MMD是指质量(或体积)中位径,与CMD,SMD的换算关系如下: For a log-normal distribution, there are closed-form relationships between median diameters of different weightings. The count median diameter (CMD) is related to the surface median diameter (SMD) by ( ) g SMD = CMD∗ exp 2ln2 σ (7.26) The CMD is related to the mass (or volume) median diameter (MMD) by ( ) g MMD = CMD∗ exp 3ln2 σ (7.27) The relationship between MMD and SMD is ( ) g MMD = SMD∗ exp ln2 σ
