Then in order to dealing with the low redundancy of process industry sensor network , the procedure of building an accurate and efficient quasi - steady - state linear mass balance model is discussed in three steps : rough model establishment , model impovement and model validation . 2 然后针对流程工业生产流程网络的低冗余性,从初始模型的建立、模型的改进、模型的检验和校正这几个方面详细探讨了如何从生产流程的网络结构建立一个准确而有效的线性准稳态物料平衡模型。
