摘要
本文叙述了利用激光磁共振技术对NO气体污染源进行定量测量,研究了 NO 分子浓度与磁共振信号的关系,结果表明测量灵敏度可达0.7 ppm,可望制成具有高灵敏度、简便实用的激光磁共振NO 污染监测仪器。
We used the laser magnetic resonance spectroscopic method for the quantitative de-tection of NO molecules.The experimental results indicate that the dependence of LMR signalon the concentration of NO is linear within the low pressure range and the minimum detectablesensitivity is about 0.7 ppm.It is expected to form an instrument for the monitor of NO pollulantwith high sensitivity and considerable simplisity.
