| 1 | The hydrological linkage of mountains and plains in the arid region of northwest China显示文摘Mountain regions supply a large amount of fresh water for the people in arid and semiarid regions, however, there is great uncertainty of the water quantification from mountains to lower areas. In order to assess the hydrological significance of mountains and the hydrological linkage of mountains and plains, the measured and simulated hydrological data of the arid region in northwest China were used in the present research which followed a catchment-based approach. Firstly, the Heihe River Basin, a well-documented area, was selected as a specific watershed to reveal the hydrological relationship between highlands (mountains) and lowlands (plains); and then, the significance and disproportion of mountain runoff of 8 river basins as cases in the arid region of northwest China were analyzed and compared following the above analysis. The results of the study showed that the proportion of mountain runoff in total basinal runoff (PMR) of most rivers is above 50%. The PMR are between 50%-95% in the rivers originated in the northern slope of the Tianshan Mountains where the aqueous vapor is relatively sufficient. And that, almost all the flow of the rivers originating from the Qilian Mountains, the southern slope of the Tianshan Mountains, and the northern slope of the Kunlun Mountains come from mountain regions. Also the PMR gradually increases from west to east in northwest China. The hydrological significance and disproportion of mountains water in the arid region of northwest China were given a systematic and thorough assessment, and the results could give potential guides for the scientific utilization of water resources in these regional areas for relieving the more and more serious shortage of water resources due to climate warming and population expansion. | QIN Jia DING YongJian YANG GuoJing | 2013 | Chinese Science Bulletin2013，58，25： | 3 |
| 2 | Annealing Effect of ZnO on the Performance of Inverted Organic Photovoltaic Devices显示文摘ZnO nanoparticles films were prepared via sol-gel process and incorporated into inverted organic photovoltaic devices with a structure of ITO/ZnO/P3HT:PCBM/MoO_3/Ag,in which ZnO film served as an electron selective layer.The effects of annealing temperature of ZnO film on the device performance were investigated.When the annealing temperature was 300 ℃,a well-arranged ZnO thin film was obtained,and the optimized device had doubled short circuit current density(J_(SC)) and seven-fold higher power conversion efficiency(PCE)compared to the devices without ZnO film.This improvement could be attributed to the enlarged interfacial area of ZnO/active layer and better energy band matching which causes an efficient electron extraction and a decreased interface energy barrier.At particularly high annealing temperature,dramatically increased sheet resistance of indium tin oxide(ITO) was found to cause PCE deterioration.Our finding indicates that it is highly important to investigate both morphology and electrical effects for understanding and optimizing organic photovoltaic(OPV) performance. | Wenjing Qin Guojing Ding Xinrui Xu Liying Yang Shougen Yin | 2014 | Journal of Materials Science & Technology2014，30，2： | 0 |
