根据马尔文MS2000说明:
Density=1500 kg/m3,此密度是颗粒密度还是骨架密度?
Density – the density in g/cm3. This is used to calculate the Specific Surface
Area (SSA). Users who want to include the SSA as a derived parameter must
complete this field.
应该指样品密度,通常是用户输入或系统默认,粒度仪应该无法测量密度的,利用密度可以用于计算样品的比表面积。
Span=1.438E+00 Span是什么意思?
The Span is the measurement of the width of the distribution. The narrower the distribution, the smaller the span becomes. The span is calculated as: (d90-d10)/d50
反映样品粒度的分布宽度
Uniformity=4.354E-01 Uniformity是什么意思?
a measure of the absolute deviation from the median.
表征与d50的标准偏差,反映了分布的对称性或接近正太分布程度。

从楼主提供的信息来看,这首先应该是表面积与被分析物相对应的关系kg/m2,再换算成立方体kg/m3
