摘要
应用SPSS统计软件对神华石炭4号煤和外购2号煤中氢含量与水分、灰分、挥发分间的相关性进行了多元线性回归分析。经过检验和验证,表明回归方程具有较好的拟合优度及较高的显著性和准确性,可以用于煤中氢含量的计算。
The multiple linear regression analysis on the relationships between the hydrogen content and moisture content, ash yield, volatile matter of the Shenhua 4^# coal （carbonization period） and 2^# coal （purchased outside） by SFSS statistical software was introduced in this paper. The results from tests and verifications showed that there was a better regression relationship with relatively higher significance and accuracy, which could be used for the calculation of coal hydrogen content.
