摘要
基于C#平台以及数字化多道分析器,设计了气溶胶α能谱测量分析软件。软件集成了最小二乘移动平滑法、二阶导数及函数拟合剥谱法等算法,可完成α能谱进行自动分析,并计算出环境中的特征能量的α放射性物质的含量,采用sqlite建立数据库存储测量结果。软件采用RS232通信接口方式,实现数据的实时传输,具有数据光滑、自动寻峰、谱漂校正、峰面积计算、活度计算等功能,最终给出气溶胶的活度信息。
Based on C#and digital multichannel analyzer,the software for measuring and analy-zing aerosol a spectrum is designed.The software integrates the least square moving smoothing method,the second derivative and the function fitting spectrum stripping method and other algo-rithms.It can automatically analyze the alpha spectrum and calculate the content of alpha radioac-tive material which radiates specific energy in the environment.The sQLite database is used to store the measurement results.RS232 communication interface is used to realize real-time data transmission.The software includes data smoothing,automatic peak searching,spectral drift cor-rection,peak area calculation,activity calculation and other functions.Finally,the aerosol activity information is given.
