| 2 | Suppressing Al2O3 nanoparticle coarsening and Cu nanograin growth of milled nanostructured Cu-5vol.%Al2O3 composite powder particles by doping with Ti显示文摘Both the coarsening of Al_2O_3 nanoparticles and the growth of Cu nanograins of mechanically milled nanostructured Cu-5 vol.%Al_2O_3 composites with, and without, trace amounts of Ti during annealing at973 K for 1 h were investigated. It was found that doping with a small amount of Ti(e.g. 0.2 wt%) in a nanostructured Cu-5 vol.%Al_2O_3 composite effectively suppressed the coarsening of Al_2O_3 nanoparticles during exposure at this temperature. Further, the Ti addition also prevented the concomitant abnormal growth of the copper grains normally caused by the coarsening of the Al_2O_3 nanoparticles. Energy dispersive X-ray spectroscopy analysis of the Al_2O_3 nanoparticles in the annealed Cu-5 vol.%Al2 O3-0.2 wt%Ti sample suggested that the Ti atoms either diffused into the Al_2O_3 nanoparticles or segregated to the Cu/Al_2O_3 interfaces to form Ti-doped Al_2O_3 nanoparticles, which was more stable than Ti-free Al_2O_3 nanoparticles during annealing at high homologous temperatures. | Dengshan Zhou Hongwei Geng Wei Zeng Deliang Zhang Charlie Kong Paul Munroe | 2017 | Journal of Materials Science & Technology2017，33，11： | 1 |
| 3 | Aeolian Activities and Protective Effects of Artificial Plants in Re-vegetated Sandy Land of Qinghai Lake,China显示文摘Land desertification and aeolian activity are currently the greatest threats to alpine ecological environments and are also the primary challenges of desertification control and ecological restoration projects.Afforestation of sandy lands around the Qinghai Lake in China has effectively controlled the desertification of this watershed.However,certain issues remain which challenge its overall success,including lack of diverse biological species and poor theoretical understanding of aeolian processes,such as controlling wind-sand flow in relation to complex alpine ecological factors.Therefore,to help improving afforestation techniques,this research focused on Hippophae rhamnoides,Salix cheilophila,Pinus sylvestris,Populus simonii and Artemisia desertorum vegetation implanted in the mobile dunes on the eastern shore of Qinghai Lake.Aeolian transport characteristics and annual changes to community ecological factors from 2010–2016 were monitored in comparison with uncontrolled sand dunes.Based on simultaneous observations using gradient anemometers and sand samplers,it was found that the aeolian activities exhibited the following features:1)In re-vegetated lands,the logarithmic growth of wind speed was disrupted by the wind speed amplification in the middle and high layers and wind speed reduction in the low layers,while vegetation had significant wind-breaking(>37%)and sand-fixing(>85%)effects in 2016.2)Wind speeds in re-vegetated lands and mobile dunes showed a linear correlation,especially in lower layers of H.rhamnoides and S.cheilophila,while sand transport in re-vegetated land increased linearly or exponentially with increasing wind speed.3)The four artificial shrubs and forests had greater sand deposition with intensities of 280–860 t/(ha·yr),largely concentrated during winter and spring which accounted for 60%–85%of the annual cycle,while A.desertorum experienced significant root undercutting;and 4)Intensity of aeolian activity in re-vegetated lands,except for A.desertorum,was significantly negative with respect to plant growth structure,community cover,topsoil moisture,and regional precipitation.Overall,these five sand-binding species produced optimistic wind-sand protection effects for the alpine sandy lands,which relied on the plants’physical disturbance of wind-sand flow during the early stages of community development.In comparison,H.rhamnoides and S.cheilophila individually maintained stable wind-sand protection effects,while P.sylvestris and P.simonii were better in mixing with other shrubs and herbs to achieve a comprehensive ecological system for future control of aeolian activity. | WU Wangyang ZHANG Dengshan TIAN Lihui ZHANG Hongwei | 2020 | Chinese Geographical Science2020，30，6： | 1 |

| 10 | Morphological change and migration of revegetated dunes in the Ketu Sandy Land of the Qinghai Lake,China显示文摘Alpine revegetated dunes have been barely researched in terms of morphological change and migration within its regional aeolian environments. To reveal the sand-fixing and land-reforming mechanisms of artificial vegetation, we observed the morphology and migration of four dunes with four revegetated types(Hippophae rhamnoides Linn., Salix cheilophila Schneid., Populus simonii Carr., and Artemisia desertorum Spreng.) using unpiloted aerial vehicle images and GPS(global positioning system) mapping in 2009 and 2018. Spatial analysis of GIS(geographic information system) revealed that the revegetated dunes exhibited a steady progression from barchan dune shapes to dome or ribbons shapes mainly through knap planation, wing amplification, and slope symmetrization. Generally, conditions of northern aspects, smaller slope degree, and larger altitude of unvegetated dunes would suffer more serious wind erosion. The southward movement of dune wings with a migration speed of 2.0–5.0 m/a and the alternating motion of sand ridges in eastwestern directions led greater stability in revegetated dunes. The moving distances of revegetated dunes remarkably changed in patterns of quadratic or linear function with depositional depth. Compared with unvegetated dunes, the near-surface wind velocity of revegetated dunes decreased by 20%–30%, which led to heavy accumulation in low-flat dunes and erosion in high-steep dunes, but all vegetation species produced obvious sand-fixing benefits(100%–450% and 3%–140% in the lower and higher dune scales of revegetated dunes, respectively) with decreasing sand transport rates and increasing coverages. In practice, the four vegetation species effectively anchored mobile dunes by adapting to regional aeolian environment. However, future revegetation efforts should consider optimizing dune morphology by utilizing H. rhamnoides as a pioneer plant, S. cheilophila and P.microphylla in windward and northward dune positions, and A. desertorum in a sand accumulative southward position. Also, we should adjust afforestation structure and replant some shrub or herbs in the higher revegetated dunes to prevent fixed dune activation and southward expansion. | WU Wangyang ZHANG Dengshan TIAN Lihui SHEN Tingting GAO Bin YANG Dehui | 2023 | Journal of Arid Land2023，15，7： | 1 |
| 11 | On the role of climate in desertification of the Sahel Belt显示文摘s—Sahel in West Africa is the most seriously desertified zone in the world. In this paper, the impact of climate on desertification in Sahel is discussed. The climate can exert an impact on desertification in the zone either individually or in conjunction with excessive human economic activities. The rapid desertification in the zone over the last several decades, however, is mainly caused by excessive human economic activities. | DING Dengshan MA Jongli PEN Buzhuo RUI Fuhong ZHANG Hong ZHANG An Department of Urban and Resources Science, Nanjing University, Nanjing 210093 CHINA | 1998 | Journal of Geographical Sciences1998，8，4： | 1 |

| 14 | Optimal Military Spending,Trade and Stochastic Economic Growth显示文摘Based on the procedure of dynamic programming,this paper investigates the military spending,trade and wealth accumulation in a stochastic endogenous economic growth model.For the Cobb-Dauglas utility function,explicit solutions of the optimal problem of the home country are obtained.Meanwhile,the optimal consumptions of domestic goods and foreign goods,the share of domestic capital stock and foreign bond holdings are derived explicitly.The comparative dynamic analysis shows that when intertemporal substitution in consumption is relative elastic,economic growth has a positive correlation with foreign military spending,has a negative correlation with variance of foreign military spending,and has a positive correlation with variance of capital or bonds if capital and bonds yields the same benefits.However,in the case of inelasticity,variance of foreign military spending may stimulate or weaken economic development. | WANG Dengshan WANG Yan | 2016 | Journal of Systems Science & Complexity2016，29，3： | 1 |
