英语翻译
细颗粒物又称细粒、细颗粒.大气中粒径小于2μm（有时用小于2.5μm,即PM2.5）的颗粒物（气溶胶）.虽然细颗粒物只是地球大气成分中含量很少的组分,但它对空气质量和能见度等有重要的影响.细颗粒物粒径小,富含大量的有毒、有害物质且在大气中的停留时间长、输送距离远,因而对人体健康和大气环境质量的影响更大.随着我国越来越多的人们越来越关注自己所生活环境的空气质量,PM2.5在我国也被越来越重视,逐步建立起测量站点.
本课题是采用51单片机设计的PM2.5测量仪方案.PM2.5测量仪由硬件和软件两部分组成.硬件部分由51单片机、传感器模块、显示模块组成.本课题主要研究软件部分的设计——即在Keil C51软件开发环境下利用C语言编写的程序处理传感器模块传来的数据,并通过显示模块显示出来.

Fine particulate matter also called fine grained, and fine particles. Atmosphere particle size is smaller than 2 microns (sometimes used is less than 2.5 microns, namely PM2.5) of particulate matter (aerosol). Although fine particulate matter is only few components content of earth's atmosphere, but it has a important influence on air quality and visibility, etc. Fine particle size small, rich in a lot of poisonous and harmful substances in the atmosphere and stay long time, conveying distance, so for human health and the impact of atmospheric environment quality is greater. Along with our country more and more people are paying more attention to their living environment of air quality, PM2.5 has been pay more and more attention to in our country, and gradually established a measurement site.
This topic is to use 51 single-chip design of PM2.5 measuring instrument. PM2.5 measuring instrument is made up of hardware and software two parts. The hardware part consists of 51 single-chip microcomputer, sensor module, display module. This topic main research the design of the software part - that is, under the environment of Keil C51 software development using C language program to deal with data from the sensor module, and through the display module display.
