摘　　要：目的:以同一种吸收介质(水)通过三种不同吸收管根据不同的时间进行采样,最后得出在相同条件下,不同时间、不同采样流量其吸收液的损失效率变化趋势,以给实验室在制定现场吸收液的长时间采样的选择提供依据;方法:分别对三种不同吸收管的吸收液进行采样,记录每15 min其采样的损失量,并计算损失效率,直至吸收液损失效率达10%以上,并对三种不同吸收管在不同时间损失效率进行统计分析;结果:随着采样流量的增加,其损失效率增长越快,采样流量固定的情况下,其损失效率与采样时间成线性关系;结论:损失效率的研究有助于实验室在制定吸收液长时间采样时提供依据,避免过长时间的采样导致吸收液损失效率过大,从而影响检测结果。Objective:The same absorption medium(water)is sampled through three different absorption tubes according to different time.Finally,the change trend of absorption liquid loss efficiency under the same conditions,different time and different sampling flow rate is obtained,so as to provide the basis for the laboratory to select the long-time sampling of on-site absorption liquid;Methods:The absorption liquid of three different absorption tubes were sampled,and the loss amount was recorded every 15 minutes,and the loss efficiency was calculated until the failure rate of absorption liquid loss was more than 10%;Results:With the increase of sampling flow,the loss efficiency increases faster.When the sampling flow is fixed,the loss efficiency is linearly related to the sampling time;Conclusion:The research on the loss efficiency is helpful for the laboratory to provide the basis for the long-time sampling of the absorption solution,so as to avoid the excessive loss efficiency of the absorption solution caused by the long-time sampling,which will affect the detection results.
