摘要基于出磨水泥的部分检验数据，对采用JC/T 738附录A中的方法求出的一元一次回归方程和利用Excel中的数据分析功能求出的多元一次回归方程，进行水泥28d抗压强度预测精确度对比。对比结果显示，利用Excel数据分析功能求出的多元一次回归方程对水泥28d抗压强度的预测值更加精准。

Abstract: Based on partial test data of ground cement, the prediction accuracy of 28d compressive strength of cement is compared between the single-variable one-time regression equation obtained by the method in appendix a of JC/T 738 and the multiple-variable one-time regression equation obtained by the data analysis function of Excel. The comparison results show that the prediction value of 28d compressive strength of cement is more accurate by using the multiple regression equation derived from Excel data.

Key words: compressive strength regression equation blame hypothesis fitting coefficient
