同时研究了奇周期最佳几乎二进序列偶的变换性质和频谱特性，给出了一些组合允许条件。

The transformation features and Fourier spectrum of odd-periodic perfect almost binary sequence pair are studied. Some combined admissibility conditions are also given out.

利用小波变换这一工具，可以在化简时保留奇性的主要部分，使所得的结果从奇性分析的观点看来更为精确。

Using the method of wavelets transform, the main terms in singularities are retained in simplification. So the result is more accurate in a point view of singularity analysis.
