| 摘 要： | 在拓展分形维数概念的基础上，提出曲线的点盒维数定义，并以此构筑判峰算法，发展了一种新的谱峰检测理论及实现途径．与现有谱峰检测技术相比，该算法具有判据阈值设定简单可靠、适应范围广、谱峰识别准确等显著特点．实践表明，这种新的谱峰检测法能满意地用于色谱、光谱等仪器分析数据的自动处理．

| Abstract: | The new spectral peak\|detection theory and its algorithm proposed in this paper is based on the Point\|box\|dimension, a new concept and criterions derived from Fractal Dimension. Compared with the current spectral peak\|detection techniques, it has the advantages of easy setting of criterions, strong adaptability and high accuracy. Experiment results showed that this new method is very suitable for analytical data processing of spectrum and chromatogram. |
