本文提出建立发射光谱谱线参数西级数据库的设计方法,第一级为“分析线参数数据库”,它统计收录了75种元素的约350条常用灵敏线及特征线的波长、检测限等参数;第二级为收有约一万一千条谱线的“光谱干扰参数数据库”,它由每条分析线两侧的波长和相对强度等参数联接、排序、压缩而成。本法能在原来十分庞大的谱线信息中提取出简约却有效的数据库。而微机检索系统由于采用了两级数据库结构、菜单驱动和索引技巧,故可快速方便地提供分析线及相应光谱干扰的有关参数。
In this paper, a design method of establishing a west-level database of emission spectrum parameters is proposed. The first stage is “Analysis of line parameter database”, which collects about 350 commonly used sensitive lines of 75 kinds of elements and wavelengths of characteristic lines, detection limits and other parameters ; The second level is “spectral interference parameter database” with about 11,000 spectra, which is connected, sorted and compressed by parameters such as wavelength and relative intensity on both sides of each analysis line. This method can be extracted from the original very large spectral information is simple but effective database. The computer retrieval system due to the use of a two-tier database structure, menu-driven and indexing techniques, it can quickly and easily provide the analysis line and the corresponding spectral interference parameters.
