原子钟噪声的多尺度分形特征

Multi-scale Fractal Characteristic of Atomic Clock Noise

将小波分析理论和分形理论结合起来，讨论原子钟噪声的多尺度分形特征。文中研究结构表明：在大尺度上，原子钟噪声具有某种拟周期变化；在小尺度上，原子钟噪声是完全随机的变化特征。原子钟的闪变噪声是一种分形随机的过程，具有对外界条件非常敏感的特点。

Multi-scale fractal characteristic in atomic clock noise is disscussed using wavelet theory and fractal theory. The result are indications that there iequasi-period variation at large scale in atomic clock noise. The random variation in atomic clock noise is presented at small scale. Flicker noise in atomic ccock is a fractal random process. It is high sensitive to outer condition.
