【求助】USP32---bulk density and tapped density

欢迎纠错：
a comparison of the bulk and tapped densities can give a measure of the relative importance of these interactions in a given powder.
bulk density 堆密度或松密度
tapped density 敲(打)密度
堆和敲密度的比较可以衡量所给粉末之间相互作用的相对重要性
The tapped density is a limiting density attained after "tapping down"
敲密度是(往下)敲打之后得到的一个极限密度

a comparison of the bulk and tapped densities can give a measure of the relative importance of these interactions in a given powder.
bulk density 体积密度
tapped density 堆积密度
体积密度和堆积密度的比较可以衡量所给粉末内相互作用的相对重要性
The tapped density is a limiting density attained after "tapping down"
堆积密度是抽实之后能达到的极限密度

还是紧密度比较好听一点
