摘要大气颗粒物浓度是大气污染监测中的一项重要指标。大气中的颗粒物，特别是PMl0及其以下颗粒物浓度的监测
一直是国内外专家关注的问题。本文提出一种采用振动原理在线测量颗粒物质量浓度的监测方法，替代了传统的离线监测
技术，提高了监测工作的实时性和正确性。

Abstract The amount of Airborne Particulate is an important index of monitoring the air pollution．The
particulates in the air，especially PMIO and those particulates‘diameter that are shorter than lO／jm are always the
hot topic among the specialists both inl foreign country and our own country．The on-line monitoring method of the
particulate‘s amount，based on the principle of vibration is put forward here．This method can be applied to replace
the traditional off-line monitoring method and tO improve the monitoring operation in the field of real—time and
accuracy．
Key words Airborne Particulate Vibration On-line Monitoring
