  10. Based on the basic principle of wavelet analysis, multi - resolution analysis of signal in atomic clock is made. the coefficients of wavelet transform for synthesis atomic time, which are weighed and averaged at different wavelet scales, are obtained. then according to reconstruction theorem, multi - resolution synthesis time scale can be reconstructed. since the signal of atomic clock has been analysed by multi - resolution, we can use wavelet variance at different scales to weight and average the coefficients. thus either the difference in stability of different clock or the varying characteristic of the same clock at the different scale are all considered. finaly, this method is checked by the measured data from national timing serve center of shaanxi astronomy observatory. it confirmed that this technique, which is simple and practicable, is a new method of multi - resolution. from this method, the common characteristic of different clocks can be extracted. the stability of multi - resolution synthesis atomic time scale is obviously superior to that of other methods
