symmetric part meaning in Chinese

对称部分
对称部件

This article shows a new method to construct symmetric compacted orthogonal wavelet packet basis ： the original compacted orthogonal wavelet basis and scaling function are decomposed into symmetric and anti - symmetric parts respectively ， then we prove that three of four parts is also wavelet basis and another is scale function . we find it simple to process 1 - d signal . finally , by these results above , all the results above are applied to dsp
本文提出一种新的对称化方法，把一大类紧支集实值的非对称正交小波函数分解成对称和反对称两部分，并证明了其相应的两部分仍然构成对称和反对称的紧支正交小波基，而且我们发现尺度函数对称和反对称部分分别是某子空间的尺度函数和小波函数。
