%X 推导了中国煤的哈氏可磨性指数计算公式,并通过试验研究证实:在整个量值范围内,线性回归计算公式溯源性最好;单点拟合计算公式在"拟合点"附近具有较好的量值溯源性,但在整个量值范围内不及单点拟合加权计算公式。 The paper has derived the China's formulae for calculating Hardgrove grindability index of coal, and experiment study shows that linear regression formula is best in the whole value scale, and that near "regression point", "single point" regression formulae offer better value accuracy, but not as good as "single point" regression weighted formula in the whole vlaue scale
