| 摘 要： | 氢氧自由基（ＯＨ）在对流层大气化学中起着重要的作用，因此，对其浓度的测量具有重要意义。本文利用气体扩张激光诱导荧光技术（ＦＡＧＥ）建立了ＯＨ测定系统，对其进行了标定，得到归一化荧光信号（Ｓ）与ＯＨ自由基浓度的较好的相关关系，并对可能存在的干扰进行了分析。

| Abstract: | Hydroxyl radical(OH) plays a key role in the tropospheric chemistry,so the measurement of its concentration is very important.In this paper,an OH detection system was established based on the LIF (Laser Induced Fluorescence)technique.A calibration system was described,and the correlation between the normalized signal( S ) and OH concentration was relatively good ( R 2=0.987).The interferences probably existing in the system were discussed. |
