摘要:
This paper based on the monthly precipitation data of 9 surface meteorological stations in the Hengyang basin for 53 years (1960 to 2012), by using the methods of Morlet wavelet transform and Mexican hat wavelet analysis, the multi-time scales of precipitation of the Hengyang basin has analyzed. The results show that during the study period, the Hengyang basin has different time scales during the year and seasonal precipitation. The main periodic variation characteristics of quasi 24a, quasi 10a and quasi 3a time scales are existed in annual precipitation. And on the quasi 24a scale, the mutation points are 1963a, 1970a, 1977a, 1990a and 2004a. The characteristic period of spring and summer, or autumn and winter precipitation have highly similarity. And we speculate that the precipitation in the Hengyang basin tends to be less than normal in some time after 2012a.

摘要:
We demonstrate a novel and universal strategy to significantly boost electrochemical performances of conducting polymer-based flexible supercapacitors via the relatively facile electrodeposition of Mo-Ni-P compounds. The fabricated Mo-Ni-P@polyaniline (PANI)@carbon fiber cloth (CFC) sandwiched hybrid, for instance, delivers 94.6% of specific capacitance retention from 1 to 40 mA cm(-2) and 92.3% of specific capacitance retention at a high current density of 40 mA cm(-2) after 2000 cycles, much greater than 56.8% and 58.3% for the uncoated PANI@CFC with Mo-Ni-P, respectively. With increasing the numbers for repeatedly alternate coating PANI and Mo-Ni-P layer by layer, the specific capacitances rise almost linearly. Simultaneously, the capacitance retentions maintain high levels at 40 mA cm(-2) after 2000 cycles. A remarkable decrease in the charge transfer resistance and a markedly enhanced hydrophilicity with coating Mo-Ni-P on the surface of PANI@CFC can be found, which can greatly facilitate the electron and electrolyte ion transfer processes and thereby bring with it improved supercapacitive performance. Likewise, the supercapacitive performances of polypyrrole and poly(3,4-ethylenedioxythiophene) can be significantly enhanced in comparison with their Mo-Ni-P uncoated counterparts.
