中文摘要：
介绍了自主开发的LIBS谱线识别软件,基于LabVIEW虚拟仪器开发平台,利用二次微商和阈值判定对LIBS谱数据进行降噪、寻峰,并通过参考NIST原子光谱数据库,确定了多种常见元素的特征波长,可以自动识别元素谱线,实现了对样品所含元素种类的定性分析。该软件系统定性分析元素简单、快捷,具有一定的实用性及推广价值。
英文摘要：
Self-designed identifying software for LIBS spectral line was introduced.Being integrated with LabVIEW,the software can smooth spectral lines and pick peaks.The second difference and threshold methods were employed.Characteristic spectrum of several elements matches the NIST database,and realizes automatic spectral line identification and qualitative analysis of the basic composition of sample.This software can analyze spectrum handily and rapidly.It will be a useful tool for LIBS.
