| 1 | Rates of litter decomposition in terrestrial ecosystems:global patterns and controlling factors显示文摘Aims We aim to construct a comprehensive global database of litter decomposition rate(k value)estimated by surface floor litterbags,and investigate the direct and indirect effects of impact factors such as geographic factors(latitude and altitude),climatic factors(mean annual tempePlrature,MAT;mean annual precipitation,MAP)and litter quality factors(the contents of N,P,K,Ca,Mg and C:N ratio,lignin:N ratio)on litter decomposition.Methods We compiled a large data set of litter decomposition rates(k values)from 110 research sites and conducted simple,multiple regression and path analyses to explore the relationship between the k values and impact factors at the global scale.Important findings The k values tended to decrease with latitude(LAT)and lignin content(LIGN)of litter but increased with temperature,precipitation and nutrient concentrations at the large spatial scale.Single factor such as climate,litter quality and geographic variable could not explain litter decomposition rates well.However,the combination of total nutrient(TN)elements and C:N accounted for 70.2%of the variation in the litter decomposition rates.The combination of LAT,MAT,C:N and TN accounted for 87.54%of the variation in the litter decomposition rates.These results indicate that litter quality is the most important direct regulator of litter decomposition at the global scale.This data synthesis revealed significant relationships between litter decomposition rates and the combination of climatic factor(MAT)and litter quality(C:N,TN).The global-scale empirical relationships developed here are useful for a better understanding and modeling of the effects of litter quality and climatic factors on litter decomposition rates. | Deqiang Zhang Dafeng Hui Yiqi Luo Guoyi Zhou | 2008 | Journal of Plant Ecology2008，1，2： | 99 |
| 2 | Climate and litter C/N ratio constrain soil organic carbon accumulation显示文摘Soil organic carbon(SOC) plays critical roles in stabilizing atmospheric CO2 concentration, but the mechanistic controls on the amount and distribution of SOC on global scales are not well understood. In turn, this has hampered the ability to model global C budgets and to find measures to mitigate climate change. Here, based on the data from a large field survey campaign with 2600 plots across China’s forest ecosystems and a global collection of published data from forested land, we find that a low litter carbon-to-nitrogen ratio(C/N) and high wetness index(P/PET, precipitation-to-potentialevapotranspiration ratio) are the two factors that promote SOC accumulation, with only minor contributions of litter quantity and soil texture. The field survey data demonstrated that high plant diversity decreased litter C/N and thus indirectly promoted SOC accumulation by increasing the litter quality. We conclude that any changes in plant-community composition, plant-species richness and environmental factors that can reduce the litter C/N ratio, or climatic changes that increase wetness index, may promote SOC accumulation. The study provides a guideline for modeling the carbon cycle of various ecosystem scales and formulates the principle for land-based actions for mitigating the rising atmospheric CO2 concentration. | Guoyi Zhou Shan Xu Philippe Ciais Stefano Manzoni Jingyun Fang Guirui Yu Xuli Tang Ping Zhou Wantong Wang Junhua Yan Gengxu Wang Keping Ma Shenggong Li Sheng Du Shijie Han Youxin Ma Deqiang Zhang Juxiu Liu Shizhong Liu Guowei Chu Qianmei Zhang Yuelin Li Wenjuan Huang Hai Ren Xiankai Lu Xiuzhi Chen | 2019 | National Science Review2019，6，4： | 21 |
| 3 | In vitro culture and differentiation of rat embryonic midbrain-derived neural stem cells显示文摘BACKGROUND:Midbrain-derived neural stem cells (mNSCs) can differentiate into functional mature dopaminergic neurons. The mNSCs are considered the ideal choice for cell therapy of Parkinson’s disease. OBJECTIVE: To isolate rat embryonic mNSCs and to observe the differentiation characteristics of mNSCs induced by cell growth-promoting factors. DESIGN,TIME AND SETTING: An in vitro cell culture study based on the molecular biology of nerve cells was carried out at the Institute of Clinical Medicine,China-Japan Friendship Hospital (China) from March to November 2007. MATERIALS: Sprague Dawley rats at embryonic day 14 were used in this study. Nestin antibody,β-Ⅲ tubulin antibody,glial fibrillary acidic protein (GFAP) antibody and cyclic nucleotide 3’-phosphohydrolase (CNPase) antibody were provided by Abcam; DMEM/F12 medium and N2 supplement were provided by In-vitrogen; epidermal growth factor (EGF) and fibroblast growth factor-2 (FGF2) were provided by R&D Sys-tems. METHODS: The ventral mesencephalon was dissected from embryonic day 14 rat embryos. By trypsin di-gestion and mechanical separation,the brain tissue was triturated into a fine single-cell suspension. The cells were cultured in 5 mL serum-free medium containing DMEM/F12,1% N2 supplement,20 ng/mL EGF and FGF2. The mNSCs at the third generation were coated with 10 μg/mL polylysine and induced to differenti-ate in the DMEM/F12 supplemented with 1% fetal bovine serum and 1% N2. MAIN OUTCOME MEASURES: The neural spheres of the third passage were identified by nestin im-munofluorescence; at the same time,the cells were induced to differentiate,and the types of differentiated cell were identified by immunofluorescence for βⅢ tubulin,GFAP and CNPase. RESULTS: Seven days after primary culture,a great many neurospheres could be obtained by successive pasage. Immunofluorescence assays showed that the neurospheres were nestin positive,and after differentia-tion,the cells expressed GFAP,CNPase and β-Ⅲ-tubulin. CONCLUSION: Embryonic day 14 rat mNSCs can differentiate into neuron-like cells and glial cells fol-lowing induction by EGF,FGF2 and N2 additive. | Xingli Deng Ruen Liu Zhongtang Feng Jing Guo Wu Wang Deqiang Lei Hongyan Li Zhihua Chen | 2008 | Neural Regeneration Research2008，3，11： | 19 |
| 4 | Effect of N and P addition on soil organic C potential mineralization in forest soils in South China显示文摘Atmospheric nitrogen deposition is at a high level in some forests of South China. The effects of addition of exogenous N and P on soil organic carbon mineralization were studied to address: (1) if the atmospheric N deposition promotes soil C storage through decreasing mineralization; (2) if the soil available P is a limitation to organic carbon mineralization. Soils (0-10 cm) was sampled from monsoon evergreen broad-leaved forest (MEBF), coniferous and broad-leaved mixed forest (CBMF), and Pinus massoniana forest (PMF) in Dinghushan Biosphere Reserve (located in Guangdong Province, China). The soils were incubated at 25°C for 45 weeks, with addition of N (NH4NO3 solution) or P (KH2PO4 solution). CO2-C emission and the inorganic N (NH4+-N and NO3?-N) of the soils were determined during the incubation. The results showed that CO2-C emission decreased with the N addition. The addition of P led to a short-term sharp increase in CO2 emission after P application, and the responses of CO2-C evolution to P addition in the later period of incubation related to forest types. Strong P inhibition to CO2 emission occurred in both PMF and CBMF soils in the later incubation. The two-pool kinetic model was fitted well to the data for C turnover in this experiment. The model analysis demonstrated that the addition of N and P changed the distribution of soil organic C between the labile and recalcitrant pool, as well as their mineralization rates. In our experiment, soil pH can not completely explain the negative effect of N addition on CO2-C emission. The changes of soil inorganic N during incubation seemed to support the hypothesis that the polymerization of added nitrogen with soil organic compound by abiotic reactions during incubation made the added nitrogen retard the soil organic carbon mineralization. We conclude that atmospheric N deposition contributes to soil C accretion in the three subtropical forest ecosystems, however, the shortage of soil available P in CBMF and PMF may also retard soil organic C mineralization. | OUYANG, Xuejun ZHOU, Guoyi HUANG, Zhongliang ZHOU, Cunyu LI, Jiong SHI, Junhui ZHANG, Deqiang | 2008 | Journal of Environmental Sciences2008，20，9： | 17 |
| 5 | Measuring Conflict Functions in Generalized Power Space显示文摘One of the most important open issues is that the classical conflict coefficient in D-S evidence theory (DST) cannot correctly determine the conflict degree between two pieces of evidence. This drawback greatly limits the use of DST in real application systems. Early researches mainly focused on the improvement of Dempster’s rule of combination (DRC). However, the current research shows it is very important to define new conflict coefficients to determine the conflict degree between two or more pieces of evidence. The evidential sources of information are considered in this work and the definition of a conflict measure function (CMF) is proposed for selecting some useful CMFs in the next fusion work when sources are available at each instant. Firstly, the definition and theorems of CMF are put forward. Secondly, some typical CMFs are extended and then new CMFs are put forward. Finally, experiments illustrate that the CMF based on Jousselme and its similar ones are the best suited ones. | HU Lifang GUAN Xin DENG Yong HAN Deqiang HE You | 2011 | Chinese Journal of Aeronautics2011，24，1： | 11 |

| 7 | High-voltage Ride Through Strategy for DFIG Considering Converter Blocking of HVDC System显示文摘This paper presents a P-Q coordination based highvoltage ride through(HVRT) control strategy for doubly fed induction generators(DFIGs) based on a combined Q-V control and P-V de-loading control. The active/reactive power injection effect of DFIG on transient overvoltage is firstly analyzed and the reactive power capacity evaluation of DFIG considering its de-loading operation is then conducted. In the proposed strategy, the reactive power limit of DFIG can be flexibly extended during the transient process in coordination with its active power adjustment. As a result, the transient overvoltage caused by DC bipolar block can be effectively suppressed. Moreover, key outer loop parameters such as Q-V control coefficient and deloading coefficient can be determined based on the voltage level of point of common coupling(PCC) and the available power capacity of DFIG. Finally, case studies based on MATLAB/Simulink simulation are used to verify the effectiveness of the proposed control strategy. | Changping Zhou Zhen Wang Ping Ju Deqiang Gan | 2020 | Journal of Modern Power Systems and Clean Energy2020，8，3： | 10 |
| 8 | Differential water use strategies among selected rare and endangered species in West Ordos Desert of China显示文摘Aims West Ordos Desert(WOD)in Inner Mongolia of China is charac-terized by unique geographical and ecological features to avoid the direct invasion of Quaternary Continental Glaciation,so it hosts many endangered relic species such as Tetraena mongol-ica,Ammopiptanthus mongolicus and Potaninia mongolica from Tertiary.However,how these plants utilize available water sources remains unknown.The objective of this study was to investigate the water utilization strategies of selected rare and endangered plant species in WOD by comparing hydrogen isotope ratios between their xylem water and possible water sources following four rainfall events of varying-intensities.Methods We measured the hydrogen isotope ratios of xylem water from T.mongolica,A.mongolicus and P.mongolica and an accom-panying species Sarcozygium xanthoxylum and potential water sources(including precipitation and soil water in different soil layers from 0 to 150 cm)over 9 days following each of four varying-intensity rainfall events during the summer of 2012.And then calculated the percentage utilization of potential water sources by each species after each rainfall events using the linear mixing model.We also made the measurements of soil moisture and root biomass in favor of interpretation of plant water use strategies.Important Findings Tetraena mongolica,A.mongolicus and S.xanthoxylum primarily relied on deep soil water,whereas P.mongolica depended predomi-nantly on rainwater.These rare and endangered desert plants had differential utilizations of available water sources,so some com-petition for limited water existed among some species.Tetraena mongolica had a competitive relationship in absorption of soil moisture with the same family species S.xanthoxylum,suggesting that T.mongolica and S.xanthoxylum should be restored separately at different areas in the WOD.Overall,this study provides a better understanding of water use strategies of these four plants and scien-tific evidence for protecting rare and endangered plants,maintain-ing regional species diversity,and developing effective vegetation restoration plans in the WOD. | Jie Chen Qing Xu Deqiang Gao Aiyun Song Yuguang Hao Yingbin Ma | 2017 | Journal of Plant Ecology2017，10，4： | 9 |

| 10 | NaAlSi_3O_8-hollandite and other high-pressure minerals in the shock melt veins of the Suizhou meteorite显示文摘The Suizhou L6 chondrite contains a few very thin shock melt veins of 0.02-0.09 mm in width. In spite of small width of the veins, shock-induced high-pressure phases, such as coarse-grained NaAlSi3O8-hollandite, ringwoodite, majorite and fine-grained matrix majorite-pyropess have been discovered in these veins. NaAlSi3O8-hollandite, the high-pressure phase of plagioclase, in Suizhou shock veins occurs as a single phase mineral, no silicate glassy phase, such as albitic glass, was incorporated with it. The presence of above-mentioned high-pressure phases constrains the high pressure (up to 23-24 GPa) and high temperature (up to 1900-2000℃) regime in Suizhou shock veins, and indicates that the duration of high-pressure regime in the veins should be long enough (a few seconds) for phase transformation and crystallization of minerals under pressure. The discovery of the first natural single-phase crystalline NaAlSi3O8- holland-ite in Suizhou meteorite is of important significance in understanding the Earth’ | XIE Xiande, CHEN Ming, WANG Deqiang & El Goresy A.1.Guangzhou Institute of Geochemistry, Chinese Academy of Sciences, Guangzhou 510640, China 2.

| 11 | Research on the Crack Detection of Conductive Components Using Pulsed Eddy Current Thermography显示文摘Crack of conductive component is one of the biggest threats to daily production. In order to detect the crack on conductive component,the pulsed eddy current thermography models were built according to different materials with the cracks based on finite element method(FEM) simulation. The influence of the induction heating temperature distribution with the different defect depths were simulated for the carbon fiber reinforced plastic(CFRP) materials and general metal materials. The grey value of image sequence was extracted to analyze its relationship with the depth of crack. Simulative and experimental results show that in the carbon fiber reinforced composite materials,the bigger depth of the crack is,the larger temperature rise of the crack during the heating phase is; and the bigger depth of the crack is,the faster the cooling rate of the crack during the cooling phase is. In general metal materials,the smaller depth of the crack is,the lager temperature rise of the crack during the heating phase is; and the smaller depth of the crack is,the faster the cooling rate of crack during the cooling phase is. | ZHOU Deqiang CHANG Xiang DU Yang CAO Piyu WANG Hua ZHANG Hong | 2017 | Instrumentation2017，4，3： | 8 |
| 12 | New method for measuring the degree of conflict among general basic probability assignments显示文摘There is doubt about Dempster's rule of combination because of counter-intuitive results when dealing with conflict information in intelligent reasoning.Therefore,many modified combination rules have been presented in the literature on multi-source information fusion and reasoning with uncertainty.However,the issue of identifying conflict among evidence has been ignored.A new parameter measuring conflict evidence called the conflict distance parameter is defined to determine whether there are conflicts in evidence based on the analysis of existing conflict parameters.At the same time,a decisive rule,which a reasonable conflict measure function should satisfy,is put forward.Finally,an analysis of two typical counter-intuitive situations is given,showing that the new parameter can not only satisfy the decisive rule,but can also attain the same effect as a two-dimensional measure when deciding whether to use the Dempster's rule of combination,and can exceed its effect when deciding whether to use Dezert-Smarandache theory. | HE You HU LiFang GUAN Xin DENG Yong HAN DeQiang | 2012 | Science China(Information Sciences)2012，55，2： | 7 |
| 13 | Microstructure and domain engineering of lithium niobate crystal films for integrated photonic applications显示文摘Recently,integrated photonics has attracted considerable interest owing to its wide application in optical communication and quantum technologies.Among the numerous photonic materials,lithium niobate film on insulator(LNOI)has become a promising photonic platform owing to its electro-optic and nonlinear optical properties along with ultralow-loss and high-confinement nanophotonic lithium niobate waveguides fabricated by the complementary metal-oxide-semiconductor(CMOS)-compatible microstructure engineering of LNOI.Furthermore,ferroelectric domain engineering in combination with nanophotonic waveguides on LNOI is gradually accelerating the development of integrated nonlinear photonics,which will play an important role in quantum technologies because of its ability to be integrated with the generation,processing,and auxiliary detection of the quantum states of light.Herein,we review the recent progress in CMOS-compatible microstructure engineering and domain engineering of LNOI for integrated lithium niobate photonics involving photonic modulation and nonlinear photonics.We believe that the great progress in integrated photonics on LNOI will lead to a new generation of techniques.Thus,there remains an urgent need for efficient methods for the preparation of LNOI that are suitable for large-scale and low-cost manufacturing of integrated photonic devices and systems. | Dehui Sun Yunwu Zhang Dongzhou Wang Wei Song Xiaoyan Liu Jinbo Pang Deqiang Geng Yuanhua Sang Hong Liu | 2020 | Light(Science & Applications)2020，9，1： | 7 |
| 14 | CO_2 efflux from different forest soils and impact factors in Dinghu Mountain, China显示文摘CO2 fluxes from soils and related environmental factors were measured in three forest ecosystems of Dinghu Mountain using static chamber-gas chromatograph technique for one year. The seasonal pattern of CO2 flux, contribution of litter on total CO2 flux and the correlations of CO2 flux with soil temperature and soil water content were examined for each type of forest. The results were given as followings: (1) The seasonal patterns of CO2 flux from soil of the three types of forest were similar, with a higher CO2 flux in rainy season than in dry season. The comparative relations of mean annual CO2 fluxes between the three sites were expressed as:monsoon forest > mixed forest > pine forest. (2) CO2 fluxes from litter decomposition in monsoon forest, mixed forest and pine forest accounted for 24.43%, 41.75% and 29.23% of the corresponding total CO2 fluxes from forest floor, respectively. (3) Significant relationships were found between CO2 fluxes and soil temperatures at 5 cm depth for the three types of forest, which could be best described by exponential equations. The calculated Q10 values based on soil temperature at 5 cm depth ranged from 1.86 to 3.24. More significant relationships were found between CO2 fluxes and soil water content when the annual variation coefficients of soil moisture were higher. | ZHOU Cunyu, ZHOU Guoyi, ZHANG Deqiang, WANG Yinghong & LIU Shizhong Dinghushan Forest Ecosystem Research Station, Chinese Academy of Sciences, Guangzhou 510650, China Institute of Atmospheric Physics, Chinese Academy of Sciences, Beijing 100029, China | 2005 | Science China Earth Sciences2005，48，z1： | 6 |
| 15 | Highly efficient hybrid warm white organic light-emitting diodes using a blue thermally activated delayed fluorescence emitter: exploiting the external heavy-atom effect显示文摘To attain high efficiencies in hybrid white organic light-emitting diodes(WOLEDs),mutual quenching of the fluorophors and phosphors should be minimized.Efforts have been devoted to reducing the triplet quenching of phosphors;however,the quenching of fluorophors by the external heavy-atom effect(EHA)introduced by the phosphors is often ignored.Here,we observed that conventional fluorophors and fluorophors with thermally activated delayed fluorescence(TADF)behave differently in the presence of EHA perturbers.The efficiencies of the conventional fluorophors suffer greatly from the EHA,whereas the TADF fluorophors exhibit negligible changes,which makes TADF materials ideal fluorophors for hybrid devices.WOLEDs using a blue TADF fluorophor and an orange phosphor achieve a maximum forward viewing external quantum efficiency of 19.6%and a maximum forward viewing power efficiency of 50.2 lm W^(-1),among the best values for hybrid WOLEDs.This report is the first time that the EHA effect has been considered in hybrid WOLEDs and that a general strategy toward highly efficient hybrid WOLEDs with simple structures is proposed. | Dongdong Zhang Lian Duan Yunge Zhang Minghan Cai Deqiang Zhang Yong Qiu | 2015 | Light(Science & Applications)2015，4，1： | 6 |

| 17 | Effect of calycosin on left ventricular ejection fraction and angiogenesis in rat models with myocardial infarction显示文摘OBJECTIVE:To evaluated the effect of calycosin on left ventricular ejection fraction and angiogenesis.METHODS:Adult male Sprague-Dawley rats were randomly assigned into calycosin-treated groups(0.5,1,2,and 4 mg/kg qd),a dimethyl sulfoxide(DMSO),or a sham-operated control group.The myocardial ischaemia(Ml) model was intraperitoneally administered calycosin for 28 days.The survival rates and left ventricular ejection fractions(LVEF)were compared between groups.The expression levels of vascular endothelial growth factor(VEGF)and cluster of differentiation 31(CD31) in ischaemic myocardium were also measured and compared.RESULTS:The construction of MI model resulted in a LVEF reduction of 50% compared with the sham-control.After 28 days,the LVEF value was 10% higher when calycosin(4 mg/kg) was administered compared with the DMSO group.The expression of VEGF and CD31 showed a dose-dependent manner when calycosin was administrated.The calycosin-treated(4 mg/kg) group displayed a twofold increase in VEGF expression at both the mRNA and protein levels compared with the DMSO group.In addition,CD31 expression in the microvascular increased 1.5-fold in the 4 mg/kg calycosin-treated group.CONCLUSION:Calycosin improved left ventricular ejection fraction in the MI rat models,induced VEGF expression in the ischaemic myocardium,increased CD31 expression and promoted angiogenesis. | Gao Junqing Chen Tao Jin Huigen Liu Zongjun Zhao Deqiang | 2015 | Journal of Traditional Chinese Medicine2015，35，2： | 6 |
| 18 | Primary structure of helix C to helix G of a new retinal protein in H.sp.xz515显示文摘The gene fragment encoding the retinal protein from helix C to helix G in a new strain of halobacteria, H.sp.xz515 has been amplified by PCR method. The nucleotide sequence of this fragment has been determined. The deduced amino acid sequence has been compared with halobium br and other two br-like proteins, ar-1 and ar-2. Results show that those amino acid residues in br, essential for proton pumping and binding to retinal, are conserved. The residue M145 in br may be important for isomerization reaction of retinal. | Hui Wang Shuxuan Zhan Qingan Sun Deqiang Xu Wei Zhao Weida Huang Qingguo Li | 2000 | Chinese Science Bulletin2000，45，12： | 5 |

| 20 | A novel approximation of basic probability assignment based on rank-level fusion显示文摘Belief functions theory is an important tool in the field of information fusion. However, when the cardinality of the frame of discernment becomes large, the high computational cost of evidence combination will become the bottleneck of belief functions theory in real applications. The basic probability assignment (BPA) approximations, which can reduce the complexity of the BPAs, are always used to reduce the computational cost of evidence combination. In this paper, both the cardinalities and the mass assignment values of focal elements are used as the criteria of reduction. The two criteria are jointly used by using rank-level fusion. Some experiments and related analyses are provided to illustrate and justify the proposed new BPA approximation approach. | Yang Yi Han Deqiang Han Chongzhao Cao Feng | 2013 | Chinese Journal of Aeronautics2013，26，4： | 4 |
