内容提示: 616 BULK DENSITY AND TAPPED DENSITY USP<616>BULK DENSITY AND TAPPED DENSITY 固体的松密度的测量很困难, 测量时, 轻微的震动就会导致松密度的不同。 因此, 可以知道粉末的松散性取决于粉末的来历。 而且压紧之后, 会有一个密度范围。 因此, 报告松密度时,必须说明结果是如何得到的。 微粒的相互...

<616> BULK DENSITY AND TAPPED DENSITY OF POWDERS 本章已与欧洲药典和/或日本药典的相应文本协调一致。 ♦未统一的部分用符号(♦)标记以表明这一事实。 粉末的堆积密度是未开发粉末样品的质量与其体积(包括颗粒间空隙体积的贡献)之比。因此,堆积密度取决于粉末颗粒的密度和粉末床中颗粒的空间布置。堆积密度以克...
