| 1 | Improving CLM4.5 Simulations of Land–Atmosphere Exchange during Freeze–Thaw Processes on the Tibetan Plateau显示文摘Soil is heterogeneous and has different thermal and hydraulic properties, causing varied behavior in heat and moisture transport. Therefore, soil has an important effect on land–atmosphere interactions. In this study, an improved soil parameterization scheme that considers gravel and organic matter in the soil was introduced into CLM4.5(Community Land Model). By using data from the Zoige and Madoi sites on the Tibetan Plateau, the ability of the model to simultaneously simulate the duration of freeze–thaw periods, soil temperature, soil moisture, and surface energy during freeze–thaw processes, was validated. The results indicated that:(1) the new parameterization performed better in simulating the duration of the frozen, thawing, unfrozen, and freezing periods;(2) with the new scheme, the soil thermal conductivity values were decreased;(3) the new parameterization improved soil temperature simulation and effectively decreased cold biases;(4) the new parameterization scheme effectively decreased the dry biases of soil liquid water content during the freezing, completely frozen, and thawing periods, but increased the wet biases during the completely thawed period; and(5) the net radiation, latent heat flux, and soil surface heat flux of the Zoige and Madoi sites were much improved by the new organic matter and thermal conductivity parameterization. | Siqiong LUO Xuewei FANG Shihua LYU Yu ZHANG Boli CHEN | 2017 | Journal of Meteorological Research2017，31，5： | 13 |
| 2 | Simulated effect of soil freeze-thaw process on surface hydrologic and thermal fluxes in frozen ground region of the Northern Hemisphere显示文摘Soil freeze-thaw process is closely related to surface energy budget,hydrological activity,and terrestrial ecosystems.In this study,two numerical experiments(including and excluding soil freeze-thaw process)were designed to examine the effect of soil freeze-thaw process on surface hydrologic and thermal fluxes in frozen ground region in the Northern Hemisphere based on the state-of-the-art Community Earth System Model version 1.0.5.Results show that in response to soil freeze-thaw process,the area averaged soil temperature in the shallow layer(0.0175−0.0451 m)decreases by 0.35℃in the TP(Tibetan Plateau),0.69℃in CES(Central and Eastern Siberia),and 0.6℃in NA(North America)during summer,and increases by 1.93℃in the TP,2.28℃in CES and 1.61℃in NA during winter,respectively.Meanwhile,in response to soil freeze-thaw process,the area averaged soil liquid water content increases in summer and decrease in winter.For surface heat flux components,the ground heat flux is most significantly affected by the freeze-thaw process in both summer and winter,followed by sensible heat flux and latent heat flux in summer.In the TP area,the ground heat flux increases by 2.82 W/m2(28.5%)in summer and decreases by 3.63 W/m2(40%)in winter.Meanwhile,in CES,the ground heat flux increases by 1.89 W/m2(11.3%)in summer and decreases by 1.41 W/m2(18.6%)in winter.The heat fluxes in the Tibetan Plateau are more susceptible to the freeze-thaw process compared with the high-latitude frozen soil regions.Soil freeze-thaw process can induce significant warming in the Tibetan Plateau in winter.Also,this process induces significant cooling in high-latitude regions in summer.The frozen ground can prevent soil liquid water from infiltrating to deep soil layers at the beginning of thawing;however,as the frozen ground thaws continuously,the infiltration of the liquid water increases and the deep soil can store water like a sponge,accompanied by decreasing surface runoff.The influence of the soil freeze-thaw process on surface hydrologic and thermal fluxes varies seasonally and spatially. | Di Ma SiQiong Luo DongLin Guo ShiHua Lyu XianHong Meng BoLi Chen LiHui Luo | 2021 | Research in Cold and Arid Regions2021，13，1： | 4 |

| 4 | An improvement of soil temperature simulations on the Tibetan Plateau显示文摘The simulation of soil temperature on the Tibetan Plateau(TP) plays a dominant role in the performance of both global climate and numerical weather forecast models. To improve the simulation of soil temperature on the TP, the Johansen soil thermal conductivity parameterization scheme was introduced into Community Land Model 3.5(CLM3.5) and Regional Climatic Model 4(Reg CM4). The improved CLM3.5 and Reg CM4-CLM were utilized to conduct offline and regional simulation experiments on the TP. Comparison of the new and old schemes revealed that CLM3.5 provides high thermal conductivity parameters of mineral soil solid on the TP. The Johansen scheme is more practical for the TP than the soil thermal conductivity parameterization in CLM3.5. The simulation of soil temperature and liquid water content was improved in offline experiment. The improved parameterization scheme can also reduce the simulation error of soil temperature in winter throughout the entire TP. | SiQiong Luo BoLi Chen ShiHua Lyu XueWei Fang JingYuan Wang XianHong Meng LunYu Shang ShaoYing Wang Di Ma | 2018 | Research in Cold and Arid Regions2018，10，1： | 2 |

| 8 | Dynamic Characteristics of Lubrication and Wear Prediction of Slipper/Swash-Plate in Axial Piston Pumps显示文摘A novel dynamic model describing the slipper posture of the swash plate in axial piston pumps is proposed, taking into account the hydrodynamic and squeezing effects, which involves three degrees of freedom. The variation in the lubricating film thickness and the slipper tilt are accurately calculated. The influence of hydrodynamic effects and charging pressure on the slipper lubrication is discussed. The minimum film thickness, the overturning angle and the azimuth angle are obtained.Then, the trajectory of minimum thickness on the friction surface of the swash plate is predicted, the accuracy of which can be verified with the abrasion distribution of an actual swash plate. Research results can predict the durability and provide theoretical help for the design of the slipper. | Jichen Zhou Junjie Zhou Chongbo Jing Shihua Yuan Anlin Luo | 2019 | Journal of Beijing Institute of Technology2019，28，3： | 1 |

| 11 | ^(1)O_(2)-activatable Eu^(3+)-afterglow nanoprobe for highly sensitive detection of porphyria in whole blood显示文摘High-sensitivity detection of porphyrin in blood is very important for the early diagnosis and treatment of porphyria.Based on the advantages of longer luminescence lifetime and lower background interference,organic afterglow molecular porphyrin detection probes were developed,but these probes show poor water solubility and insufficient luminescence intensity.Herein,we present an afterglow nanoprobe(Eu-NP)for porphyria detection in whole blood.The luminescent substance(europium complex)and the organic vinyl co mpound reacted with singlet oxygen(^(1)O_(2))were selected for encapsulation in polystyrene spheres.Eu-NP can respond to^(1)O_(2)produced by porphyrins,and the detection signals can be obtained by the emission of the afterglow Eu^(3+)-emissive nanosensor.Eu-NP can achieve high-sensitivity detection of porphyrin,and the lowest detection limit reaches 0.29μmol/L.The porphyrin detection in whole blood samples is consistent with clinical diagnosis results.Compared with the organic afterglow molecule,the Eu-NPs constructed in this work show a higher signal-to-noise ratio and sensitivity of porphyria detection. | Jia Liu Jiamiao Yin Hang Yuan Yiyang Zhao Shihua Luo Fuyou Li | 2022 | Journal of Rare Earths2022，40，9： | 1 |

| 14 | Air Pollution Characteristics and Cause Analysis of Main Urban Area of Western Guizhou in the Ghost Festival显示文摘According to the air quality monitoring and meteorological observation data from 2015 to 2020,the air pollution characteristics and causes were analyzed in the Ghost Festival(on the 15 th of the 7 th lunar month)for the main urban area of Liupanshui City in western Guizhou Province.The results showed that air pollution to different extent occurred in the Ghost Festival every year,reaching the level of heavy pollution in half of the year.The pollution time is generally from 21:00 on the day to 01:00 on the next day.The pollutants mainly come from the smoke dust generated by people burning sacrificial offerings and industrial pollution of iron and steel manufacturing under adverse weather conditions.The primary pollutant is PM 2.5,and the annual variation of pollution shows a downward trend.Precipitation weather is in the majority,which is favorable for reducing the pollution degree;the relationship between wind direction,wind speed and pollution degree is closed;the atmospheric inversion is weak,which has no obvious influence on the change of air pollution;the relative humidity is high,which is conducive to the formation and maintenance of pollution;there is a very significant negative correlation between the degree of air pollution and wind energy,and significantly negative correlation between the degree of air pollution and atmospheric turbulence intensity.Advocating civilized sacrifice and strengthening management is beneficial to reducing the degree of pollution.This paper can be used as a reference for air quality forecasts and taking the appropriate measures to reduce pollution. | Shihua JIANG Ruyong LONG Kun ZHAO Zuoguo LUO Changwen CHEN Lijuan LIU | 2021 | Meteorological and Environmental Research2021，12，1： | 0 |
| 15 | Two-Layer Contact Nonlinear Mechanical Analysis of Flexible Drilling Tool in the Wellbore显示文摘The lack of research on flexible drilling tool leads to limited application of ultra-short radius horizontal wells.The flexible drilling tool is different from the conventional drilling tool.The flexible drilling pipe involves a mutual transition between the structure and the mechanism during the deformation process.At the same time,the flexible drilling pipe and the eccentric guide tube,the guide tube and the wellbore generate random contact.In this paper,3-D beam elements,universal joint elements,rigid beam elements and the beam-beam contact elements are combined to establish a two-layer contact nonlinear finite element model of the flexible drilling tool in the wellbore.The dynamic relaxation method is introduced for numerical solution.The feasibility of the model and the algorithm is verified by an example.The mechanical analysis of flexible drilling tool under the four hole inclinations in the oblique section is carried out.It is found that the flexible drilling pipe has a“folded line”deformation.The contact force between the flexible drilling pipe and the guide tube is randomly distributed.The contact force between the guide tube and the wellbore in the oblique section is greater than that in the vertical section.As the hole inclinations increase,the torque and axial force transmitted to the drill bit gradually decrease. | Min Luo Tingting Xu Jiajun Jiang Xu Chi Jing Wang Shihua Xue | 2020 | Computer Modeling in Engineering & Sciences2020，，4： | 0 |

| 17 | Characteristics and Genesis of Acid Drainage Contamination from a Rock Tunneling Project Site显示文摘While acid mine drainage(AMD)issues have become a topic of global concern,few studies have focused on acid drainage problems of non-mining activities.We conducted field research and a series of laboratory experiments to investigate the characteristics,release processes and formation of acid drainage contamination.Spoil rock samples and adjacent surface water,groundwater,soil and sediment samples were collected at a railway tunnel construction site in central China,and various parameters,such as the p H,mineral ion concentrations,and heavy metal concentrations,were measured.Based on the measured concentrations,surface water and sediments were seriously contaminated by acids,sulfate salts and heavy metals.Contamination in surface water showed a decreasing tendency as the distance from the spoils increased,while that in sediments showed a greater influence of coprecipitation and adsorption processes of heavy metal ions.The eluviation experiments of three rock samples indicated that R2(silty fine sandstone)was the most likely major acid drainage contributor.Thiobacillus ferrooxidans was cultured and isolated from contaminated water to study the oxidation conditions during the release processes.The significant release of acid drainage when air and bacteria were both in the culture container suggested that oxygen and bacteria were necessary to produce acid drainage from spoils. | Yanyun Li Zejiao Luo Shihua Qi | 2024 | Journal of Earth Science2024，35，1： | 0 |

| 19 | Tectonic boundaries in the South China Sea from aeromagnetic signature显示文摘Magnetic data has been widely applied in the tectonic division.High-resolution magnetic data were used to analyze the geotectonic zoning of the South China Sea.Based on the newly compilated magnetic data,the processing results and the distribution of known faults,we consider that the U-shaped line approximately along the South China Sea national boundary of China shown in the magnetic map is a significant geological and geophysical boundary.We first described the linear characteristics of the magnetic data and then applied pseudo-gravity,Euler deconvolution,tilt derivatives,and the texture segmentation method to process the data.Results show that the dividing line between the South China Sea and the surrounding blocks is approximately along this U-shaped line.The dividing line between the South China domain and the South China Sea domain is along with the Dongsha Islands to Xisha Trough,which is different from the previous geophysical zoning results.Our results are almost consistent with those of the gravity data indicating roughly the tectonic zonation along the U-shaped line. | Yao LUO Hang YIN Qiang LIU Jingmin LI Shihua LIU Wei GAO Rui LI Yi YANG | 2023 | Journal of Oceanology and Limnology2023，41，2： | 0 |
| 20 | Winter estimation of surface roughness length over eastern Qinghai-Tibetan Plateau显示文摘Based on the Monin-Obukhov similarity theory, a scheme was developed to calculate surface roughness length. Surface roughness length over the eastern Qinghai-Tibetan Plateau during the winter season was then estimated using the scheme and eddy covariance measurement data. Comparisons of estimated and measured wind speeds show that the scheme is feasible to calculate surface roughness length. The estimated roughness lengths at the measurement site during unfrozen,frozen and melted periods are 3.23×10-3, 2.27×10-3 and 1.92×10-3 m, respectively. Surface roughness length demonstrates a deceasing trend with time during the winter season. Thereby, setting the roughness length to be a constant value in numerical models could lead to certain degree of simulation errors. The variation of surface roughness length may be caused by the change in land surface characteristic. | LunYu Shang Yu Zhang ShiHua Lyu ShaoYing Wang YinHuan Ao SiQiong Luo ShiQiang Chen | 2017 | Research in Cold and Arid Regions2017，9，2： | 0 |
