| 1 | Influence of fault slip on mining-induced pressure and optimization ofroadway support design in fault-influenced zone显示文摘This paper presents an investigation on the characteristics of overlying strata collapse and mininginduced pressure in fault-influenced zone by employing the physical modeling in consideration of fault structure.The precursory information of fault slip during the underground mining activities is studied as well.Based on the physical modeling,the optimization of roadway support design and the field verification in fault-influenced zone are conducted.Physical modeling results show that,due to the combined effect of mining activities and fault slip,the mining-induced pressure and the extent of damaged rock masses in the fault-influenced zone are greater than those in the uninfluenced zone.The sharp increase and the succeeding stabilization of stress or steady increase in displacement can be identified as the precursory information of fault slip.Considering the larger mining-induced pressure in the fault-influenced zone,the new support design utilizing cables is proposed.The optimization of roadway support design suggests that the cables can be anchored in the stable surrounding rocks and can effectively mobilize the load bearing capacity of the stable surrounding rocks.The field observation indicates that the roadway is in good condition with the optimized roadway support design. | Hongwei Wang Yaodong Jiang Sheng Xue Lingtao Mao Zhinan Lin Daixin Deng Dengqiang Zhang | 2016 | Journal of Rock Mechanics and Geotechnical Engineering2016，8，5： | 10 |

| 3 | Solidification/Adsorption of Heavy Metals by FA/FA-MSWI based Al-Substituted Tobermorite显示文摘Fly ash(FA) was utilized to hydrothermally synthesize FA based Al-substituted tobermorites, and was combined with raw materials of FA and municipal solid waste incineration fly ash(MSWI) to hydrothermally synthesize FA-MSWI based Al-substituted tobermorites. Then optimum samples named FA-T and FM-T were selected, correspondingly. Their intrinsic properties as well as their solidification/stabilization and adsorption of heavy metals were studied. The experimental results showed that the specific surface area of FA-T and FM-T was 28.259 m^2/g and 45.939 m^2/g, respectively. Their pore size distribution, particle size distribution, and median particle size were approximately the same. FA-T and FM-T both had great potential of solidification/stabilization heavy metal to dispose hazardous solid waste. Further, FA-T and FM-T also showed good adsorption efficiency for heavy metals Pb2+ and Cu2+ as adsorbent to treat waste water. | 郭晓潞 LI Daixin | 2019 | Journal of Wuhan University of Technology(Materials Science)2019，34，6： | 2 |

| 5 | Ten-year Etiologic Review of Chinese Children Hospitalized for Pediatric Cataracts显示文摘Purpose:Our aim was to obtain a better understanding of the etiologies and characteristics of pediatric cataracts treated at a single facility in China.Methods:.Medical records accrued over a 10-year period(from August, 2003 to July, 2013) at Shengjing Hospital of China Medical University were reviewed retrospectively,ide ntifying all patients treated for various subtypes of pediatric cataract..A database with 367 subjects under 14 years of age(598, including second-round surgeries) was generated.Results:.Of this cohort(n =367; males: 232, 63.2%; females: 135, 36.8%), 200 patients(54.5%) had bilateral cataracts,and 258(70.3%) were under 3 years of age. In all age groups and in all subtypes of pediatric cataract,.males were most commonly affected..Congenital cataract was the most prevalent subtype, accounting for 296 patients(80.7%). Most congenital cataracts were associated with other ocular or systemic abnormalities;.and in 48 patients(16.22%),.they were hereditary..Traumatic cataract was the most common subtype(85.92%) of acquired cataract. The few instances of cataracts due to steroids(n=3) or to metabolic disorders(n=2) occurred in males and involved both eyes.Conclusion: The majority of pediatric cataracts in this patient population were congenital in nature. A significant lag in ophthalmologic evaluation of Chinese infants was evident and should be addressed by educating both children and parents on risk factors for cataract development. Regular assessments are especially important in children subjected to long-term systemic steroid treatments. | Zixun Song Daixin Zhao Cancan Lv Wei Pu Wei Xiao | 2014 | Eye Science2014，29，3： | 1 |

| 9 | Conceptual design and control method for a noncontact annular electromagnetic stabilized satellite platform显示文摘Disturbance-Free Payload(DFP)spacecraft can meet the requirements of ultra-high attitude pointing accuracy and stability for future space missions.However,as the main control actuators of DFP spacecraft,Linear Non-Contact Lorentz Actuators(LNCLAs)have control output problems with six-degree-of-freedom coupling and nonlinear effects,which will affect the attitude control performance of DFP spacecraft.To solve this problem,a novel concept for Non-Contact Annular Electromagnetic Stabilized Satellite Platform(NCAESSP)is proposed in this study.The concept is centered on replacing the LNCLAs with a non-contact annular electromagnetic actuator to solve the two problems mentioned above.Furthermore,for the different control requirements of the payload module and the support module of the NCAESSP,a high-precision attitude controller based on the robust model matching method and a dual quaternion-based adaptive sliding mode controller are proposed.Additionally,the simulation results verify the feasibility and effectiveness of the proposed approach. | He LIAO Daixin WANG Yuan REN Weijie WANG | 2024 | Chinese Journal of Aeronautics2024，37，1： | 0 |

| 11 | Structure adapting of bulk FeS_(2) micron particles and the corresponding anode for high performance sodium-ion batteries显示文摘The practical application of Pyrite iron disulfide (FeS_(2)) as anode material of sodium-ion battery is limitedby its low electronic conductivity, large volume changes during charge/discharge. To overcome thesechallenges, a novel structure design single-walled carbon nanotubes (SWCNTs) composited polyaniline(PANI)-wrapped FeS_(2) (FeS_(2)-PANI-SWCNTs) electrodes are successfully achieved in this work. PANI canprotect the FeS_(2) particles from collapse and offer a protective layer to relive the polysulfides shuttlingeffect, and also promote the electron and Naþ diffusion during the chemical conversion process. Underthe dual protection of PANI and SWCNTs, the FeS_(2)-PANI-SWCNTs film electrode demonstrates a goodstructural integrity, which accounts for the excellent rate capability and long cycling performance. Inaddition, the PANI coating and SWCNT network in the fabricated electrode can synergistically anchorpolysulfides and therefore strongly suppress shuttle effect during the chargeedischarge processes,resulting in less capacity loss. The anode with a loading 3.2 mg cm 2 of FeS_(2) coated with PANI exhibitsthe initial coulombic efficiency of 81.5% and delivers a specific capacity of 625.8 mAh g^(-1) after 100 cyclesat 200 mA g^(-1). High flexible and binder-free FeS_(2)-PANI-SWCNTs film anode demonstrates a reversiblecapacity of 537 mAh g^(-1) after 550 cycles at 1 A g^(-1). This research may offer an efficient method toimprove electrochemical performance of the metal sulfides in sodium-ion batteries. | Yong Li Daixin Ye Wen Liu Rui Guo Haijuan Pei Hongbing Zhao Jiujun Zhang Jingying Xie Jilie Kong | 2022 | Journal of Materiomics2022，8，6： | 0 |
| 12 | Experimental study on the interrelation of multiple mechanical parameters in overburden rock caving process during coal mining in longwall panel显示文摘In order to comprehend the dynamic disaster mechanism induced by overburden rock caving during the advancement of a coal mining face, a physical simulation model is constructed basing on the geological condition of the 21221 mining face at Qianqiu coal mine in Henan Province, China. This study established, a comprehensive monitoring system to investigate the interrelations and evolutionary characteristics among multiple mechanical parameters, including mining-induced stress, displacement, temperature, and acoustic emission events during overburden rock caving. It is suggested that, despite the uniformity of the overburden rock caving interval, the main characteristic of overburden rock lies in its uneven caving strength. The mining-induced stress exhibits a reasonable interrelation with the displacement, temperature, and acoustic emission events of the rock strata. With the advancement of the coal seam, the mining-induced stress undergoes four successive stages: gentle stability, gradual accumulation, high-level mutation, and a return to stability. The variations in other mechanical parameters does not synchronize with the signifcant changes in mining-induced stress. Before the collapse of overburden rock occurs, rock strata temperature increment decreases and the acoustic emission ringing counts surges with the increase of rock strata displacement and mining-induced stress. Therefore, the collaborative characteristics of mining-induced stress, displacement, temperature, and acoustic emission ringing counts can be identifed as the precursor information or overburden rock caving. These results are in good consistent with on-site situation in the coal mine. | Daixin Deng Hongwei Wang Lili Xie Zeliang Wang Jiaqi Song | 2023 | International Journal of Coal Science & Technology2023，10，4： | 0 |
| 13 | SiC JFETs Modular Cascaded Method with Active Clamp Control Strategy for DC Solid-state Circuit Breaker显示文摘Power semiconductor devices cascaded topology is one of the most common solutions for solid-state circuit breakers(SSCBs)working in medium-voltage DC systems.However,when the number of cascaded devices is large,current series technologies of power semiconductor devices will be difficult to be applied since with uneven voltage sharing problems.Thus,this paper proposes a novel cascade method of multi-SiC JFETs based on modules cascaded.This method consists of two parts:one is a single-gate driver cascaded SiC JFETs topology which is used to form the module,the other one is an active clamp control strategy which ensures that each module is protected from overvoltage when modules are cascaded.The proposed cascade method can effectively suppress voltage overshoot of cascading power devices in the switching process.Based on the proposed cascade method,a 5kV/63A SSCB prototype is designed.Finally,an experiment is conducted based on the designed SSCB.Experimental results validate the effectiveness of the proposed cascaded method for SSCB. | Hong Duan Wei Wang Zhikang Shuai Dong He Daixin Chen Z.John Shen | 2023 | CSEE Journal of Power and Energy Systems2023，9，6： | 0 |
