二、分析了活动部件周期调制特征产生机理和频谱结构特点，并通过建立通用仿真模型描述直升机旋翼，螺旋桨以及喷气引擎压缩叶片的动态电磁散射现象；针对活动部件周期调制，阐述了自相关特征提取和子波包特征空间变换的基本原理；并利用模糊模式比较完成基于空中目标活动部件周期调制特征的分类识别试验，给出识别结果。

The present study demonstrates that caffeic acid phenethyl ester, a major component of honeybee propolis, enhanced ATRA-induced granulocytic differentiation in HL-60, a human promyelocytic cell line. The differentiation was assessed by Wright-Giemsa stain, nitroblue tetrazolium reduction, and membrane differentiation marker CD11b.
