空气尘埃的粒子数和质量之间怎么转换,单位从个/m3转换成ug/m3
好复杂的：
Mass =(p / 6) × D^3 × s × Kabs ×0.000001
D = Average Particle Diameter of bin
s= Density of Particle (mg/mL)
Kabs = Correction for different absorptionof real particles compared to latex spheres
“D” above - Use the mean between each particle bin for particlediameter:
0.3–0.5=0.40,0.5–1.0=0.75,1.0–2.5=1.75
2.5–5.0=3.75,5.0–10.0=7.50,10.0 and greater = 10.0
“s” above – We use the value of carbon (2.5).
“Kabs” above– we use the value of “1” for the absorption coefficient
