| 摘 要： | 目的 探讨某型号个体采样器采样过程中流量变化规律.方法 分别测量不同型号、不同规格炭管管口水平放置、管口向上竖直放置和管口向下竖直放置3种情况下,不同采样时间的流量,比较流量的变化规律.结果 无论何种炭管及如何放置,采样流量均随采样时间的增加而增加;炭管管口向下放置时,流量随时间的增加速度稍高于其他两种情况;在炭管不同...

| Abstract: | Objective To explore the changing regularity of flow-rate of a certain type personal sampler during sampling process.Methods The flow-rates at different sampling time were measured when the carbon tubes from different sampler types and different specifications were pointing horizontally,vertically upward,and vertically downward for three minutes.The changing rule of the flow-rate was compared.Results No matter which types of the carbon tube were used and how they were placed,the volumetric flow sampled incr... |
