| 摘 要： | 鞍本地区“鞍山式”铁矿石品位与体重呈线性关系,相关系数为0.977047038;经筛选,选取了1557组品位--体重数据,建立起鞍本地区“鞍山式”铁矿石品位--体重的一元回归方程y=0.030774255x+2.376616029;经过在新矿区的应用试验,证明基于大样本、宽品位范围建立的一元回归方程更具代表性、客观性.

| Abstract: | Grade vs volumetric weight of Anshan type iron ore in Anshan-Benxi area is linear with correlative coeficient of 0.977 047 038.1 557 sets of grade vs volumetric weight sample were picked up to establish unitary regression equation y=0.030 774 255x+2.376 616 029 and tests in the new mining areas proved that the unitary regression equation based on big specimen and wide range of the ore grade is more objective and representative. |
