摘　　要：针对鄂尔多斯地区煤样,对其做灰成分分析,并测得其灰熔融温度,根据其灰成分建立灰熔融点预测模型,采用MATLAB软件运用最小二乘法对煤灰成分及灰熔融温度数据进行线性回归分析,依据预测模型得出的预测值与实测值有较好的一致性。According to the coal samples in Ordos region, the ash content was analyzed, the ash melting temperature was measured, the gray meltin point prediction model was established based on the ash content, and the least square method was used to carry out linear regression analysis on ash composition and ash melting temperature using MATLAB software regression analysis, and the predictive value and the measured value. Have good consistency.
