一、前言测试结果的重现性是评定试验仪器性能的重要标志。本试验试图通过ABRASIVM3000标准试样、国产钼粉末和TiH_2粉末的粒度分布、平均粒度及粉末颗粒表面积的标准误差的计算,以及自动记录过程跟踪曲线的分析,来表征试验结果的重现性以及评定该测定方法的优劣。 I. Introduction The reproducibility of test results is an important indicator of the performance of test equipment. This test attempts to characterize the reproducibility of the test results and the evaluation by ABRASIVM3000 standard sample, the particle size distribution of domestic molybdenum powder and TiH2 powder, the calculation of the standard deviation of the average particle size and powder particle surface area, and the analysis of the tracking curve of the automatic recording process The merits of this method.
