| 摘要: |
| 提出了一种可伸缩延长气体采样装置，并将其与现场气体监测仪器配套使用。初步考察了延长采样装置中Teflon采样管长度对现场监测结果可能产生的影响，并对监测站实验室楼顶废气排出筒气体进行了实际样品监测。结果表明，该装置可有效提高现场应急监测的安全防护保障效果，增加可监测区域范围，使现场应急监测工作能够为突发性环境污染事件的处置提供更多技术支持。 |

| Abstract: |
| A simple gas sampling device with telescopic extension function was provided for use together with air monitoring devices on site. Initial investigation was given to the influence of the length of the Teflon sampling pipe on the monitoring results. The gas from the exhaust funnel of a laboratory building was monitored with this device subsequently. The results showed that such device could prompt safety protection and increase areas for efficient monitoring in emergency monitoring on site， which served to provide more technical support for abrupt environmental pollution accidents. |
