摘要
低粉尘浓度气体中细颗粒物(PM2.5)的测量用称重法和计数法都有困难,文章提出用稀释气体降低含尘浓度后,用激光尘埃计数器测量其中细颗粒物的数量,计算出质量浓度的办法。
It is difficult to measure the fine particulate matter （PM2.5） in gas of low dust concentration by the weighing process and counting process. After the paper puts forward to reduce the low contained dust concentration by diluting the gas, the quantity of fine particulate matter is measured by using the laser dust counter, and quality concentration is counted.
