频率分析参数确定方法的探讨

Study on Determining Statistical Parameter in Frequency Analysis

频率分析中最关键的步骤是适线分析和区域平衡,其中适线分析首选离差平方和准则及相对离差平方和准则等数学分析方法。文中针对离差平方和准则和相对离差平方和准则适线中存在的问题提出了两参数优化方法,以此作为统计参数小幅度调整的辅助工具。

The key step in frequency analysis is curve-fit analysis and area balance, The first selection of curve-fit analysis is the mathematical analysis method of deviation square and criterion and relative deviation square and criterion. To counter the problems in the curve-fit of the deviation square and criterion and the relative deviation square and criterion, the method of two parameter optimzation is put forward in this paper, which can be used as the supplementary tool of slim adjustment of statistical parameter.
