    STUDY ON ENERGY ABSORPTION CHARACTERISTIC OF SINUSOIDAL BELLOWS FILLED EMULSION ABSORBER by ZHANG JianZhuo, ZHANG WanJiu, PAN YiShan, GUO Hao, WANG ShuWen

    Published 2024-10-01
    “…The pre⁃folded energy absorber is the only energy absorber structure used in rock burst mine at present.It has excellent energy absorption characteristics,but there are some problems in the buckling deformation process such as large load fluctuation and spark due to friction.In view of the above situation,a sinusoidal bellows(reduced diameter round pipe)filled with emulsion was designed to form a solid⁃liquid coupling body energy absorption component(composite component).The effects of three factors,namely wall thickness of the bellows,amplitude of the busbar and diameter of the liquid outlet,on the energy absorption characteristics of the energy absorption component were studied.The prediction model of average load,load fluctuation coefficient and specific energy absorption was established.The smoothed partiole hydrodynamics(SPH)particle algorithm of Abaqus finite element software was used for fluid⁃structure coupling analysis of the model.The structural parameters of energy absorption components were optimized by response surface method and the optimization results were obtained.The results show that when the wall thickness of corrugated pipe is 3.959 mm,the amplitude of busbar is 3.721 mm,and the diameter of outlet is 22.161 mm,the energy absorption characteristics of the member are the best.The average load is 438.684 kN,the load fluctuation coefficient is 1.178,and the specific energy absorption is 12.123 kJ/kg.Through comparison and verification,the results have high reliability,which provides a superior energy absorption component for the energy absorption link of anti⁃impact support equipment.…”

    Changes in habitat suitability for wintering dabbling ducks during dry conditions in the Central Valley of California by Erin E. Conlisk, Kristin B. Byrd, Elliott Matchett, Austen A. Lorenz, Michael Casazza, Gregory H. Golet, Mark D. Reynolds, Kristin A. Sesser, Matthew E. Reiter

    Published 2023-01-01
    “…Using abundance‐weighted boosted regression trees, we created three sets of species occurrence models based on different covariates: (1) near real‐time (hereafter “real‐time”) covariates in which duck observations were matched to the water availability within the 16‐day window of a Landsat observation, (2) a combination of real‐time covariates and waterfowl food resource covariates describing annual corn and rice biomass and managed wetland moist soil seed yield estimates derived from Landsat data, and (3) long‐term average covariates—the most common approach to species distribution modeling—in which long‐term average surface water availability was used. …”

    3-5 μm Mid-Infrared Broadband Perfect Absorber Based on Ti Ring Embedded Structure by Yun Fang, Li Gong, Sixuan Huang, Shuzhan Yan, Xue Zhang

    Published 2023-01-01
    “…The excellent absorption at 3-5 μm is attributed to the intrinsic absorption of the two dielectrics and the excitation of the surface plasmon resonance (SPR). Moreover, the average absorption rate can be still maintained above 91.33% when the incident angle of TE/TM or unpolarized wave reaches 60°, and there is almost unchanged in the absorption rate when the polarization angle of the incident wave gradually changes from 0° to 90°, which shows the insensitivity of the absorber to the incident and polarization angle. …”

    Performance Evaluation of CLM5 in Simulating Evapotranspiration over Pearl River Basin by WANG Dayang

    Published 2022-01-01
    “…To investigate the simulation performance of the Community Land Model version 5 (CLM5) in simulating terrestrial evapotranspiration,this paper simulated the surface processes in the Pearl River Basin (PRB) from 1989 to 2018 with CLM5.For validation,the remote sensing-based GLEAM ET products were used as reference for the evaluation of the model's simulation performance.The evaluation was based on temporal variability analysis and spatial pattern analysis.The results show that CLM5 underestimates the evapotranspiration in the PRB to varying degrees,with the relative error of average annual evapotranspiration being -16.07% in the basin.The underestimation is mainly attributed to the underestimation of low evapotranspiration in the cold season. …”
