摘　　要：论文以炼油厂连续重整工艺为例,对精馏塔馏出口芳烃含量软仪表的建模过程进行分析,通过对工艺模型的深入剖析,并利用数学中迭代算法进行数据的非线性回归,从而得出软仪表模型,提出了软仪表建模的新思路,对今后提高软测量精度具有重要意义。Taking the continuous reforming process of the refinery as an example, the paper analyzes the modeling process of the soft meter of the aromatics content in the distillation column. Through the in-depth analysis of the process model, and the use of mathematical iteration algorithm for data non-linear regression, we get the model of soft instrument and put forward a new idea of soft instrument modeling, which is of great significance to improve the accuracy of soft measurement in the future.

关 键 词：软仪表 非线性回归 数据线性化
