摘　　要：通过使用普通烟尘采样枪和低浓度烟尘采样枪两种采样方法,在不同采样时间采样,得出不同采样体积下的烟尘浓度的变化情况,从而选择出各自采集低浓度烟尘准确度高的最优采样体积。By using the two methods of sampling , that ordinary dust sampling gun and low concentration of smoke sampling gun,in different sampling time sampling, it is concluded that under different sampling volume changes of the smoke concentration,to choose the respective collection of low concentration of smoke with high accuracy, the optimal sampling volume.

关 键 词：低浓度烟尘 采样体积 采样枪
