性的基础.采用Taylor方法,对单河段CSTR模型的结构可识别性进行了研究.结果表明,以单河段首端水质作为输入,以末端水质作为输出,考虑COD_(Mn)、NH_3-N、NO_3-N和DO四个水质变量,CSTR模型在结构上是可以识别的.

| Abstract: | Structure identifiability is the basis of parameter identifiability of water quality models.The structure identifiability of CSTR model in a single river is studied by the Taylor method.It shows that if it takes the water quality variables of the first tank as the input, and the ones of the last tank as the output,the CSTR model is theoretically identifiable with COD_(Mn),NH_3-N,NO_3-N and DO under consideration. |
