    It is important and difficult to segment a time-frequency spectrogram due to its strong interference as well as serious overlap among targets and between targets and interference.An image entropy based fusion method for multi-scale morphological gradient image of a time-frequency spectrogram is presented.By combining that method with the marked watershed algorithm，a method for segmenting time-frequency spectrogram based on the multi-scale morphological gradient image and the marked watershed algorithm，is obtained.The experiment results show that it is more practical than the segmentation method which is based on single scale morphological gradient and marker watershed，and more accurate than Otsu method.

    To investigate the relationship between seed color and storability，the artificial aged Xiangzayou 631 seeds have been used as materials to study the germination and antioxidative physiological and biochemical variation.Results showed that the germination rate of both yellow and black rape seeds decreased significantly after accelerated artificial aging，and germination of yellow seeds decreased dramatically faster than the black. Superoxide radicle production，contents of hydrogen peroxide and MDA increased by 3 d accelerated artificial aging treatment，activities of antioxidative enzyme (SOD and CAT) increased obviously，and the content of AsA declined obviously.The comparison between two color seeds showed superoxide radicle production，hydrogen peroxide contents of the yellow seeds were much higher than those of the black seeds，but the SOD activity and AsA content of yellow seeds were much lower than those of the black seeds.It can be concluded that the black seeds of Xiangzayou 631 possess stronger storability due to greater contents of  nonenzymatic antioxidants.

    Multifractal detrended fluctuation analysis has been used to research the multifractal characteristics of stock returns of Jiugui Liquor Co. Ltd in Xiangxi Autonomous Prefecture.The evidence shows that the return series are multifractal both for time scales smaller than a week and for time scales larger than a week，it also verifies the fractal market hypothesis about stock.Furthermore，the sources of multi-fractal characteristic are analyzed through shuffling procedure and phase randomization procedure at different scales.For time scales smaller than a week，the main contribution of multifractality is long-range correlations.For time scales larger than a month，both fat-tail distribution and long-range correlations play important roles in the contribution of multifractality.
