description The invention provides a method for representing the mixing uniformity of mixed powder and a method for evaluating the mixing uniformity of various mixed powders.The method for representing the mixing uniformity of the mixed powder comprises the steps that the mixed powder is provided, and a plurality of powder samples are taken from the mixed powder; each powder sample is compacted, and the volume of each compacted powder sample is measured; the tap density rho of each powder sample in the multiple powder samples is counted, rho = m/v, m is the mass of each powder sample, and v is the volume of each powder sample after being compacted; the dispersion coefficient Cv of the multiple powder samples is used for representing the mixing uniformity of the mixed powder, Cv = sigma/mu, sigma is the standard deviation of the tap density rho of the multiple powder samples, and mu is the average value of the tap density rho of the multiple powder samples. By adopting the method for representing the mixing uniformity of
