摘　　要：实验室中的砂浆搅拌机在使用过程中由于受仪器设备和人员操作等影响,搅拌叶转速不可避免地会发生改变,从而引起均匀性的下降。从实际操作出发,分析搅拌叶转速的测量不确定度的来源,给出了测量结果分量不确定度的评定方法。In the laboratory using a mortar mixer process due to equipment and personnel affected operation, a stirring blade rotation speed inevitably changes, thus causing decrease in uniformity. From the practical analysis of source mixing blade speed measurement uncertainty, given the results of evaluation methods for measuring components of uncertainty.
