| 1 | Reconstruction of the shape of object with near field measurements in a half-plane显示文摘We consider a mathematical problem modelling some characteristics of near field optical microscope.We take a monofrequency line source to illuminate a sample with constant index of refraction and use the scattered field data measured near the sample to reconstruct the shape of it. Mixed reciprocity relation and factorization method are applied to solve our problem.Some numerical examples to show the feasibility of the method are presented. | DONG HePing MA FuMing | 2008 | Science China Mathematics2008，51，6： | 4 |

| 3 | An ultrahigh strength steel produced through deformation-induced ferrite transformation and Q&P process显示文摘In this work,DIFT technology and Q&P process were combined in order to introduce ultrafine-grained ferrite into the matrix of martensite and retained austenite to develop a new kind of advanced high strength steel,and two kinds of steels were investigated by this novel combined process.The newly designed process resulted in a sophisticated microstructure of a large amount of ferrite(about 5 m in diameter),martensite and a considerable amount of retained austenite for TRIP 780 steel.The ultimate tensile strength can reach about 1200 MPa with elongation above 16% for TRIP 780,that is much higher than the one solely treated by Q&P process.Tensile tests showed that both steels with the novel combined process achieved a good combination of strength and ductility,indicating that the new process is promising for the new generation of advanced high strength steels. | CHEN MingMing WU RiMing LIU HePing WANG Li SHI Jie DONG Han JIN XueJun | 2012 | Science China(Technological Sciences)2012，55，7： | 3 |
| 4 | Miniature Fluorescence Microscopy for Imaging Brain Activity in Freely-Behaving Animals显示文摘An ultimate goal of neuroscience is to decipher the principles underlying neuronal information processing at the molecular,cellular,circuit,and system levels.The advent of miniature fluorescence microscopy has furthered the quest by visualizing brain activities and structural dynamics in animals engaged in self-determined behaviors.In this brief review,we summarize recent advances in miniature fluorescence microscopy for neuroscience,focusing mostly on two mainstream solutions-miniature single-photon microscopy,and miniature two-photon microscopy.We discuss their technical advantages and limitations as well as unmet challenges for future improvement.Examples of preliminary applications are also presented to reflect on a new trend of brain imaging in experimental paradigms involving body movements,long and complex protocols,and even disease progression and aging. | Shiyuan Chen Ziehen Wang Dong Zhang Aiming Wang Liangyi Chen Heping Cheng Runlong Wu | 2020 | Neuroscience Bulletin2020，36，10： | 2 |
| 5 | Li-ion battery material under high pressure:amorphization and enhanced conductivity of Li_4Ti_5O_(12)显示文摘Lithium titanium oxide(Li_4Ti_5O_(12),LTO),a‘zero-strain’anode material for lithium-ion batteries,exhibits excellent cycling performance.However,its poor conductivity highly limits its applications.Here,the structural stability and conductivity of LTO were studied using in situ high-pressure measurements and first-principles calculations.LTO underwent a pressure-induced amorphization(PIA)at 26.9 GPa.The impedance spectroscopy revealed that the conductivity of LTO improved significantly after amorphization and that the conductivity of decompressed amorphous LTO increased by an order of magnitude compared with its starting phase.Furthermore,our calculations demonstrated that the different compressibility of the Li O_6 and Ti O_6 octahedra in the structure was crucial for the PIA.The amorphous phase promotes Li^+ diffusion and enhances its ionic conductivity by providing defects for ion migration.Our results not only provide an insight into the pressure depended structural properties of a spinel-like material,but also facilitate exploration of the interplay between PIA and conductivity. | Yanwei Huang Yu He Howard Sheng Xia Lu Haini Dong Sudeshna Samanta Hongliang Dong Xifeng Li Duck Young Kim Ho-kwang Mao Yuzi Liu Heping Li Hong Li Lin Wang | 2019 | National Science Review2019，6，2： | 2 |

| 12 | Spatial Distribution and Controlling Factors of Sedimentary Bodies in Jiaozhou Bay and Adjacent Sea Areas, Qingdao显示文摘The distributions of thickness of unconsolidated Quaternary sedimentary layers in Jiaozhou Bay and Qingdao offshore area were studied by using 1079-km high-resolution shallow seismic profiles and drilling core data, and the factors controlling the Quaternary evolution were discussed. The results show that such thickness distributions resulted from the coactions of geologic structures and marine hydrodynamic conditions since the Holocene. The geologic structures controlled the slope deposit, proluvial and fluvial fillings since the late Pleistocene. Holocene marine hydrodynamics eroded away sediments at the bay mouth, and tides carried these eroded materials to the sides of the bay mouth and released them there, forming channel-ridge-alternating geomorphic features. During transgressive processes, the sea level rose rapidly, and insufficient sediment supply and tidal actions yielded the relict sediments in the east of Qingdao offshore area. | DONG Heping LI Guangxue LI shuanglin LI Shaoquan LI Chun | 2011 | Journal of Ocean University of China2011，10，2： | 1 |

| 20 | Differences of Soil Nutrient Contents under Different Land Use Patterns in Niyang River Basin显示文摘[Objectives]This study was conducted to investigate the variation characteristics of soil nutrient contents under different land use patterns in the middle and upper reaches of the Niyang River in Tibet.[Methods]With the cultivated land,grass land and forest land in the middle and upper reaches of the Niyang River as the research objects,216 soil samples were collected in layers(0-10,10-20,20-30 cm)by the standard sampling method,and the soil total nitrogen,alkali-hydrolyzable nitrogen,total potassium,available potassium,total phosphorus,available phosphorus and organic matter were determined.[Results]The contents of soil organic matter,total nitrogen and alkali-hydrolyzable nitrogen in the middle and upper reaches of Niyang River in Tibet ranked as forest land>grass land>cultivated land,and there were significant differences between the three(P<0.05).The total potassium contents of grass land and forest land were not much different,and the contents of available potassium exhibited an order of forest land>grass land>cultivated land.The distribution of soil total nutrients and available nutrients under different land use patterns showed a certain degree of surface aggregation.The contents of total nutrients and available nutrients in the soil at the 0-10 cm depth were significantly higher than those at 10-20 and 20-30 cm,and there were significant differences between the three(P<0.05).The average content of alkali-hydrolyzable nitrogen was the largest in forest soil and the smallest in cultivated land under the three land use patterns in the study area.The average content of soil available phosphorus in cultivated land(19.47 mg/kg)was significantly higher than those in grass land(5.73 mg/kg)and forest land(5.19 mg/kg).The above results indicate that long-term vegetation restoration can improve the soil quality of the middle and upper reaches of the Niyang River.[Conclusions]The results of this study research provide basic support for improving the soil effect in the area. | Heping MA Zhu DONG | 2022 | Agricultural Biotechnology2022，11，2： | 0 |
