摘　　要：物质的发射和吸收光谱特征是区分物质种类的依据,准确确定光谱特征数值是物质分析的基础。以实测光谱数据为对象,运用高次多项式拟合的方法在全光谱范围内确定多个光谱曲线峰值的位置。通过与阈值截断后分组方法的对比分析显示,该方法适用性强、准确性高。The emission and absorption of spectral character by the substances is the basis of the types of substance discrimination, and to accurately determine the spectral character values is the basis of material analysis. In this paper we use the measured spectral data as the object, use the method of high-order polynomial fitting to determine in full spectral range the positions of multiple spectral curve peaks. Through the com- parative analysis with the method of grouping after threshold truncation, the method described in this paper is well applicable with high accuracy.
