The median pore diameter depended on the size of porogen particle.
致孔剂的颗粒大小只影响多孔支架的孔径；

When the purity of potassium sulfate crystal is lower and the content of the potassium phosphogypsum is higher, the mediandiameter of crystal particle and the density of suspension are higher.
结果表明：当硫酸钾结晶产品纯度较低、钾石膏含量较高时，晶体平均粒径及悬浮密度均较大；

The K-Factor correlated linearly with dust concentration, this is due to the variation of dust particlemediandiameter.
