摘　　要：与常规的白细胞亚分类方法不同,提出一种新型的白细胞分类方法,该方法采用希尔伯特黄变换将细胞光学信号自适应分解,并利用支持向量机构建细胞亚分类模型进行识别分类。实验结果:白细胞亚类可比性和相关性达到了血液分析仪行业标准要求。该方法为细胞信号分析以及亚分类提供了新思路。In order to improve the accuracy of sub-classification results,a new classification method of cell recognition is proposed.In this method,the signal is decomposed into multiple intrinsic mode functions by HHT.Then,the average intensity and spectral centroid of the functions are calculated as the eigenvector.Finally,the classification mode of leukocyte subgroup is constructed by using the support vector machine.Results：leukocyte comparability and relativity achieve the standards of blood analyzer industry.This method provides a new idea for cell signal analysis and sub classification.
