摘　　要：自行研制了一台大气气溶胶飞行时间激光质谱仪(ATOFLMS),它可以实时地对气溶胶单粒子进行物理和化学特性分析,是大气气溶胶研究和测量的一个有力工具。该仪器在运行过程中将产生海量的实验数据,对这些数据的实时、自动处理、提取有价值的信息是整机系统的关键之一。我们基于面向对象的技术为它开发了配套计算机软件MS-ACS,该软件能够自动地实现气溶胶单粒子的粒径和化学成分信息的实时采集、分析和存储功能。An aerosol time-of-flight laser mass spectrometry （ATOFLMS） had been designed in our lab. ATOFLMS is a technique that can be used to determine the physical and chemical characteristics of individual aerosol particles in real time. It is a powerful tool for researching and monitoring of atmospheric aerosol particles. ATOFLMS generates large amount of data during the process period. How to process these data and extract valuable information is one of the key problems for the ATOFLMS. We developed application software for it based on object oriented programming method. The application software can perform automatically to acquire, process and store the data of size and resolve chemical composition of individual aerosol particles in real time.
