| 2 | A Nonlinear Observer Approach of SOC Estimation Based on Hysteresis Model for Lithium-ion Battery显示文摘In this paper, a state of charge(SOC) estimation approach for lithium-ion battery based on equivalent circuit model and the input-to-state stability(ISS) theory has been proposed. According to the electrochemical performance of lithiumion battery, the equivalent circuit model with two RC networks is established, which includes hysteresis characteristic in inner electrochemical response process. The nonlinear relation between open circuit voltage(OCV) and SOC is obtained from a rapid test. Exponential fitting method is used to identify the parameters of the model. A novel state observer based on ISS theory is designed for lithium-ion battery SOC estimation. The designed observer is tested on AMESim and Simulink co-simulation. The simulation results show that the proposed method has a high SOC estimation accuracy with an error of about 2 percent. | Yan Ma Bingsi Li Guangyuan Li Jixing Zhang Hong Chen | 2017 | IEEE/CAA Journal of Automatica Sinica2017，4，2： | 7 |

| 10 | R&D of BEPCII 500 MHz superconducting cavity显示文摘Beijing Electron-Positron Collider Upgrade (BEPCII) adopts two 500 MHz superconducting cavities (SCCs) in each ring for higher accelerated gradient, higher Q and lower impedance (Wang et al. The proceedings of SRF'07). There's no spare cavity due to the limited time and funding during BEPCII construction. If any serious trouble happened on either one of the two cavities and could not be recovered in a short time, the operation of BEPCII facility will be affected. Therefore, since 2009 three spare cavities have been fabricated in China to ensure reliable operation, and two of them have been successfully vertically tested in January and July 2011. This paper will briefly present the manufacture, post-process and vertical test performance of the 500 MHz spare cavities. | LIU YaPing WANG GuangWei PAN WeiMin LI JiZhen LIU DeGui SUN Yi LI ZhongQuan DAI JianPing LI ShaoPeng HE Kun WANG GuoPing ZHAO GuangYuan MA Qiang LIN HaiYing SHA Peng WANG QunYao QIU Feng MENG FanBo LI Han | 2011 | Science China(Physics,Mechanics & Astronomy)2011，54，S2： | 0 |
| 11 | Officials'Foreign Experience and Firms'Exports:Evidence from China显示文摘This study examines how the foreign experience of local oficials affects firms'exports in China.Using a matched sample from 2000 to 2012,we found that the foreign experience of municipal Party secretaries had a significant impact on the promotion of firms'exports,especially for private firms.This positive impact was more pronounced when officials went abroad at a younger age,stayed abroad for a longer period,returned to China for a longer time,and had greater promotion incentives.We found that officials'foreign experience helped to mitigate the negative impact of institutional distance and provided firms with better access to export subsidies,both of which could promote exporting.There was also a complementary effect when officials and executives both had foreign experience.Overall,our study provides some insights into the economic outcomes of officials'foreign experience and sheds light on the export performance of Chinese firms. | Yekun Xu Guangyuan Ma Lijuan Cui | 2023 | China & World Economy2023，31，3： | 0 |

| 15 | Excess PbI_(2)evolution for triple-cation based perovskite solar cells with 21.9%efficiency显示文摘The triple cation mixed perovskites(Cs FAMA)are known as one of the most efficient candidates for perovskite solar cells(PSCs).It is found that the power conversion efficiency(PCE)of triple-cation based devices would increase with the test time extending,and the maximum efficiency is normally obtained after several days aging storage.Here,the relationship between enhanced device performance,excess PbI_(2)and its evolution in triple cation perovskite films of initial days was systematically explored.The Cs FAMA-PSCs are prepared by two-step methods under two environmental conditions,including in the glove box and the ambient air(30%humidity).After 7 days testing,the maximum PCE of PSCs under two conditions dramatically increased 12.4%and 12.2%,reached 21.68%and 21.89%,respectively.At initial days,the XRD peak intensities of perovskite phase gradually decreased and those corresponding to PbI_(2)increased.Along with time-resolved photoluminescence(TRPL)and kelvin probe force microscopy(KPFM),it was found that the defects were passivated with the evolution of PbI_(2).This work reveals the excess PbI_(2)and its evolution in perovskite film,which can further supplement the understanding of PbI_(2)defect passivation. | Zhu Ma Dejun Huang Qianyu Liu Guangyuan Yan Zheng Xiao Dong Chen Jiaxuan Zhao Yan Xiang Changtao Peng Haijin Li Meng Zhang Wenfeng Zhang Lianfeng Duan Yuelong Huang | 2022 | Journal of Energy Chemistry2022，31，3： | 0 |

| 17 | Highly efficient and selective removal of phosphate from wastewater of sea cucumber aquaculture for microalgae culture using a new adsorption-membrane separation-coordinated strategy显示文摘Enhanced phosphorus treatment and recovery has been continuously pursued due to the stringent wastewater discharge regulations and a phosphate supply shortage. Here, a new adsorption-membrane separation strategy was developed for rational reutilization of phosphate from sea cucumber aquaculture wastewater using a Zr-modified-bentonite filled polyvinyl chloride membrane. The as-obtained polyvinyl chloride/Zr-modified-bentonite membrane was highly permeability (940 L/(m2·h)), 1–2 times higher than those reported in other studies, and its adsorption capacity was high (20.6 mg/g) when the phosphate concentration in water was low (5 mg/L). It remained stable under various conditions, such as different pH, initial phosphate concentrations, and the presence of different ions after 24 h of adsorption in a cross-flow filtration system. The total phosphorus and phosphate removal rate reached 91.5% and 95.9%, respectively, after the membrane was used to treat sea cucumber aquaculture wastewater for 24 h and no other water quality parameters had been changed. After the purification process, the utilization of the membrane as a new source of phosphorus in the phosphorus-free f/2 medium experiments indicated the high cultivability of economic microalgae Phaeodactylum tricornutum FACHB-863 and 1.2 times more chlorophyll a was present than in f/2 medium. The biomass and lipid content of the microalgae in the two different media were similar. The innovative polyvinyl chloride/Zr-modified-bentonite membrane used for phosphorus removal and recovery is an important instrument to establish the groundwork for both the treatment of low concentration phosphate from wastewater as well as the reuse of enriched phosphorus in required fields. | Aihua Zhang Shihao Fang Huan Xi Jianke Huang Yongfu Li Guangyuan Ma Jianfeng Zhang | 2023 | Frontiers of Environmental Science & Engineering2023，17，10： | 0 |
