| 1 | Effects of cadmium stress on seed germination and seedling growth of Elymus dahuricus infected with the Neotyphodium endophyte显示文摘Various cadmium(Cd)concentrations(0,50,100,200 and 300μmol L-1)affected Elymus dahuricus seed germination,seedling growth,antioxidative enzymes activities(AEA),and amounts of malondialdehyde(MDA)and proline present.These influences were determined for separate E.dahuricus cohorts known to be either infected(E+)or non-infected(E?)by a Neo-typhodium endophyte.Under high Cd concentrations(100,200 and 300μmol L-1),E+specimens showed a significantly (P<0.05)higher germination rate and index,as well as higher values for shoot length,root length and dry biomass.However, the germination rate and index,root length and dry weight did not show a significant(P<0.05)difference under the low Cd concentrations(0 and 50μmol L-1 ).AEA and proline content increased,as did MDA content,in the E+(vs.E-)specimens under high Cd concentrations.There was no significant(P>0.05)difference under low Cd concentrations.Endophyte infection was concluded to be of benefit to E.dahuricus exposed to high Cd concentrations. | ZHANG XingXu LI ChunJie NAN ZhiBiao | 2012 | Science China(Life Sciences)2012，55，9： | 25 |
| 2 | Effects of cutting frequency and height on alkaloid production in endophyte-infected drunken horse grass (Achnatherum inebrians)显示文摘An evaluation was performed on the influence of mowing height (2.5,5.0 or 7.5 cm) and mowing frequency (weekly or fortnightly) on levels of ergot alkaloids (ergine and ergonovine) formed in drunken horse grass,Achnatherum inebrians,grown under greenhouse conditions.Samples were taken monthly and alkaloids were extracted and analyzed by reverse-phase HPLC.Alkaloid levels increased more or less linearly with plant age over the first four months following establishment.Levels were higher in samples cut fortnightly compared to those cut weekly,and were higher when plants were cut at a mowing height of 7.5 cm vs.2.5 cm.In most cases,the highest alkaloid levels observed were almost three times those of the lowest.If plant protection applications are developed for the endophytic fungus,Neotyphodium gansuense,it will be necessary to be aware of the potential role of plant husbandry practices (e.g.,defoliation frequency and intensity) for reducing or enhancing levels of plant alkaloids.Similar husbandry factors may affect alkaloid levels in other Neotyphodium-grass associations,which would be interesting for further study. | ZHANG XingXu LI ChunJie NAN ZhiBiao | 2011 | Science China(Life Sciences)2011，54，6： | 13 |
| 3 | Seasonal dynamics of suprapermafrost groundwater and its response to the freeing-thawing processes of soil in the permafrost region of Qinghai-Tibet Plateau显示文摘The suprapermafrost groundwater in permafrost region not only is an important component of the water cycle and land surface process, but also is closely associated with the charges of ecological environment in cold region. However, the seasonal dynamics, driving factors, and mechanism of suprapermafrost groundwater are not well understood. Based on observation at slope scale on suprapermafrost groundwater dynamics of typical alpine meadows in the Qinghai-Tibet Plateau, the seasonal dynamics, spatial distribution and driving factors of suprapermafrost groundwater were analyzed. The results showed that there were close relationships between the seasonal dynamics of suprapermafrost groundwater and the freezing-thawing processes of active soil in permafrost region. The seasonal dynamics of suprapermafrost groundwater and its slope distribution pattern were controlled by soil temperature of active layers. The phase and range of the suprapermafrost groundwater dynamics are determined by deep soil(below 60 cm depth) moisture and groundwater recharging sources. The relationship between active soil temperatures and dynamics of suprapermafrost groundwater levels was better described by Boltzmann functions. However, the influencing thresholds of soil temperature on groundwater dynamics varied at different depths of active layers and in different slope positions, which resulted in the significant spatial heterogeneity of suprapermafrost groundwater dynamics in slope scale. Land cover change and global warming certainly altered the dynamics of suprapermafrost groundwater and the hydraulic interaction between groundwater and rivers, and consequently altered the overall hydrologic cycle of watershed scale. | CHANG Juan WANG GenXu LI ChunJie MAO TianXu | 2015 | Science China Earth Sciences2015，58，5： | 12 |
| 4 | Carbon pools and fluxes in the China Seas and adjacent oceans显示文摘The China Seas include the South China Sea, East China Sea, Yellow Sea, and Bohai Sea. Located off the Northwestern Pacific margin, covering 4700000 km^2 from tropical to northern temperate zones, and including a variety of continental margins/basins and depths, the China Seas provide typical cases for carbon budget studies. The South China Sea being a deep basin and part of the Western Pacific Warm Pool is characterized by oceanic features; the East China Sea with a wide continental shelf, enormous terrestrial discharges and open margins to the West Pacific, is featured by strong cross-shelf materials transport; the Yellow Sea is featured by the confluence of cold and warm waters; and the Bohai Sea is a shallow semiclosed gulf with strong impacts of human activities. Three large rivers, the Yangtze River, Yellow River, and Pearl River, flow into the East China Sea, the Bohai Sea, and the South China Sea, respectively. The Kuroshio Current at the outer margin of the Chinese continental shelf is one of the two major western boundary currents of the world oceans and its strength and position directly affect the regional climate of China. These characteristics make the China Seas a typical case of marginal seas to study carbon storage and fluxes. This paper systematically analyzes the literature data on the carbon pools and fluxes of the Bohai Sea,Yellow Sea, East China Sea, and South China Sea, including different interfaces(land-sea, sea-air, sediment-water, and marginal sea-open ocean) and different ecosystems(mangroves, wetland, seagrass beds, macroalgae mariculture, coral reefs, euphotic zones, and water column). Among the four seas, the Bohai Sea and South China Sea are acting as CO_2 sources, releasing about0.22 and 13.86–33.60 Tg C yr^(-1) into the atmosphere, respectively, whereas the Yellow Sea and East China Sea are acting as carbon sinks, absorbing about 1.15 and 6.92–23.30 Tg C yr^(-1) of atmospheric CO_2, respectively. Overall, if only the CO_2 exchange at the sea-air interface is considered, the Chinese marginal seas appear to be a source of atmospheric CO_2, with a net release of 6.01–9.33 Tg C yr^(-1), mainly from the inputs of rivers and adjacent oceans. The riverine dissolved inorganic carbon (DIC) input into the Bohai Sea and Yellow Sea, East China Sea, and South China Sea are 5.04, 14.60, and 40.14 Tg C yr^(-1),respectively. The DIC input from adjacent oceans is as high as 144.81 Tg C yr^(-1), significantly exceeding the carbon released from the seas to the atmosphere. In terms of output, the depositional fluxes of organic carbon in the Bohai Sea, Yellow Sea, East China Sea, and South China Sea are 2.00, 3.60, 7.40, and 5.92 Tg C yr^(-1), respectively. The fluxes of organic carbon from the East China Sea and South China Sea to the adjacent oceans are 15.25–36.70 and 43.93 Tg C yr^(-1), respectively. The annual carbon storage of mangroves, wetlands, and seagrass in Chinese coastal waters is 0.36–1.75 Tg C yr^(-1), with a dissolved organic carbon(DOC) output from seagrass beds of up to 0.59 Tg C yr^(-1). Removable organic carbon flux by Chinese macroalgae mariculture account for 0.68 Tg C yr^(-1) and the associated POC depositional and DOC releasing fluxes are 0.14 and 0.82 Tg C yr^(-1), respectively. Thus, in total, the annual output of organic carbon, which is mainly DOC, in the China Seas is 81.72–104.56 Tg C yr^(-1). The DOC efflux from the East China Sea to the adjacent oceans is 15.00–35.00 Tg C yr^(-1). The DOC efflux from the South China Sea is 31.39 Tg C yr^(-1). Although the marginal China Seas seem to be a source of atmospheric CO_2 based on the CO_2 flux at the sea-air interface, the combined effects of the riverine input in the area, oceanic input, depositional export,and microbial carbon pump(DOC conversion and output) indicate that the China Seas represent an important carbon storage area. | Nianzhi JIAO Yantao LIANG Yongyu ZHANG Jihua LIU Yao ZHANG Rui ZHANG Meixun ZHAO Minhan DAI Weidong ZHAI Kunshan GAO Jinming SONG Dongliang YUAN Chao LI Guanghui LIN Xiaoping HUANG Hongqiang YAN Limin HU Zenghu ZHANG Long WANG Chunjie CAO Yawei LUO Tingwei LUO Nannan WANG Hongyue DANG Dongxiao WANG Si ZHANG | 2018 | Science China Earth Sciences2018，61，11： | 12 |

| 6 | Construction of an integrated map and location of a bruchid resistance gene in mung bean显示文摘Bruchid beetle(Callosobruchus chinensis) poses a serious threat to the production and storage of mung bean(Vigna radiata). Mapping bruchid resistance(Br) will provide an important basis for cloning the responsible gene(s) and elucidating its functional mechanism, and will also facilitate marker-assisted selection in mung bean breeding. Here, we report the construction of the genetic linkage groups of mung bean and mapping of the Br1 locus using an RIL population derived from a cross between Berken, a bruchid-susceptible line, and ACC41, a bruchid-resistant line. A total of 560 markers were mapped onto 11 linkage groups,with 38.0% of the markers showing distorted segregation. The lengths of the linkage groups ranged from 45.2 to 117.0 c M with a total coverage of 732.9 c M and an average interval of1.3 c M between loci. Br1 was located on LG9 between BM202(0.7 c M) and Vr2-627(1.7 c M).Based on 270 shared SSR markers, most of the linkage groups were assigned to specific chromosomes. These results should further accelerate the genetic study of this crop. | Lixia Wang Chuanshu Wu Min Zhong Dan Zhao Li Mei Honglin Chen Suhua Wang Chunji Liu Xuzhen Cheng | 2016 | The Crop Journal2016，4，5： | 9 |

| 9 | A new sorbent that simultaneously sequesters multiple classes ofpollutants from water: Surfactant modified zeolite显示文摘A zeolite (ZFA) was synthesized from coal fly ash and then modified using hexadecyltrimethylammonium. The surfactant modified ZFA (SMZFA) was evaluated for its versatility to sequester multiple classes of pollutants from water. The target pollutants include ionic inorganic pollutants (ammonium and phosphate), ionic organic pollutants (methylene blue and humic acid), ionizable organic pollutants (bisphenol A,-chlorophenol and phenol, with different pKa), and electrically neutral or-ganic pollutants (aniline, nitrobenzene, and naphthalene, with different hydrophobicity). The SMZFA showed high potential for the retention of ammonium and phosphate, being comparable with ZFA. While the negative charge in the internal pores of zeolite was responsible for the retention of ammonium, the oxides of CaO, Al2O3and Fe2O3in the non-zeolite fraction, which originated from coal fly ash but received modification during zeolite synthesis, accounted for the removal of phosphate. Results also showed that while ZFA had little affinity for humic acid, the ionizable, and the electrically neutral organic compounds, SMZFA exhibited greatly enhanced adsorption capacity. Thus, the surfactant modified external surface, which formed a bilayer micelle of zeolite, imparts a hydrophobic characteristic that enables the uptake of the organic pollutants. We showed that SMZFA is a promising versatile sorbent for water treatment. | XIE Qiang XIE Jie CHI LiNa LI ChunJie WU DeYi ZHANG ZhenJia KONG HaiNan | 2013 | Science China(Technological Sciences)2013，56，7： | 5 |
| 10 | Hydrodynamic Links between Shallow and Deep Mineralization Systems and Implications for Deep Mineral Exploration显示文摘Deep mineral exploration is increasingly important for finding new mineral resources but there are many uncertainties.Understanding the factors controlling the localization of mineralization at depth can reduce the risk in deep mineral exploration.One of the relatively poorly constrained but important factors is the hydrodynamics of mineralization.This paper reviews the principles of hydrodynamics of mineralization,especially the nature of relationships between mineralization and structures,and their applications to various types of mineralization systems in the context of hydrodynamic linkage between shallow and deep parts of the systems.Three categories of mineralization systems were examined,i.e.,magmatic-hydrothermal systems,structurally controlled hydrothermal systems with uncertain fluid sources,and hydrothermal systems associated with sedimentary basins.The implications for deep mineral exploration,including potentials for new mineral resources at depth,favorable locations for mineralization,as well as uncertainties,are discussed. | CHI Guoxiang XU Deru XUE Chunji LI Zenghua Patrick LEDRU DENG Teng WANG Yumeng SONG Hao | 2022 | Acta Geologica Sinica(English Edition)2022，96，1： | 5 |
| 11 | Effect of Substrate Type on Deposition Behavior and Wear Performance of Ni-Coated Graphite/Al Composite Coatings Deposited by Cold Spraying显示文摘This work focused on the deposition characteristics and wear behavior of Ni-coated graphite mixed with40 vol.% Al(Ni-Gr/Al) composite coatings sprayed on an Al alloy and a steel substrate by cold spraying(CS). The morphology of the ?attened Ni-Gr particles was examined by single-impact tests. Crosssectional microstructure and wear performance of the Ni-Gr/Al composite coatings were studied. Results showed that a larger number of Ni-Gr particles were ?nally bonded with the steel substrate, whereas many craters existed on the Al alloy substrate after the single-impact tests. The coating on the steel substrate had a high thickness, high graphite content and low coe?cient of friction(COF) compared to those on the Al alloy substrate. In addition, the CS coatings presented a homogeneous distribution and uniform morphology of graphite, and a comparative COF to that of conventional thermal sprayed coatings. It was shown that CS could avoid the decomposition and transformation of graphite phase. | Chunjie Huang Wenya Li Yingchun Xie Marie-Pierre Planche Hanlin Liao Ghislain Montavon | 2017 | Journal of Materials Science & Technology2017，33，4： | 4 |
| 12 | Multi-functional polyethersulfone nanofibrous membranes with ultra-high adsorption capacity and ultra-fast removal rates for dyes and bacteria显示文摘The adsorption technology has been widely applied in water remediation for contamination removal of dyes and bacteria,by virtue of the advantages of adsorption technology including high efficiency,energy conservation and ease of operation.Simultaneous removal of dyes and bacteria has been realized by some reported materials,but to achieve satisfactory adsorption amounts and rates remain an unmet goal for decades.Herein,a poly(methacrylatoethyl trimethyl ammonium chloride-co-methyl methacrylate)copolymer was synthesized,and then blended with polyethersulfone for the fabrication of nanofibrous membranes via electrospinning for the use of fast and massive removal of dyes and bacteria.Owing to the introduction of abundant quaternary ammonium groups,the maximum adsorption amount for methyl orange was up to 909.8 mg g^(-1).In addition,the modified nanofibrous membranes showed good recyclability,broad applications in severe environments,selective adsorption ability,and excellent dynamic removal performance.Especially,thanks to the abundant functional groups,the membranes showed fast adsorption ability for bacteria through electrostatic interaction.It should be noted that the clearance ratio for Staphylococcus aureus or Escherichia coli by 6 min of static adsorption could reach 93%or 90%for each.Additionally,dynamic removal ratio via filtration with the nanofibrous membranes could reach 99.7%for Staphylococcus aureus or 98.7%for Escherichia coli in 90 s.Therefore,the proposed approach towards the quaternary ammonium modified polyethersulfone nanofibrous membranes creates a new route for ultra-high adsorption capacity and ultra-fast removal rates for dyes and bacteria in water remediation. | Jianxu Bao Hang Li Yuanting Xu Shengqiu Chen Zhoujun Wang Chunji Jiang Huilin Li Zhiwei Wei Shudong Sun Weifeng Zhao Changsheng Zhao | 2021 | Journal of Materials Science & Technology2021，，19： | 4 |
| 13 | Efficacy of Zhonglun'a-decoction-containing serum on fibroblastlike synoviocyte apoptosis in rats with collagen-induced arthritis via inhibiting Janus kinase/signal transducer and activator of transcription signaling pathway显示文摘OBJECTIVE: To investigate the efficacy of Zhonglun'a-decoction-containing serum(ZHONGL-CS)on the in vitro apoptosis of fibroblast-like synoviocytes(FLS) from rats with collagen-induced arthritis(CIA) by investigating the Janus kinase/signal transducer and activator of transcription(JAK/STAT) signaling pathway.METHODS: A CIA rat model was established using bovine type Ⅱ collagen. FLS were isolated, cultured and identified. A cell counting kit-8 was used to detect cell activity. The half maximal inhibitory concentration(IC50) was calculated. Experimental subjects were divided into control, CIA,ZHONGL-CS, JAK2 inhibitor AG490, and ZHONGLCS with AG490 groups. The in vitro cell cycle and apoptosis rate were detected in FLS by flow cytometry. Bcl-2-associated X protein(Bax), B-cell lymphoma 2(Bcl-2), caspase-3, cyclin D1, phosphorylated JAK2, STAT1, and STAT3 protein expressions in FLS were examined by Western blotting. JAK2, STAT1 and STAT3 mRNA levels were examined by quantitative real-time polymerase chain reaction.RESULTS: Compared with the CIA group, FLS proliferation was inhibited, the FLS G0/G1 cell cycle was arrested, and the rate of FLS apoptosis was increased in the ZHONGL-CS group. In the ZHONGLCS group, the protein levels of Bcl-2 and cyclin D1 were reduced compared with the CIA group and the levels of Bax and caspase-3 in FLS were increased. In the ZHONGL-CS group, the expressions of JAK2, STAT1, and STAT3 mRNA and the levels of phosphorylated JAK2, STAT1, and STAT3 proteins were reduced.CONCLUSION: ZHONGL-CS may induce FLS apoptosis in CIA rats. Activation of the JAK/STAT signaling pathway was inhibited in FLS in vitro. | Yang Yongsheng Dong Qiumei Ma Chunjie Zhang Yudi Li Yongle Chen Kun Zhang Suo | 2019 | Journal of Traditional Chinese Medicine2019，39，2： | 4 |
| 14 | Assessment of Heavy Metals in Grain Fields with Long-term Treatment of Agrochemicals and Organic Manure in Hailun City of Northeast China显示文摘Heavy metals were evaluated in the soils of grain fields in Hailun City Experimental Research Station--Chinese Academy of Sciences (CAS).

| 15 | Purification of starch and phosphorus wastewater using core-shell magnetic seeds prepared by sulfated roasting显示文摘Core-shell magnetic seeds with certain adsorption capacity that were prepared by sulfated roasting, served as the core of a magnetic separation technology for purification of starch wastewater. XRD and SEM results indicate that magnetite's surface transformed to be porous α-Fe_2O_3 structure. Compared with magnetite particles, the specific surface area was significantly improved to be 8.361 from 2.591 m^2/g, with little decrease in specific susceptibility. Zeta potential, FT-IR and XPS experiments indicate that both phosphate and starch adsorbed on the surface of the core-shell magnetic seeds by chemical adsorption, which fits well with the Langmuir adsorption model. The porous surface structure of magnetic seeds significantly contributes to the adsorption of phosphate and starch species, which can be efficiently removed to be 1.51 mg/L(phosphate) and 9.51 mg/L(starch) using magnetic separation. | Chunjie Du Jinsheng Yu Wei Sun Haisheng Han Yuehua Hu Pan Chen Panpan Hou Runqing Liu Li Wang Yue Yang Ruohua Liu Lei Sun | 2019 | Journal of Environmental Sciences2019，31，7： | 4 |
| 16 | Rh-doped PdAg nanoparticles as efficient methanol tolerance electrocatalytic materials for oxygen reduction显示文摘Direct methanol fuel cells(DMFCs)have received extensive attention on their high efficiency,high reliability,and no carbon emission.Unfortunately,the poor methanol tolerance and sluggish oxygen reduction reaction(ORR)at cathode have seriously hindered their further development.Herein we report the synthesis of a new class of Rh-doped PdAg alloy nanoparticles(NPs)for boosting ORR activity with high methanol tolerance capacity concurrently.The ORR mass activity of typical Rh_4Pd_(40)Ag_(56)NPs is 4.2 times higher than that of commercial Pt catalyst.Moreover,it shows a great methanol tolerance capability by maintaining 92.4%in ORR mass activity in alkaline solution with 0.1 mol L^(à1)methanol,against a big decrease of almost 100%for commercial Pt.Even after 30,000 potential cycles with 1.0 mol L^(à1)methanol,Rh_4Pd_(40)Ag_(56)NPs still retain ORR mass activity of up to 68.3%.DFT calculations reveal that excellent ORR performance with excellent methanol tolerance originates the active d-band-pinning engineering for an efficient site-independent electron-transfer.A generalized d-band mediated fine electron-transfer tuning path has blueprinted for effectively minimizing intrinsic ORR barriers with high current density.The present work highlights the key role of Rh doping in enhancing the ORR activity and methanol tolerance ability of PdAg NPs for future high-performance DMFCs. | Yingjun Sun Bolong Huang Nuoyan Xu Yingjie Li Mingchuan Luo Chunji Li Yingnan Qin Lei Wang Shaojun Guo | 2019 | Science Bulletin2019，64，1： | 4 |
| 17 | The equivalent potential of water molecules for electronic structure of lysine显示文摘In order to get more reliable electronic structures of proteins in aqueous solution, it is necessary to construct a potential of water molecules for protein’s electronic structure calculation. The lysine is a hydrophilic amino acid. It is positively charged (Lys+) in neutral water solution. The first-principles, all-electron, ab initio calcula-tions, based on the density functional theory, have been performed to construct such an equivalent potential of water molecules for lysine (Lys+). The process consists of three parts. First, the electronic structure of the cluster containing Lys+ and water molecules is calculated. By adjusting the positions of water molecules, the geometric structure of the cluster having minimum total energy is determined. Then, based on the structure, the electronic structure of Lys+ with the potential of water molecules is calculated using the self-consistent cluster-embedding (SCCE) method. Finally, the electronic structure of Lys+ with the potential of dipoles is calculated. The dipoles are adjusted so that the electronic structure of Lys+ with the potential of dipoles is close to that of water molecules. Thus the equivalent potential of water molecules for the electronic structure of lysine is obtained. The major effect of water molecules on lysine’s electronic structure is raising the occupied eigenvalues about 0.5032 eV, and broadening energy gap 89%. The effect of water molecules on the electronic structure of lysine can be simulated by dipoles potential. | LI ChunJie ZHENG HaoPing WANG XueMei | 2007 | Science China(Physics,Mechanics & Astronomy)2007，50，1： | 4 |
| 18 | Toxicity and mechanisms of action of titanium dioxide nanoparticles in living organisms显示文摘Titanium dioxide nanoparticles(TiO_2 NPs) are one of the most widely used nanomaterials in the consumer products, agriculture, and energy sectors. Their large demand and widespread applications will inevitably cause damage to organisms and ecosystems. A better understanding of TiO_2 NP toxicity in living organisms may promote risk assessment and safe use practices of these nanomaterials. This review summarizes the toxic effects of TiO_2 NPs on multiple taxa of microorganisms, algae, plants, invertebrates, and vertebrates. The mechanism of TiO_2 NP toxicity to organisms can be outlined in three aspects: The Reactive Oxygen Species(ROS)produced by TiO_2 NPs following the induction of electron–hole pairs; cell wall damage and lipid peroxidation of the cell membrane caused by NP-cell attachment by electrostatic force owing to the large surface area of TiO_2 NPs; and TiO_2 NP attachment to intracellular organelles and biological macromolecules following damage to the cell membranes. | Jing Hou Luyao Wang Chunjie Wang Songlin Zhang Haiqiang Liu Shiguo Li Xiangke Wang | 2019 | Journal of Environmental Sciences2019，31，1： | 4 |
| 19 | Optimization of cold-sprayed AA2024/Al_2O_3 metal matrix composites via friction stir processing: Effect of rotation speeds显示文摘In this study, friction stir processing(FSP) was employed to modify cold-sprayed(CSed) AA2024/Al_2 O_3 metal matrix composites(MMCs). Three different rotation speeds with a constant traverse speed were used for FSP. Microstructural analysis of the FSPed specimens reveals significant Al_2 O_3 particle refinement and improved particle distribution over the as-sprayed deposits. After FSP, a microstructural and mechanical gradient MMC through the thickness direction was obtained. Therefore, a hybrid technique combining these two solid-state processes, i.e. CS and FSP, was proposed to produce functionally gradient deposits. The Guinier-Preston-Bagaryatskii zone was dissolved during FSP, while the amounts at different rotation speeds were approximately the same, which is possibly due to the excellent thermal conductivity of the used Cu substrate. Mechanical property tests confirm that FSP can effectively improve the tensile performance and Vickers hardness of CSed AA2024/Al_2 O_3 MMCs. The properties can be further enhanced with a larger rotation speed with a maximum increase of 25.9% in ultimate tensile strength and27.4% in elongation at 1500 rpm. Friction tests show that FSP decreases the wear resistance of CSed MMCs deposits due to the breakup of Al_2 O_3 particles. The average values and fluctuations of friction coefficients at different rotation speeds vary significantly. | Kang Yang Wenya Li Chunjie Huang Xiawei Yang Yaxin Xu | 2018 | Journal of Materials Science & Technology2018，34，11： | 3 |
