通过对沉降法中的浮力秤法理论的重新讨论，发现了新的平均粒径的解析和定义。本文提出了一种基于液体沉降速度的平均粒径。本文用浮力秤法定义了新的平均粒径，即所有颗粒的速度平均粒径[方程]，如下所示。【方程式】ΔGi为粒子xi的浮力差质量。均质颗粒和球形玻璃珠的三元混合物被用作样品。虽然浮力称量棒法也很耗时，但可以在开始测量后的短时间内得出最大粒度和平均粒度。
New analysis and a definition of the new mean particle size have been discovered by rediscussing theory of the buoyancy weighing-bar method, which is a type of sedimentation methods. This paper proposes a new mean particle size based on the settling velocity in liquid. The velocity mean size of all particles [equation], which is the new mean particle size defined in this paper by the buoyancy weighing-bar method, is given as follow.[equation]ΔGi is the buoyancy difference mass of particles xi. Homogenous particles and a ternary mixture of spherical glass beads are used as the samples. Although the buoyancy weighing-bar method is also time-consuming, the maximum particle size and the mean particle size can be derived within a short time after initiating measurement.
