| 1 | A displacement-relay videometric method for surface subsidence surveillance in unstable areas显示文摘When measuring the surface subsidence of unstable areas such as railroad beds and large construction fields, it is not practical to always find stable positions to install measurement instruments. Yet installing those instruments in unstable positions will cause measurement errors or even the complete failure of long-term subsidence surveillance. In this paper, the innovative concept and its method of 'displacement-relay videometrics' are proposed. With the method, a double-headed camera is designed, and two constraints, the 'fixation constraint' and the 'homologous constraint', are established to construct the displacement-relay measurement equations, which can concurrently give the subsidence of the points to be measured and the positions where the cameras are fixed. The method and its measurement system are thus capable of automatically measuring the surface subsidence under the condition that the cameras are mounted on unstable locations over long durations. Therefore, the method has the broad prospect of undertaking automatic, long-term and continuous measurement for surface subsidence in engineering projects such as railroad beds, bridges and the ground beds of tall buildings. The proposed method opens a new area that cameras can be mounted on unstable platform to make high accuracy measurements, which is of great significance for applications. | YU QiFeng JIANG GuangWen SHANG Yang XU Yong LIU XiaoLin FU SiHua GUAN BangLei ZHU XianWei | 2015 | Science China(Technological Sciences)2015，58，6： | 5 |

| 4 | Polyaniline nanostructures tuning with oxidants in interfacial polymerization system显示文摘Three kinds of nanostructured polyanilines(PANIs) were prepared through interfacial polymerization by using ammonium persulfate(APS) as a single oxidant,and APS/FeCl_3,APS/K_2Cr_2O_7 as composite oxidants,respectively.It is observed that faster formation process and higher yield of nanostructured PANIs could be achieved in the presence of FeCl_3 and K_2Cr_2O_7.The as-prepared PANIs were characterized by field emission scanning electron microscopy,ultraviolet-visible absorption spectroscopy,Fourier transform infrared and Raman spectroscopy,X-ray diffraction analysis and electrochemical measurements including cyclic voltammetry and galvanostatic charge/discharge measurement.The influence of composite oxidants on the morphology,microstructure,and electrical and electrochemical properties of PANIs was discussed.Interestingly,when APS/K_2Cr_2O_7 was used as the composite oxidants,PANI exhibited petal-like structure with high yield of 57.35%instead of general nanofibrous morphology formed in interfacial polymerization.Compared with those nanofibrous PANIs obtained by using APS as a single oxidant or APS/FeCl_3 as composite oxidants,petal-like PANIs exhibited the largest specific capacitance(692.4 F/g at scan rate of 5 mV/s) and highest cycle stability among them.It provides a new insight into the control of PANI nanostructures with high yield and energy storage ability by simply selecting suitable composite oxidants in interfacial polymerization. | Fanxin Zeng Zongyi Qin Banglei Liang Tao Li Na Liu Meifang Zhu | 2015 | Progress in Natural Science:Materials International2015，25，5： | 0 |
| 5 | Musicality of Le Clezio’s Novels显示文摘Le Clezio takes his novels as art and imbues his novels with elements of music,which abound in his novels.He strikes to present his novels in an artistic way by combining words and the music,thus showing his great concern for the soul and well-being of human kind.This thesis probes into how musical elements are used in his novel to construct identity,make language of the novels musical,and offer a narrative structure. | LIAO Banglei | 2019 | Sino-US English Teaching2019，16，12： | 0 |

| 7 | Multiple rotation averaging using only the relative rotation angle显示文摘In this work,we propose multiple rotation averaging using only the relative rotation angle,which is a straightforward camera pose optimization method.We use the axis-angle representation to parameterize the rotation and use only relative rotation angles to constrain absolute rotations instead of complete relative rotations.When used with an inertial measurement unit(IMU),our method can obviate the need to estimate and maintain extrinsic parameters between the camera and IMU.This advantage makes our method immune to extrinsic parameters and flexible.We performed extensive evaluations on both synthetic data and publicly available real datasets,which showed that our method was comparable with the state-of-the-art method and achieved a significant gain in accuracy for the visual measurement when applied to the case in which the camera and IMU are tightly fixed. | LI Bin SHANG Yang GUAN BangLei LIANG ShunKun SUN XiaoLiang YU QiFeng | 2023 | Science China(Technological Sciences)2023，66，10： | 0 |
