摘　　要：本文介绍了一种基于声学非接触式高等级砝码体积测量方法对不同形状、不同材质及带腔体的固体材料的质量砝码体积参数的测量结果及其不确定度评定,并通过大量试验验证了其测量结果的不确定度小于6×10^(-4)(k=2)。abstract： In this paper, an acoustic volumeter is proposed for the t of the volume of weights. The procedure for uncertainty evaluation of volume measurement results of different material and different shape weights using the acoustic volumeter method is proposed. Through a large number of experiments, the reliability of the measurement was evaluated with a relative uncertainty below the order of 6×10（-4）（k=2）.
