摘　　要：本文详细介绍了一种全新的污染物测试方法———激光质谱法的原理和特点。我们应用这一方法对机动车尾气进行了初步探测 ,得到了 2 6 6nm激光作用下汽车尾气的激光电离质谱图 。In this paper, the principle and features of a new pollution monitoring method--laser mass spectrometry were described in detail. The method was used to preliminarily measure the vehicle emission, and multiphoton ionization time of flight mass spectrum of the exhaust gas of a car was obtained. The plot between the operating conditions of engine and benzene and its derivative pollutant emission concentration was detected on line.
