利用小波分析原理对实测的振动力场作用下LDPE、LLDPE熔体挤出胀大进行Daubechies小波分析，发现挤出机螺杆振动的振幅、频率分别对聚合物熔体挤出胀大变化的周期性特征产生不同影响，且使得挤出制品结构更致密，材料性质更均匀，品质更高。

By means of Daubechies wavelet analysis, the time-frequency of LDPE and LLDPE melt extrusion swell under the vibration force field was analyzed. Results show that the amplitude and frequency can influence the periodic charac-teristics of polymer melt extrusion swell respectively. Applying vibration, the material properties become more uniform, the product structure, more compact, and the quality, higher.
