摘　　要：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。An efficient method is presented for the design of the two order emission spectral line parameter database. One is 'analytical line parameter database', it contains the wavelength, detection limit of about 350 lines of 75 kinds of elements; and the other is 'spectral interference parameter database', it first collects the wavelength and relative indensity of lines that appear near each analytical lines, and then those about 11000 lines are linked, sorted and compressed. This method can obtain a simple but useful database from quite a number of spectral line information. Using the retrieval system introdeced the technique of two order database structure, menu drive and index location, we can quickly and easily get the parameters of analytical line and its spectral interference on PC/XT computer.
