| 1 | Preliminary Scientific Results of Chang'E-1 Lunar Orbiter:Based on Payloads Detection Data in the First Phase显示文摘Chang'E-1 lunar Orbiter was launched by Long March 3A rocket from Xichang Satel-lite Launch Center at 18:05BT(Beijing Time) Oct.24,2007.It is the first step of its ambitious three-stage moon program,a new milestone in the Chinese space exploration history.The primary science objectives of Chang'E-1 lunar orbiter are to obtain three-Dimension(3D) stereo images of the lunar surface,to analyze the distribution and abundance of elements on the surface,to investigate the thickness of lunar soil,evaluate helium-3 resources and other characteristics,and to detect the space environment around the moon.To achieve the above four mission objectives,eight sets of scientific instruments are chosen as the payloads of the lunar orbiter,including a CCD stereo camera(CCD),a Sagnac-based interferometer spectrometer(ⅡM),a Laser Altimeter(LAM),a Microwave Radiometer(MRM),a Gamma-Ray Spectrometer(GRS),an X-ray spectrometer(XRS),a High-Energy Particle Detector(HPD),and two Solar Wind Ion Detectors(SWID).The detected data of the payloads show that all payloads work well.This paper introduces the status of payloads in the first phase and preliminary scientific results. | OUYANG Ziyuan JIANG Jingshan LI Chunlai SUN Huixian ZOU Yongliao LIU Jianzhong LIU Jianjun ZHAO Baochang REN Xin YANG Jianfeng ZHANG Wenxi WANG Jianyu MOU Lingli CHANG Jin ZHANG Liyan WANG Huanyu LI Yongquan ZHANG Xiaohui ZHENG Yongchun WANG Shijin BIAN Wei | 2008 | 空间科学学报2008，28，5： | 24 |
| 2 | Cadmium accumulation and tolerance of two castor cultivars in relation to antioxidant systems显示文摘To investigate the effects of Cd on tolerance and antioxidant activities of castor, two different castor(Ricinus communis L.) cultivars(Zibo No. 5 and Zibo No. 8) were used for a hydroponic experiment(0, 1 and 2 mg/L Cd) and a pot experiment using Cd-contaminated soil(34 mg/kg) with the addition of ethylenedinitrilotetraacetic acid(EDTA). The results indicated that there were significant differences between the two cultivars with respect to Cd uptake in shoots(113–248 mg/kg for Zibo No. 5 and 130–288 mg/kg Zibo No. 8), biomass tolerance indexes(64.9%–74.6% for Zibo No. 5 and 80.1%–90.9% for Zibo No. 8) in the hydroponic experiment and survival rates(0% for Zibo No. 5 and 100% for Zibo No. 8)determined by the addition of EDTA in the pot experiment, suggesting that Zibo No. 8 has higher tolerance than Zibo No. 5. Moreover, the castor cultivars have low bioconcentration factors(4.80% for Zibo No. 5 and 5.43% for Zibo No. 8) and low translocation factors(<1%).Consequently, Zibo No. 8 can participate in Cd phytostabilization in highly Cd-polluted areas. The results indicated that glutathione(GSH) as a non-enzymatic antioxidant, and antioxidant enzymes including superoxide dismutase(SOD), catalase(CAT) and guaiacol peroxidase(GPX), were cultivar- and dose-dependent. The higher tolerance of Zibo No. 8compared with Zibo No. 5 can be attributed to the higher GSH levels in the root and higher GPX activity in the leaf. | Hanzhi Zhang Qingjun Guo Junxing Yang Tongbin Chen Guangxu Zhu Marc Peters Rongfei Wei Liyan Tian Chunyu Wang Deyun Tan Jie Ma Gangming Wang Yingxin Wan | 2014 | Journal of Environmental Sciences2014，26，10： | 15 |
| 3 | Application of Pb isotopic tracing technique to constraining the source of Pb in the West Lake Longjing tea显示文摘This paper dealt with the Pb contents and Pb isotopic composition of the West Lake Longjing tea. The results showed that in the tea leaves, from young leaf →old leaf →tea limb, the Pb contents tend to increase gradu-ally from 1.63 →4.84 →6.07×10-6, wich revealed that the Pb was accumulated gradually in the tea. After cleaned, the Pb contents of tea leaves were significantly reduced. This indicated that the deposits on the surface of tea leaves made a great contributuion to Pb contents. The survey results for soils in the relevant tea gardens showed that soil from the Longjing tea garden has higher Pb contents, with an average level of 49.6×10-6, two times those of common soils (24×10-6) in China. Results of the systematic analysis for tea, tea garden soil and the samples with the relevant background of the Pb isotopic composition displayed that the Pb isotopic ratio of tea is 206Pb/207Pb=1.164±0.005 (2σ). The ratio of 206Pb/207Pb for the soil gradually decreased from residue phase, soil dilute acid extract phase, and then to urban topsoil, i.e., 1.175 →1.171 →1.170. The 208Pb/(206Pb+207Pb) ratios also show a similar variation trend. 206Pb/207Pb ratios in the samples with the relevant background were: vehicle exhaust, 1.124; coal-combustion, 1.156; atmosphere, 1.168; and water, 1.166. Comparative studies have shown that Pb pollution is popular in the environ-mental media (soil, atmosphere, water) in Hangzhou. With the aggravation of Pb pollution, the Pb isotopic composi-tion gradually changed from the natural background (soil residues) to the direction of automobile exhaust. This phe-nomenon could illustrate that the pollution source was the vehicle exhaust, while the coal-combustion contributed little to environmental pollution in Hangzhou. The Pb of the Longjing tea came mostly from soluble phase Pb in the polluted soil. Moreover, secondary pollution was caused by vehicle exhaust. | LU Yuanfa YANG Hongmei MA Liyan CHEN Xiqing WANG Qunying | 2011 | Chinese Journal Of Geochemistry2011，30，4： | 13 |
| 4 | A Spore-Pollen Assemblage from the Damoguaihe Formation in the Tamutsag Basin, Mongolia and Its Geological Implication显示文摘Based on the palynological data from Well Ta-19-36 and Well Ta-19-37 in the Ta'nan Sag, and Well Ta-22-1 and Well Ta-21-1 in the Bayin Gobi Sag, a spore-pollen assemblage from the Damoguaihe Formation is named as Cicatricosisporites minutaestriatus- Aequitriradites spinulosus-Protopinus sp. assemblage in the Tamutsag Basin, Mongolia. The assemblage is characterized by abundant gymnosperm pollen and diverse fern spores, counted 46.35%–65.57% and 34.43%–52.58% in percentage respectively. Among the gymnosperm pollen, Pinuspollenites sp.(2.66%–16.94%), Protopinus sp.(0–11.38%) and Protopicea sp.(0–10.81%) are dominant; and Alisporites sp., Cerebropollenites sp., Podocarpidites sp., and Abietineaepollenites sp. are common. Some important elements, such as Chasmatosporites sp., Callialasporites prominulus, Parvisaccites sp., Parcisporites sp., Jiaohepollis cf. annulatus, J. bellus, J. verus, Polycingulatisporites sp., Schizaeoisporites certus, Classopollis annulatus are seen. Within the fern spores, Osmundacidites wellamanii(0.85%–4.93%), Appendicisporites sp.(0–4.45%), Baculatisporites comaumensis(0.80%–2.87%), Cicatricosisporites sp.(0.51%–2.66%), C. minor(0–2.14%), Foraminisporis asymmetricus(0–2.40%), Aequitriradites sp.(0– 2.19%) and Cyathidites minor(0–2.13%) are dominant; and some specie of Densoisporites, Cooksonites, Impardecispora, Pilosisporites, Schizaeosprites, Fixisporites, Leptolepidites, Trilobosporites, Kuylisporites, Klukisporites, Hsuisporites, Couperisporites, Maculatisporites are seen. The angiosperm pollen are rare in the assemblage, characterized by Clavatipollenites sp.(0–0.80%) and Songipollis sp.(0–0.27%). The geological age of the Damoguaihe Formation is assigned to Hauterivian – Barremian of Early Cretaceous according to the palynological data, due to the fact that there existed a lot of diverse spores of the family Schizaeaceae and prosperous gymnosperm saccat pollen which the corpus and sacci are differentiated completely, and the presence of early angiosperm pollen of Clavatipollenites. However, the zircon U-Pb isotopic dating of the volcanic rocks in the Nantun Formation indicated that the overlying strata of the Nantun Formation, i.e. the Damoguaihe Formation must be younger than 127.0±2.0–137.9±1.5 Ma. This is consistent with the palynological data. Furthermore, the vegetation reconstructed on the palynological data of the Damoguaihe Formation is conifer forest with shrubs and grassland, belonging to the semi-humid or humid middle to south subtropical climate. Moreover, three new species, namely Biretisporites punctatus sp. nov., Chasmatosporites reticulates sp. nov. and Concentrisporites contractus sp. nov. are described here. | WANG Liyan WAN Chuanbiao SUN Yuewu | 2014 | Acta Geologica Sinica(English Edition)2014，88，1： | 12 |
| 5 | RAB31 marks and controls an ESCRT-independent exosome pathway显示文摘Exosomes are generated within the multivesicular endosomes(MVEs)as intraluminal vesicles(ILVs)and secreted during the fusion of MVEs with the cell membrane.The mechanisms of exosome biogenesis remain poorly explored.Here we identify that RAB31 marks and controls an ESCRT-independent exosome pathway.Active RAB31,phosphorylated by epidermal growth factor receptor(EGFR),engages flotillin proteins in lipid raft microdomains to drive EGFR entry into MVEs to form ILVs,which is independent of the ESCRT(endosomal sorting complex required for transport)machinery.Active RAB31 interacts with the SPFH domain and drives ILV formation via the Flotillin domain of flotillin proteins.Meanwhile,RAB31 recruits GTPase-activating protein TBC1D2B to inactivate RAB7,thereby preventing the fusion of MVEs with lysosomes and enabling the secretion of ILVs as exosomes.These findings establish that RAB31 has dual functions in the biogenesis of exosomes:driving ILVs formation and suppressing MVEs degradation,providing an exquisite framework to better understand exosome biogenesis. | Denghui Wei Weixiang Zhan Ying Gao Liyan Huang Run Gong Wen Wang Ruhua Zhang Yuanzhong Wu Song Gao Tiebang Kang | 2021 | Cell Research2021，31，2： | 12 |
| 6 | Estimation of the Effects of Maize Straw Return on Soil Carbon and Nutrients Using Response Surface Methodology显示文摘Straw incorporation is generally considered an effective agricultural management practice that improves nutrient cycling and maintains soil fertility. To study the interactive effects of straw returning factors on soil organic carbon and available nutrients, a17-month(May 6, 2016 to October 6, 2017) experiment was conducted on straw incorporation by using response surface methodology under a three-factor(straw length, amount, and burying depth), five-level quadratic orthogonal rotation experimental design. Weight was assigned to each indicator for soil carbon and nutrients and then a comprehensive indicator was established. Then, a second-order polynomial model of the three straw returning factors was established using response surface methodology. Results indicated that17 months after straw incorporation, straw amount and burying depth had significant effects on the comprehensive indicator of soil carbon and nutrients. Straw length and the interactions of straw amount and burying depth showed no significant effects on the comprehensive indicator of soil carbon and nutrients. It was concluded that 17 months after straw incorporation, the highest value of the comprehensive indicator of soil carbon and nutrients was achieved when the straw length, amount, and burying depth were approximately 17–20 cm, 740–840 g m^(-2), and 9–13 cm, respectively, which can be recommended as the most suitable parameters for use in straw returning in the study area. | ZHOU Dongxing SU Ye NING Yucui RONG Guohua WANG Guangdong LIU Di LIU Liyan | 2018 | Pedosphere2018，28，3： | 12 |
| 7 | Spatial and Temporal Changes of Arable Land Driven by Urbanization and Ecological Restoration in China显示文摘Since the industrial revolution, human activities have both expanded and intensified across the globe resulting in accelerated land use change. Land use change driven by China’s development has put pressure on the limited arable land resources, which has affected grain production. Competing land use interests are a potential threat to food security in China. Therefore, studying arable land use changes is critical for ensuring future food security and maintaining the sustainable development of arable land. Based on data from several major sources, we analyzed the spatio-temporal differences of arable land among different agricultural regions in China from 2000 to 2010 and identified the drivers of arable land expansion and loss. The results revealed that arable land decreased by 5.92 million ha or 3.31%. Arable land increased in the north and decreased in the south of China. Urbanization and ecological restoration programs were the main drivers of arable land loss, while the reclamation of other land cover types(e.g., forest, grassland, and wetland) was the primary source of the increased arable land. The majority of arable land expansion occurred in the Northwest, but the centroid for grain production moved to northeast, which indicated that new arable land was of poor quality and did not significantly contribute to the grain production capacity. When combined with the current ‘Red Line of Arable Land Policy’(RAL) and ‘Ecological Redline Policy’(EPR), this study can provide effective information for arable land policymaking and help guide the sustainable development of arable land. | WANG Liyan ANNA Herzberger ZHANG Liyun XIAO Yi WANG Yaqing XIAO Yang LIU Jianguo OUYANG Zhiyun | 2019 | Chinese Geographical Science2019，29，5： | 9 |

| 9 | Glass-forming ability and crystallization of Mg-Ni amorphous alloys with Y addition显示文摘Mg86.33Ni13.67-xYx(x=0, 1, 3, 6, 10) amorphous alloys were obtained by single-roller melt-spinning technique and the effect of Y addition on the glass forming ability(GFA), crystallization and micro-hardness of Mg-Ni alloys were studied. The results show that the GFA of Mg86.33Ni13.67-xYx(x=0, 1, 3, 6, 10) is improved successfully with the Y addition. The highest GFA appeares at x=6, while the reduced glass transition temperature (Trg) is 0.5225 and the supercooled liquid region(ΔTx) is 42.06 K; the position of the main diffraction halo is different for the alloys, and the maximum of the main diffraction halo of alloys with x=0, 1, 3 corresponds to the main peaks of a metastable fcc-Mg6Ni or fcc-Mg6Ni + Ni-Y intermetallic phases, and for the alloys with x=6, 10, it corresponds to Mg-Y and Ni-Y intermetallic phases; the micro-hardness of the alloys is improved with Y additions, and the highest micro-hardness is obtained at x=6 at.%, which is 960 MPa. | Liu Liyan Teng Xinying Wang Yongjie Liu Teng | 2012 | Rare Metals2012，31，3： | 8 |
| 10 | Analysis of genetic architecture and favorable allele usage of agronomic traits in a large collection of Chinese rice accessions显示文摘Genotyping and phenotyping large natural populations provide opportunities for population genomic analysis and genome-wide association studies(GWAS). Several rice populations have been re-sequenced in the past decade;however, many major Chinese rice cultivars were not included in these studies. Here, we report large-scale genomic and phenotypic datasets for a collection mainly comprised of 1,275 rice accessions of widely planted cultivars and parental hybrid rice lines from China. The population was divided into three indica/Xian and three japonica/Geng phylogenetic subgroups that correlate strongly with their geographic or breeding origins. We acquired a total of 146 phenotypic datasets for 29 agronomic traits under multi-environments for different subpopulations. With GWAS, we identified a total of 143 significant association loci, including three newly identified candidate genes or alleles that control heading date or amylose content. Our genotypic analysis of agronomically important genes in the population revealed that many favorable alleles are underused in elite accessions, suggesting they may be used to provide improvements in future breeding efforts. Our study provides useful resources for rice genetics research and breeding. | Xiuxiu Li Zhuo Chen Guomin Zhang Hongwei Lu Peng Qin Ming Qi Ying Yu Bingke Jiao Xianfeng Zhao Qiang Gao Hao Wang Yunyu Wu Juntao Ma Liyan Zhang Yongli Wang Lingwei Deng Shanguo Yao Zhukuang Cheng Diqiu Yu Lihuang Zhu Yongbiao Xue Chengcai Chu Aihong Li Shigui Li Chengzhi Liang | 2020 | Science China(Life Sciences)2020，63，11： | 8 |

| 18 | COR27 and COR28 encode nighttime repressors integrating Arabidopsis circadian clock and cold response显示文摘It was noted that circadian components function in plant adaptation to diurnal temperature cycles and freezing tolerance.Our genome-wide transcriptome analysis revealed that evening-phased COR27 and COR28 mainly repress the transcription of clockassociated evening genes PRR5,ELF4 and cold-responsive genes.Chromatin immunoprecipitation indicated that CCA1 is recruited to the site containing EE elements of COR27 and COR28 promoters in a temperaturedependent way.Further genetic analysis shows COR28 is essential for the circadian function of PRR9 and PRR7.Together,our results support a role of COR27 and COR28 as nighttime repressors integrating circadian clock and plant cold stress responses. | peng wang xuan cui chunsheng zhao liyan shi guowei zhang fenglong sun xiaofeng cao li yuan qiguang xie xiaodong xu | 2017 | Journal of Integrative Plant Biology2017，59，2： | 6 |
| 19 | Tissue engineering using 3D printed nano-bioactive glass loaded with NELL1 gene for repairing alveolar bone defects显示文摘The purposes of this study were to construct a novel tissue engineered bone composed of 3Dprinted bioactive glass block/chitosan nanoparticles(BD/CSn)composites loaded with Nel-like Type I molecular-1 DNA(pDNA-NELL1)and/or bone marrow mesenchymal stem cells(BMSCs),and study their osteogenic activities by repairing bone defects in rhesus monkeys.CSn with NELL1 gene plasmid and rhesus monkey BMSCs were composited with a BD scaffold to prepare the tissue-engineered bone.Four adult female rhesus monkeys with 10-to 12-years old and 5-7 kg in weight were used in animal experiments.The first and second premolar teeth from four regions of each monkey were removed to form bone defects with size of 10×10×5 mm,which were then implanted with above-mentioned tissue engineered bone.At 12 weeks after the implantation,gross observations,X-ray and micro-CT observations revealed that the new bone was extremely close to normal bone in mass,density,hardness,and structure.The bony cortex was smooth and closely connected to the surrounding normal bone.Histological observations revealed moderate inflammation in the repair area,and the new bone tissues were similar to normal ones.In conclusion,tissue engineered bone of this study exhibited good osteoconductivity for promoting the formation of new alveolar bone tissue,and NELL1 gene played a promotional role in bone regeneration. | Jing Zhang Yang Chen Jing Xu Jingjing Wang Chengzhang Li Liyan Wang | 2018 | Regenerative Biomaterials2018，5，4： | 6 |
| 20 | Fractional Envelope Analysis for Rolling Element Bearing Weak Fault Feature Extraction显示文摘The bearing weak fault feature extraction is crucial to mechanical fault diagnosis and machine condition monitoring.Envelope analysis based on Hilbert transform has been widely used in bearing fault feature extraction. A generalization of the Hilbert transform, the fractional Hilbert transform is defined in the frequency domain, it is based upon the modification of spatial filter with a fractional parameter, and it can be used to construct a new kind of fractional analytic signal. By performing spectrum analysis on the fractional envelope signal, the fractional envelope spectrum can be obtained. When weak faults occur in a bearing, some of the characteristic frequencies will clearly appear in the fractional envelope spectrum. These characteristic frequencies can be used for bearing weak fault feature extraction.The effectiveness of the proposed method is verified through simulation signal and experiment data. | Jianhong Wang Liyan Qiao Yongqiang Ye YangQuan Chen | 2017 | IEEE/CAA Journal of Automatica Sinica2017，4，2： | 5 |
