对生产装置单一原料主要产品收率的线性回归分析

Linear Regression Analysis of Main Product Yield From Single Raw Material in the Production Plant

以无截距线性回归模型及 SPSS 软件对一生产装置单一原料的主要产品收率进行线性回归分析,通过对该装置 23 组投入产出数据的研究,确定了回归效果显著、稳定性良好的无截距项线性模型,得到了有代表性的单一原料的产品A、B的收率.该分析方法的正确建立,对优化装置原料结构有意义.

The linear regression analysis of the main product yield from a single feedstock in the production plant was carried out with the non-intercept linear model and SPSS software.Through the study of 23 sets of input-output data of the device,a linear model without intercept term was established.The model had obvious regression effect and good stability,and the yields of the products A and B of single raw material were obtained.The establishment of the analytical method is of great significance to optimize the raw material structure of the plant.
