介绍了溶液在线分析系统的测定原理和系统结构。对数学模型的修正作了详细讨论。程序运算得到的溶液浓度值与化验室分析值的相对误差不超过± 2 .5 % ,测量结果的精度能满足生产工艺的要求 ,对生产具有现实的指导意义
The principle of determination and system structure of solution online analysis system are introduced. Amendments to mathematical models are discussed in detail. The relative error between the solution concentration calculated by the program and the analytical value of the laboratory does not exceed ± 2.5%. The accuracy of the measurement result can meet the requirements of the production process and has a realistic guiding significance for the production
