煤的发热量与灰分的线性关系分析

Linear Correlation between Coal’s Calorific Value and Ash Content

通过对50组煤的发热量数据与灰分数据进行相关性分析,建立了两者之间的一元线性回归模型,并对该回归模型进行了检验,进而可借助该回归方程通过灰分数据快速地预测发热量值。

Through the correlation analysis on the data of calorific value and ash content of 50 groups of coal samples, this paper establishes and verifies the single-variable linear regression model between calorific value and ash content, which can be used for the quick prediction through the data of ash content.
