摘　　要：介绍了激光质谱法的基本原理,利用已知苯和甲苯质荷比与飞行时间的关系,对质谱信号进行了精确定标.利用该方法对丙酮的多光子电离质谱进行了验证,得到了理想的实验结果.The principle of laser mass spectrum is introduced. The signal of mass spectrum is measured accurately by resorting to the relationship between the mass-to-charge ratio and the time-offlight in the field of benzene and toluene. As a matter of fact, ideal results in testing acetone have been achieved.

关 键 词：激光质谱法 质量数定标 飞行时间
