翻译一下下面几句专业术语，最贴切的每句50个金币 1、分析粉末或块状固体的孔尺寸分布、总孔体积、总孔面积、样品堆/真密度、流体传输性等物理性质 2、化学吸附和物理吸附测试，可测试金属分散度、活性金属面积、晶体尺寸、利用脉冲化学吸附定量酸性强度及碱性强度。物理吸附测试包括BET和Langmuir比表面、总孔体积。 3、堆密度分析仪用于分析堆密度和粉粒包装研究，包括预测流动性的Harsner比和carr指数。 |

1.analysis of physical properties of powders and bulk solids contain pore size distribution, total pore volume, total pore area, the sample stack / true density, and the transmission property of fluid. 2.The test of chemical adsorption and physical adsorption can test the metal dispersion, active metal area, crystal size and quantification of acidic and basic strength based on the use of pulsed chemisorption. Tests of physical adsorption contain the specific surface area of BET and Langmuir, and total pore volume. 3.Bulk density analyzer applies to analysis of bulk density and study on powder packing,including Harsner ratio for predication of Flowability and carr index |
