| 摘 要： | 在研究元素分析和工业分析指标相关性的基础上,利用MATLAB对全国126个矿井的无烟煤煤质分析数据进行了多元线性逐步回归分析,推导出了元素分析和工业分析关联方程组和关联矩阵,并对其进行了验证,建立了由工业分析指标对元素分析指标的通用计算模型。该模型将关联矩阵推广到全国范围内的无烟煤,具有一定的实用价值。

| Abstract: | On basis of analysis on correlation of index of element analysis with index of industrial analysis, multi-linear gradual regression analysis has been carried out on quality of anthracite coal from 126 collieries of China by use of MATLAB. The correlated equation and matrix of element and industrial analysis has been derived and proved thus, the universal calculation model has been set up for industrial analysis index and element analysis index. By use of this model, the correlation matrix will be popularized and applied in anthracite coal produced in China. Therefore, the model has a certain practicable applicability. |
