| 1 | Soil exchangeable base cations along a chronosequence of Caragana microphylla plantation in a semi-arid sandy land,China显示文摘As a pioneer leguminous shrub species for vegetation re-establishment,Caragana microphylla is widely distributed in the semi-fixed and fixed sandy lands of the Horqin region,North China.C.microphylla plantations modify organic carbon(SOC),nitrogen(N) and phosphorus dynamics,bulk density and water-holding capacity,and biological activities in soils,but little is known with regard to soil exchange properties.Variation in soil exchangeable base cations was examined under C.microphylla plantations with an age sequence of 0,5,10,and 22 years in the Horqin Sandy Land,and at the depth of 0-10,10-20,and 20-30 cm,respectively.C.microphylla has been planted on the non-vegetated sand dunes with similar physical-chemical soil properties.The results showed that exchangeable calcium(Ca),magnesium(Mg),and potassium(K),and cation exchange capacity(CEC) were significantly increased,and Ca saturation tended to decrease,while Mg and K saturations were increased with the plantation years.No difference was observed for exchangeable sodium(Na) neither with plantation years nor at soil depths.Of all the base cations and soil layers,exchangeable K at the depth of 0-10 cm accumulated most quickly,and it increased by 1.76,3.16,and 4.25 times,respectively after C.microphylla was planted for 5,10,and 22 years.Exchangeable Ca,Mg,and K,and CEC were significantly(P<0.001) and positively correlated with SOC,total N,pH,and electrical conductivity(EC).Soil pH and SOC are regarded as the main factors influencing the variation in exchangeable cations,and the preferential absorption of cations by plants and different leaching rates of base cations that modify cation saturations under C.microphylla plantation.It is concluded that as a nitrogen-fixation species,C.microphylla plantation is beneficial to increasing exchangeable base cations and CEC in soils,and therefore can improve soil fertility and create favorable microenvironments for plants and creatures in the semi-arid sandy land ecosystems. | YuGe ZHANG ZhuWen XU DeMing JIANG Yong JIANG | 2013 | Journal of Arid Land2013，5，1： | 11 |
| 2 | X-BAND CIRCULARLY POLARIZED RECTENNAS FOR MICROWAVE POWER TRANSMISSION APPLICATIONS显示文摘Circularly polarized rectennas operating at X-band are studied in this paper. The quasi-square patches fed by aperture coupling are used as the circularly polarized receiving antennas, which are easily matched and integrated with the circuits of rectennas. The double-layer structure not only minimizes the size of the rectennas but also decreases the effects of the circuits on the an- tenna. The receiving elements have broader bandwidth and higher gain than the single-layer patches. Two rectennas operating at 10GHz are designed, fabricated and measured. The voltage of 3.86V on a load of 200? is measured and a high RF-DC conversion efficiency of 75% is obtained at 9.98GHz. It is convenient for this kind of rectennas to form large arrays for high power applications. | Yang Xuexia Xu Junshu Xu Deming Xu Changlong | 2008 | Journal of Electronics(China)2008，25，3： | 7 |
| 3 | Characteristics of oxygen consumption of coal at programmed temperatures显示文摘Oxygen consumption is an important index of coal oxidation.In order to explore the coal-oxygen reaction,we developed an experimental system of coal spontaneous combustion and tested oxygen consumption of differently ranked coals at programmed temperatures.The size of coal samples ranged from 0.18~0.42 mm and the system heat-rate was 0.8℃/min.The results show that, for high ranked coals,oxygen consumption rises with coal temperature as a piecewise non-linear process.The critical coal temperature is about 50℃.Below this temperature,oxygen consumption decreases with rising coal temperatures and reached a minimum at 50℃,approximately.Subsequently,it begins to increase and the rate of growth clearly increased with temperature.For low ranked coals,this characteristic is inconspicuous or even non-existent.The difference in oxygen consumption at the same temperatures varies for differently ranked coals.The results show the difference in oxygen consumption of the coals tested in our study reached 78.6%at 100℃.Based on the theory of coal-oxygen reaction,these phenomena were analyzed from the point of view of physical and chemical characteristics,as well as the appearance of the coal-oxygen complex.From theoretical analyses and our experiments,we conclude that the oxygen consumption at programmed temperatures reflects the oxidation ability of coals perfectly. | QI Xuyao WANG Deming ZHONG Xiaoxing GU Junjie XU Tao | 2010 | Mining Science and Technology2010，20，3： | 6 |
| 4 | An Efficient ECDSA-Based Signature Scheme for Wireless Networks显示文摘Wired equivalent security is difficult to provide in wireless networks due to high dynamics, wireless link vulnerability, and decentralization. The Elliptic Curve Digital Signature Algorithm(ECDSA) has been applied to wireless networks because of its low computational cost and short key size, which reduces the overheads in a wireless environment. This study improves the ECDSA scheme by reducing its time complexity. The significant advantage of the algorithm is that our new scheme needs not to calculate modular inverse operation in the phases of signature generation and signature verification. Such an improvement makes the proposed scheme more efficient and secure. | XU Zhong DAI Guanzhong YANG Deming | 2006 | Wuhan University Journal of Natural Sciences2006，11，6： | 4 |
| 5 | Evaluation of dolomite reservoirs in the Longwangmiao Formation,Lower Cambrian in Northern Sichuan basin,China显示文摘With the extended petroleum exploration of the carbonate reservoir in the Longwangmiao Formation,Lower Cambrian in Sichuan basin,looking for a new favorable exploration area is the primary task in current exploration.This paper focusing on the dolomite reservoir in the Longwangmiao Formation in the Northern Sichuan basin,will evaluate the reservoir conditions,including reservoir lithology,reservoir spaces,physical properties and other basic characteristics.Combined with sedimentary environment study and diagenesis analysis,the genetic mechanism of Longwangmiao reservoir in study area will be discussed.It indicates that the reservoir rocks of Longwangmiao Formation in the study area are composed of dolarenite and crystalline dolomite,and the main reservoir spaces are intergranular dissolved pores,intragranular dissolved pores and intercrystalline dissolved pores.However,most of dissolved pores have been filled with bitumen,which lead to the reservoir properties very poor,both the porosity and permeability are worse than that of central Sichuan basin,so the reservoir in the Longwangmiao Formation in the Northern Sichuan basin is low-porosity and low-permeability reservoir.During the Early Cambrian Longwangmiao period,the study was near the old-land,and the energy of sea water was not enough to deposit many grain shoals,which cause the sediments are small with lots of quartz and muds.Moreover,because lacking of large scale karstification in the late diagenesis,there isn't much dissolved pores and vugs develop in the Longwangmiao Formation.Some Intergranular dissolved pores and intercrystalline dissolved pores formed by the early atmosphere water dissolved exist as some reservoir spaces,but most of them have been filled with bitumen,which was residual when the ancient oil reservoir transformed.Above factors cause the Longwangmiao Formation in the Northern Sichuan basin become not a very favorable reservoir in Sichuan basin. | Xuefei Yang Yaping Wang Xingzhi Wang Deming Zeng Longbo Xu Zisang Huang | 2017 | Petroleum2017，3，4： | 3 |
| 6 | Recent advances in interlayer and separator engineering for lithium-sulfur batteries显示文摘Lithium-sulfur(Li-S)batteries have great potential in next-generation energy storage due to its high theoretical specific capacity and energy density.However,there are several challenges to the practical application of Li-S batteries including the growth of lithium dendrites and the shuttle effect of polysulfide.Introducing interlayeres(freestanding or coated on the separator)is an effective approach to reduce these obstacles and improve the electrochemical performance of Li-S batteries.In this review,we briefly summarize the interlayer materials and structures modified on both cathodic and anodic sides including(ⅰ)carbon-based materials,(ⅱ)polymers,(ⅲ)inorganic metal compounds,(iv)metal-organic frameworks,as well as(v)the novel separators in recent years.We also systematically address the fabrication processes,assembling methods,and functions of interlayers for enhancing the performance of Li-S batteries.Furthermore,the prospects and outlooks of the future development of advanced interlayers and separators are also presented. | Deming Zhu Tao Long Bin Xu Yixin Zhao Haitao Hong Ruijie Liu Fancheng Meng Jiehua Liu | 2021 | Journal of Energy Chemistry2021，30，6： | 2 |
| 7 | Spatial structure and species composition of soil seed banks in moving sand dune systems of northeast China显示文摘Soil seed banks can provide a mechanistic for understanding the recruitment dynamics and can inform conservation management of ecosystems. To investigate the contribution of soil seed banks to vegetation restoration in moving sand dune systems, we compared seed structure and species similarity between soil seed banks and standing vegetation among moving sand dunes, ecotones and dune slacks in northeast China. Average seed density in dune slacks was greater than in ecotones or moving sand dunes.Seed density in the soil layer of 0–10 cm was greater than at 10–20 cm both in the moving sand dunes and the ecotones, but seed densities were similar at depths of 10–20and 20–30 cm in moving sand dunes. Moreover, the spatial autocorrelation of seed density on moving sand dunes was weak but was strong on the ecotones and dune slacks. The species in the soil seed bank of moving sand dune systems were nearly all annuals, and the low similarity was mainly due to the lack of perennial species that were common in standing vegetation. Consequently, vegetation restoration cannot mainly rely on the soil seed banks in the movingsand dunes and more attention should be paid to protection of the dune slacks because they are the main source of seed disperse and seedling recruitment in moving sand dune systems. | Chunping Miao Xuehua Li Meiyu Jia Xu Han Deming Jiang | 2016 | Journal of Forestry Research2016，27，1： | 2 |

| 14 | Nest-type NCM ■ Pt/C with oxygen capture character as advanced electrocatalyst for oxygen reduction reaction显示文摘A unique nest-type catalyst has been designed with a nest of oxygen capture surrounding catalytic Pt centers, which shows much promoted performance, on the base of Pt/C catalyst, for oxygen reduction reaction(ORR). The nest is constructed with nitrogen-doped carbon matrix(NCM), derived from the controlled carbonization of PANI precursor, to cover Pt/C catalyst. The unique structure of the catalyst(denoted as NCM■ Pt/C) has many merits. Firstly, it can capture oxygen both in air and in acidic electrolyte. Compared with naked Pt/C, it is found that, in air, the oxygen concentration within the porous nest of NCM surrounding Pt/C particles is ~13 times higher than atmospheric oxygen concentration and, in acidic electrolyte, the concentration of activated oxygen over the catalyst NCM■ Pt/C rise to~1.9 times. Secondly, the NCM nest offers a special electronic modulation on Pt centers toward modified ORR kinetics and then catalytic performances. With these merits, compared with Pt/C, the NCM■ Pt/C catalyst shows 3.2 times higher turnover frequency value and 2.9 times enhanced specific activity for ORR with half-wave potential at 0.894 V. After 50,000 sweeping cycles, the NCM■ Pt/C catalyst retains~66% mass activity and still has advantages over the fresh Pt/C catalyst. We envision that the nest-type catalyst provides a new idea for progress of practical Pt/C ORR catalyst. | Teng Chen Yida Xu Deming Meng Xuefeng Guo Yan Zhu Luming Peng Jianqiang Hu Weiping Ding | 2022 | Journal of Energy Chemistry2022，31，8： | 1 |

| 16 | Powerful supercontinuum vortices generated by femtosecond vortex beams with thin plates显示文摘We demonstrate numerically and experimentally the generation of powerful supercontinuum vortices from femtosecond vortex beams by using multiple thin fused silica plates.The supercontinuum vortices are shown to preserve the vortex phase profile of the initial beam for spectral components ranging from 500 nm to 1200 nm.The transfer of the vortex phase profile results from the inhibition of multiple filamentation and the preservation of the vortex ring with relatively uniform intensity distribution by means of the thin-plate scheme,where the supercontinuum is mainly generated from the self-phase modulation and self-steepening effects.Our scheme works for vortex beams with different topological charges,which provides a simple and effective method to generate supercontinuum vortices with high power. | Litong Xu Dongwei Li Junwei Chang Deming Li Tingting Xi Zuoqiang Hao | 2022 | Photonics Research2022，10，3： | 1 |
| 17 | Cost Sharing Based Truthful Spectrum Auction with Collusion-Proof显示文摘Spectrum auction is an important approach of spectrum distribution in cognitive radio networks. However, a single secondary user(SU) probably can't afford the price of spectrum. Multiple SUs grouping together to participate in the auction as a whole is helpful to increase purchasing power. However, SUs could suffer from a new group cheating problem, i.e., parts of users conspire to manipulate the auction by submitting untruthful bids. Existing auction mechanisms were mainly designed to be strategy-proof only for individual user and can't deal with group cheating. In this paper, a novel spectrum auction mechanism called COSTAG(COst Sharing based Truthful Auction with Group-buying) is proposed to address the group cheating problem. COSTAG consists of a grouping rule to perform grouping and a payment rule to determine the market-clearing price in the spectrum auction. Different from single-echelon pricing approach employed in existing works, a multi-echelon pricing strategy is designed to increase the transaction rate and optimize social profit for the auction. Comprehensive theoretical analysis shows that COSTAG can satisfy the crucial economic robustness properties, both individual and group truthfulness. Simulations demonstrate that comparing with existing works, COSTAG can improve the system performance significantly. | Deming Pang Zhigang Deng Gang Hu Yingwen Chen Ming Xu | 2018 | China Communications2018，15，2： | 1 |
