1Probabilistic forecasting based on ensemble forecasts and EMOS method for TGR inflow显示文摘Probabilistic inflow forecasts can quantify the uncertainty involved in the forecasting process and provide useful risk information for reservoir management.This study proposed a probabilistic inflow forecasting scheme for the Three Gorges Reservoir(TGR)at 1-3 d lead times.The post-processing method Ensemble Model Output Statistics(EMOS)is used to derive probabilistic inflow forecasts from ensemble inflow forecasts.Considering the inherent skew feature of the inflow series,lognormal and gamma distributions are used as EMOS predictive distributions in addition to conventional normal distribution.Results show that TGR's ensemble inflow forecasts at 1-3 d lead times perform well with high model efficiency and small mean absolute error.Underestimation of forecasting uncertainty is observed for the raw ensemble inflow forecasts with biased probability integral transform(PIT)histograms.The three EMOS probabilistic forecasts outperform the raw ensemble forecasts in terms of both deterministic and probabilistic performance at 1-3 d lead times.The EMOS results are more reliable with much flatter PIT histograms,coverage rates approximate to the nominal coverage 89.47%and satisfactory sharpness.Results also show that EMOS with gamma distribution is superior to normal and lognormal distributions.This research can provide reliable probabilistic inflow forecasts without much variation of TGR5s operational inflow forecasting procedure.Yixuan ZHONG Shenglian GUO Feng XIONG Dedi LIU Huanhuan BA Xushu WU 2020Frontiers of Earth Science2020,14,1:3

4Decoration of C_(60) nanorods with nickel and their magnetic properties显示文摘We studied the coating of C60 nanorods with nickel by electroless plating method and investigated their magnetic properties. The morphology and structure of the nickel layer coated on C60 nanorods were characterized by transmission electron microscopy (TEM), energy-dispersive X-ray spectroscopy (EDX), X-ray diffraction (XRD) and Raman spectroscopy. The coated nickel is in the form of nano-sized crystals and becomes a continuous layer as reaction time increases. The hysteresis loop shows a super paramagnetic characteristic similar to that of nanometer-sized nickel particle. These results suggest that the average size of nickel particles on C60 rods is below 10 nm. Our study has shown that electroless plating is an efficient and simple method for coating C60 nanorods with nickel.CHEN Ao LIU BingBing HOU YuanYuan WEN GeHui LIU DeDi LU ShuangChen LI ZePeng LI XiangLin ZOU YongGang ZOU Bo LI DongMei CUI Tian ZOU GuangTian 2009Chinese Science Bulletin2009,54,14:1
