| 1 | Using lightning locating system based on time-of-arrival technique to study three-dimensional lightning discharge processes显示文摘A time-of-arrival(TOA) system based on GPS technology for locating VHF radiation sources from lightning has been developed and used in observation sites in the northern Shandong Province,China.The 3D images of the lightning progression have been obtained successfully for the first time in China.The 3D-channel evolutions of typical negative CG,positive CG and IC lightning flashes have been discussed together with the data of fast electric field change.It was found that significant differences existed between the negative and positive CG lightning flashes in terms of the initiation and propagation of the radiation sources.The preliminary breakdown of a negative CG lightning flash propagated at a speed about 5.2×104 m/s.The stepped leader of negative CG lightning flashes was trigged by negative initial breakdown.Thereafter,it propagated downward at a speed of 1.3×105 m/s.The initial process of the positive CG lightning flashes was also a propagation process of negative streamer.These streamers propagated dominantly horizontally in the positive charge region and accumulated positive charges at the origin of the lightning,and as a consequence,initiated downward positive streamers.A new type of lightning discharge that was triggered by a narrow bipolar pulse(NBP) is discussed in this study.The NBP was originated at altitude of about 10.5 km in the upper positive charge region.As a distinct difference from normal IC flash,its channels extended horizontally all around and produced a lot of radiation sources.The source power of the NBP could approach 16.7 kW,which is much greater than that of normal lightning discharge ranging between 100 mW and 500 W.The 3D propagation of this new type of lightning discharge was observed and obtained for the first time in China.The possible initiation mechanism of this new type of light-ning is discussed here. | ZHANG GuangShu1,WANG YanHui1,QIE XiuShu2,ZHANG Tong1,ZHAO YuXiang1,3,LI YaJun1 & CAO DongJie11 Laboratory for Climate Environment and Disasters of Western China,Cold and Arid Regions Environmental and Engineering Research Institute,Chinese Academy of Sciences,Lanzhou 730000,China 2 Laboratory for Middle Atmosphere and Global Environment Observation(LAGEO),Institute of Atmospheric Physics,Chinese Academy of Sciences,Beijing 100029,China 3 Department of Physics,Tianshui Normal College,Tianshui 741001,China | 2010 | Science China Earth Sciences2010，53，4： | 21 |

| 6 | Estimating the quality of stripe in structured light 3D measurement显示文摘Affected by noise, light blocking, color and shape of object, the quality of captured stripes in structured light three dimensional(3 D) measurement system is degenerated. As the quality of captured stripes is one of the key factors for measurement accuracy, some large error data is introduced into the measurement results which can only be recognized artificially with prior knowledge of the object to be measured. In this paper, a method is proposed to estimate the quality of stripe image. In the method, two parameters, skewness coefficient of stripe gray distribution and the noise level, are used to estimate the quality of stripe. The simulation results show that the bigger the skewness coefficient is, the bigger the error of stripe locating results is. Meanwhile, the smaller the noise level is, the smaller the error of stripe locating results is. The method has been used to estimate the experimental image, and the same conclusion can be obtained. The method can be used for recognizing large error data automatically by the two parameters. | XUE Qi JI Wenzhao MENG Hao SUN Xiaohong YE Huiying YANG Xiaonan | 2022 | Optoelectronics Letters2022，18，2： | 2 |
| 7 | A Locating Method for Reliability-Critical Gates with a Parallel-Structured Genetic Algorithm显示文摘The reliability allowance of circuits tends to decrease with the increase of circuit integration and the application of new technology and materials, and the hardening strategy oriented toward gates is an effective technology for improving the circuit reliability of the current situations. Therefore, a parallel-structured genetic algorithm (GA), PGA, is proposed in this paper to locate reliability-critical gates to successfully perform targeted hardening. Firstly, we design a binary coding method for reliability-critical gates and build an ordered initial population consisting of dominant individuals to improve the quality of the initial population. Secondly, we construct an embedded parallel operation loop for directional crossover and directional mutation to compensate for the deficiency of the poor local search of the GA. Thirdly, for combination with a diversity protection strategy for the population, we design an elitism retention based selection method to boost the convergence speed and avoid being trapped by a local optimum. Finally, we present an ordered identification method oriented toward reliability-critical gates using a scoring mechanism to retain the potential optimal solutions in each round to improve the robustness of the proposed locating method. The simulation results on benchmark circuits show that the proposed method PGA is an efficient locating method for reliability-critical gates in terms of accuracy and convergence speed. | Jie Xiao Zhan-Hui Shi Jian-Hui Jiang Xu-Hua Yang Yu-Jiao Huang Hai-Gen Hu | 2019 | Journal of Computer Science & Technology2019，34，5： | 1 |
| 8 | Propagation and localisation of partial discharge in transformer bushing based on ultra-high frequency technique显示文摘As an essential component of power transformers,the detection and diagnosis of incipient partial discharge(PD)activities of bushings are of great significance.A 35-kV oil-impregnated paper(OIP)bushing is investigated.The bushing is modelled by coaxial theory and electromagnetic(EM)simulation.As the paths of PD-induced ultra-high frequency(UHF)signal propagating in the bushing are OIPs and oil gap,small attenuation during signal propagation is seen.Since OIP is composed of het-erogeneous media compared with pure oil,there will be relatively less UHF signal leakage from OIPs,whereas more leakage from the oil gap.This leakage provides the possibility of non-contact detection outside the bushing by UHF method.PD mea-surements with UHF method are carried out on the bushing.Then,the minimum energy method is used to extract time-difference-of-arrival(TDOA),and Chan al-gorithm is adopted to locate points of UHF signal radiation.High accuracy locating with a small error of 15 cm has been achieved.The contactless UHF method-based tests have demonstrated the effectiveness of online monitoring and locating of bushing PD. | Jun Jiang Judong Chen Jiansheng Li Xiaoping Yang Ricardo Albarracín-Sánchez Prem Ranjan Chaohai Zhang | 2021 | High Voltage2021，6，4： | 1 |

| 10 | A wall-thickness compensation strategy for wax pattern of hollow turbine blade显示文摘As an important index affecting the aerodynamic performance and the structural strength of hollow turbine blades, the wall-thickness precision of the blade is mainly inherited from the positional relationship between the corresponding wax pattern and the internal ceramic core.However, due to locating errors, the actual position of ceramic core is always deviated from the ideal position, which makes it difficult to guarantee the wall-thickness precision of the wax pattern.To solve this problem, a wall-thickness compensation strategy is proposed in this paper. Firstly,based on the industrial computed tomography(ICT) technique and curve matching algorithms, a model reconstruction method is developed, with which the 3D model of a trial wax pattern can be easily constructed. After that, focusing on eliminating the wall-thickness errors of the trial wax pattern, an optimization method for the pose of the ceramic core in the wax pattern is proposed. Then, by mapping the optimal pose of the ceramic core to length adjustments of the locating rods, the wall-thickness errors of the wax pattern can be greatly reduced. A case study is also given to illustrate the effectiveness of the proposed compensation strategy. | Kang CUI Wenhu WANG Ruisong JIANG Dezhong ZHAO | 2019 | Chinese Journal of Aeronautics2019，32，8： | 1 |

| 12 | Novel Superconducting Electrides in Ca–S System under High Pressures显示文摘Due to their unique structure properties,most of the electrides that possess extra electrons locating in interstitial regions as anions are insulators.Metallic and superconducting electrides are very rare under ambient conditions.We systematically search possible compounds in Ca-S systems stabilized under various pressures up to 200 GPa,and investigate their crystal structures and properties using first-principles calculations.We predict a series of novel stoichiometries in Ca-S systems as potential superconductors,including P2_(1)/m Ca_(3)S, Pnma Ca_(3)S,Pnma Ca_(2)S,Cmcm Ca_(2)S,Fddd CaS_(2),Immm CaS_(3) and C2/c CaS_(4).The P4mbm Ca_(3)S phase exhibits a maximum Tc value of ~20K.It is interesting to notice that the P2_(1)/m Ca_(3)S and Pnma Ca_(2)S stabilized at 60 and 50 GPa behave as superconducting electrides with critical temperatures Tc of 7.04 K and 0.26 K,respectively.More importantly,our results demonstrate that P2_(1)/m Ca_(3)S and Pnma Ca_(2)S are dynamically stable at 5 GPa and 0 GPa,respectively,indicating a high possibility to be quenched to ambient condition or synthesized using the large volume press. | 刘云仙 王超 韩帅 陈欣 孙海瑞 刘晓兵 | 2021 | Chinese Physics Letters2021，38，3： | 0 |
| 13 | Biological Parts for Plant Biodesign to Enhance Land-Based Carbon Dioxide Removal显示文摘A grand challenge facing society is climate change caused mainly by rising CO_(2) concentration in Earth’s atmosphere.Terrestrial plants are linchpins in global carbon cycling,with a unique capability of capturing CO_(2) via photosynthesis and translocating captured carbon to stems,roots,and soils for long-term storage.However,many researchers postulate that existing land plants cannot meet the ambitious requirement for CO_(2) removal to mitigate climate change in the future due to low photosynthetic efficiency,limited carbon allocation for long-term storage,and low suitability for the bioeconomy.To address these limitations,there is an urgent need for genetic improvement of existing plants or construction of novel plant systems through biosystems design(or biodesign).Here,we summarize validated biological parts(e.g.,protein-encoding genes and noncoding RNAs)for biological engineering of carbon dioxide removal(CDR)traits in terrestrial plants to accelerate land-based decarbonization in bioenergy plantations and agricultural settings and promote a vibrant bioeconomy.Specifically,we first summarize the framework of plant-based CDR(e.g.,CO_(2) capture,translocation,storage,and conversion to value-added products).Then,we highlight some representative biological parts,with experimental evidence,in this framework.Finally,we discuss challenges and strategies for the identification and curation of biological parts for CDR engineering in plants. | Xiaohan Yang Degao Liu Haiwei Lu David J.Weston Jin-Gui Chen Wellington Muchero Stanton Martin Yang Liu Md Mahmudul Hassan Guoliang Yuan Udaya C.Kalluri Timothy J.Tschaplinski Julie C.Mitchell Stan D.Wullschleger Gerald A.Tuskan | 2021 | BioDesign Research2021，，1： | 0 |

| 19 | Sniffing with mass spectrometry显示文摘Gaseous compounds are usually on-line detectable on sensors. The limitations of conventional sensors are suffering from incapability for exactly identifying multiple components as well as incompatibility to possible toxicants in every odor sample. Herein, we discuss an inlet modification to the laboratory standard mass spectrometer, inspired by the sensitive olfactory systems of animals, for direct sniffing,established by connecting a mini pump to the nebulizer gas tubing. The modified mass spectrometry method—sniffing-mass spectrometry(sniffing-MS)—can acquire detailed fingerprint spectra of mixed odors and shows high tolerance to toxicants. Furthermore, the method has a low limit of detection in the order of parts per trillion and is a ‘sampling-free' technique for analyzing various gaseous compounds simultaneously, thus offering versatility for smelling daily commodities, tracking diffusion, and locating position of odors. Sniffing-MS can mimic or even surpass the olfaction of animals and is applicable for analyzing gaseous/volatile compounds, especially those polar compounds, in a simple manner depending on the intrinsic molecular mass-to-charge ratio. | Miao-Miao Chen Hai-Feng Su Ying Xie Li-Fang He Shui-Chao Lin Mei-Lin Zhang Cheng Wang Su-Yuan Xie Rong-Bin Huang Lan-Sun Zheng | 2018 | Science Bulletin2018，63，20： | 0 |
