The CeO2-V2O5-WO3/TiO2 （CeO2-VWT） catalysts were prepared by one-step and two-step impregnation methods. The effects of different loading of CeO2 and different preparation methods on De-NOx activity of catalysts had been investigated. CeO2 helped to improve the De-NOx activity and sulfur resistance. The optimal loading of CeO2 was 3% with the De-NOx efficiency reached 89.9% at 140℃. The results showed that the De-NOx activity of 3% CeO2-VWT catalysts by one-step method was the same as two-step method basically and reached the level of industrial applications, the N2 selectivity of catalysts was more than 99.2% between 110℃ and 320℃. In addition, CeO2 promoted the oxidation of NO to NO2, which adsorbed on the Lewis acid site （V5＋-O） to form V5＋-NO3 and inspired the fast SCR reaction. Not only the thermal stability but also the De-NOx activity of catalysts decreased with excess CeO2 competed with V2O5. Characterizations of catalysts were carried out by XRF, BET, XRD, TG and FT-IR. BET showed that the specific surface area of catalysts decreased with the loading of CeO2 increased, the active components content and specific surface area of catalysts decreased slightly after entering SO2. Ammonium sulfate species were formed in poisoned catalyst which had been investigated by XRF, BET, TG and FT-IR. The largest loss rate of weight fraction was 0.024%.℃-1 at 380℃ 390℃, which was in accordance with the decomposition temperature of NH4HSO4 and （NH4）2SO4,

In this study, the observed CMORPH precipitation data from 1998 to 2015 are used to analyze diurnal variation of global precipitation. The results reveal that the strong diurnal signals of precipitation occur over equatorial continental areas where the annual precipitation centers are located. The phase of diurnal variation of global precipitation reveals a distinct land-sea contrast with nocturnal peaks at sea and afternoon maxima over continents. The analysis of six selected area reveals that precipitation peak over equatorial land areas occur in afternoon and maximum diurnal signals appear in autumn or winter. Eastern equatorial Intertropical Convergence Zone(ITCZ) barely shows diurnal signals in the entire year. Precipitation over Sichuan Basin and northwestern Pacific shows nocturnal peak and the maximum diurnal amplitude in summer. Precipitation over coastal areas off eastern China shows an afternoon peak and the largest diurnal amplitude in summer.
