摘　　要：目的　研究小波分析结合复倒谱处理血膜中中性粒细胞分布数据信号的新方法及临床意义。方法　利用“虚拟盒计数法”方法采集血膜中的细胞分布数据信号 ,然后进行小波变换结合复倒谱分析方法处理。结果　提出血膜中细胞分布状态的“密集子”新概念。计算出小波变换复倒谱主极大值 ,并以此作为不同情况下血膜中中性粒细胞分布“密集子”间距的准确参数。结论　方法简单 ,能较好的反映血膜中细胞分布状态的微观组织结构特征 ,是血膜中细胞“密集子”Objective To explore new method and its clinical significance, i.e. using the wavelets transform in combination with complex cepstrum to study neutrophil distribution by monitoring their cell membrane signals in blood. Methods 'Virtual Box count' method was used to collect blood cell membrane signals, which was subsequently processed using the wavelets transform combined with the complex cepstrum analysis method. Results Based on data analysis, a new concept using 'concentrated group'of blood cell membrane for studying states of blood cell distribution was established. This enabled to calculate the main maximum of wavelets transform in combination with the complex cepstrum, which served as an accurate parameter of the 'concentrated group' interval of neutrophil distribution in the blood under the different circumstances.Conclusion This method is simply, can better reflect blood cell membrane microstructural characteristics of cell distribution state. It is a effective method to express the characteristics of the 'concentrated group interval' in the blood cell membrane.
