摘要
从矿石品位的趋势性变化与随机性变化分析算术平均法与加权平均法在计算矿体平均品位中的误差大小，说明面积的大小有一定的权，权的大小必须给的恰当，否则加权平均法的误差将大于算术平均法的误差．
To analyze the great or small of error in average grade of ore body which is calculated by arithmetic mean method and weighted mean method from tendentious change and stochastic change of ore grade,it explains the great or small of area has certainly weight.The great or small of weight must be suitably defined,otherwise the error calculated by weighted mean method is big than the error calculated by arithmetic mean method.
