气煤葛金焦型与自由膨胀序数的回归分析

Regression Analysis between Gray-King Assay Coke Type and Free Swelling Index on Gas Coal

本文着重讨论了气煤葛金焦型与自由膨胀序数的相关关系。以若干气煤和肥气煤的化验数据为基础,运用数理统计原理,确定了气煤的焦型与自由膨胀序数之间存在的线性相关关系,并建立了对应的回归方程:

This paper mainly deals with the correlativity between Gray-king Assay coke type(GAC) and free swelling index(FSI) on the gas coal. Based on a lot of the experimental data of the gas coal, with the mathematic statistics principle, there exists linear correlation for determination between GAC and FSI on the gas coal, the author therely derived an optimum regression equation: Y = 4 + X.
