| 1 | Water in the Mogao Grottoes,China:where it comes from and how it is driven显示文摘The Dunhuang Mogao Grottoes in China was designated as a world heritage site by UNESCO in 1987 and is famous for its cultural relics. Water is the most active factor that harms the relics in the caves as it damages the grotto murals and painted sculptures. Thus, determining the water sources and driving forces of water movement is a key issue for protecting these cultural relics. These issues have troubled relics protectors for a long time. In this study, the authors chose a representative cave in the Mogao Grottoes and, by completely sealing the cave to make a closed system, measured the water vapor from the surrounding rock. This was accomplished by installing a condensation–dehumidification temperature–humidity control system for the collection of water vapor. The results show that there is continuous evaporation from the deep surrounding rock into the cave. The daily evaporation capacity is determined to be 1.02 g/(d?m2). The water sources and driving forces of water movement were further analyzed according to the character of the water evaporation and by monitoring the temperature and humidity of the surrounding rock. It was found that the water vapor in the cave derives from phreatic water. Moreover, the yearly fluctuation of temperature in the surrounding rock and geothermal forces are the basic powers responsible for driving phreatic evaporation. Under the action of the yearly temperature fluctuations, decomposition and combination of bound water acts as a 'pump' that drives phreatic water migration and evaporation. When the temperature rises, bound water decomposes and evaporates; and when it falls, the rock absorbs moisture. This causes the phreatic water to move from deep regions to shallow ones. Determining the source and dynamic foundation of the water provides a firm scientific basis for protecting the valuable cultural relics in the caves. | HongShou LI WanFu WANG HongTao ZHAN Fei QIU QingLin GUO GuoBin ZHANG | 2015 | Journal of Arid Land2015，7，1： | 10 |
| 2 | Performance comparison and parametric study on spiral groove gas film face seals显示文摘Several spiral groove gas film face seals (SGFS) with different layouts are compared quantitatively to analyze their merits and faults and application behaviors. In addition, a parametric study on downstream mode SGFS is conducted to determine its optimal parameters under certain working conditions. In the computation of gas film pressure on the face, finite element method (FEM) is applied to adapt to complicated geometrical boundary. | LIU Yuchuan, SHEN Xinmin, XU Wanfu & WANG ZhiliState Key Laboratory of Tribology, Tsinghua University, Beijing 100084, China School of Mechanical Engineering and Automation, Beijing University of Aeronautics and Astronautics, Beijing 100083, China Lubrication Technology Research Center, Shenyang Institute of Technology, Shenyang 110015, China | 2004 | Science China(Physics,Mechanics & Astronomy)2004，47，z1： | 8 |
| 3 | GSPAC water movement in extremely dry area显示文摘Under an extremely arid condition,a PVC greenhouse was built on the top of Mogao Grottoes in gobi area.The results of 235-day constant extraction of condensed water on the greenhouse film and soil water content showed that 2.1 g/(m2·d) groundwater moved up and exported into the soil,and a phreatic water evaporation existed in the extreme dry area where the groundwater is buried deeper than 200 m.After a prolonged export,the soil water content in the greenhouse was not lower but obviously higher than the original control ones.According to the monitored parameters including relative humidity and absolute humidity of soil,and temperature outside and inside the greenhouse,it was found that there is the available condition and mechanism for the upward movement of groundwater,and also it can be sure that the exported water was not from the soil and atmosphere outside the greenhouse.Phreatic water,an important source for soil water,interacts with atmosphere moisture via soil respiration.Soil salinity also has important effects on soil water movement and spatial-temporal heterogeneity.The extremely dry climate,terrestrial heat and change of upper soil temperature are the fundamental driving forces of water transportation and phreatic water evaporation in the Groundwater-Soil-Plant-Atmosphere Continuum(GSPAC) system. | HongShou Ll WanFu WANG GuoBin ZHANG ZhengMo ZHANG XiaoWei WANG | 2011 | Journal of Arid Land2011，3，2： | 4 |
| 4 | Government integrity and corporate investment efficiency显示文摘We explore the relation between government integrity and firms' investment efficiency in the context of China's deepening reforms and its strengthening the social credit system. We find that government integrity is positively associated with the investment efficiency of listed companies in China. Government integrity is negatively related to corporate underinvestment, but insignificantly related to corporate overinvestment. Higher government integrity reduces underinvestment in non-state-owned firms, but this relation is not significant in state-owned firms. Furthermore, we find that the negative relation between government integrity and underinvestment is only significant for firms in industries that receive supportive government policies. This study enriches research on corporate investment by adopting the perspective of government integrity, and supplements the literature on government integrity and its economic consequences. Our study also provides micro-level empirical evidence that strengthening government integrity will promote the economic transformation of China. | Jing Du Wanfu Li Bin Lin Yu Wang | 2018 | China Journal of Accounting Research2018，，3： | 2 |
| 5 | Overall efficiency of a V-shaped nylon net fence in preventing sand damage to the Mogao Grottoes显示文摘A V-shaped nylon net fence installed in 1990 on top of the Mogao Grottoes is shown to be effectively resisting aeolian sand damage to the grottoes.The structure guides and causes deposition of sand from westerly wind(the primary hard wind),but to some extent hinders the inverse function of easterly wind carrying sand away from the grottoes toward Mount Mingsha.The gobi side by the fence experiences higher wind speed,so that on which are easily formed undercutting pits,and the deposited sands on it generally form double-peak structures due to abundant sand sources.If the earth surface characteristics in gobi areas by both sides of the fence are quite varied,the erosion and deposition features of the accumulating sand section are similar in different seasons;however,if the earth surface characteristics are similar,the features become irregular in different seasons.Sand depositions with long slope feet are formed along the south and north sides of V-shaped nylon net fence.Disrupted by strong westerly wind and northwesterly wind,sand accumulations by north of the fence are in form of single peaks.Although the operation duration of the V-shaped nylon net fence has exceeded its design life(10 years),our observations indicate that it is still effective in reducing wind-driven sand damages to the Mogao Grottoes,so it should not be withdrawn. | GuoShuai Li JianJun Qu WanFu Wang Wei Yang | 2012 | Research in Cold and Arid Regions2012，4，2： | 2 |
| 6 | Polarization-sensitive and wide-spectrum photovoltaic detector based on quasi-1D ZrGeTe_(4)nanoribbon显示文摘Low-dimensional semiconductors with in-plane anisotropy and narrow bandgap have been extensively applied to polarized detection in the near-infrared(NIR)region.However,the narrow bandgap can cause noise owing to the high dark current in photodetectors.This article reports quasi-1D ZrGeTe_(4)nanoribbonbased photodetectors with low dark current and broadband polarization detection.The photodetector was fabricated by evaporating 50-nm-thick Au electrodes on a ZrGeTe_(4)nanoribbon.Benefiting from the photovoltaic characteristics in the ZrGeTe_(4)nanoribbon and Au electrodes,these photodetectors can operate without bias voltage,with decreased dark current,and improved device performance.Furthermore,the quasi-1D ZrGeTe_(4)nanoribbon-based photodetectors demonstrate a polarization sensitivity in a broadband from visible(VIS)to the NIR region,such as a high photoresponsivity of 625.65 mA W1,large external quantum efficiency of 145.9%at 532 nm,and photocurrent anisotropy ratio of 2.04 at 1064 nm.They exhibit a novel perpendicular optical reversal of 90in polarization-sensitive photodetection,angle-resolved absorption spectra,and azimuth-dependent reflectance difference microscopy(ADRDM)from VIS to the NIR region,as opposed to other nanoribbon-based polarization-sensitive photodetectors.This work paves the way for utilizing photovoltaic photodetectors based on low-dimensional materials for broad-spectrum polarized photodetection. | Ruixue Bai Tao Xiong Jinshu Zhou Yue-Yang Liu Wanfu Shen Chunguang Hu Faguang Yan Kaiyou Wang Dahai Wei Jingbo Li Juehan Yang Zhongming Wei | 2022 | InfoMat2022，4，3： | 2 |

| 15 | Effect of ring baffle configuration in a self-priming venturi scrubber using CFD simulations显示文摘This study uses computational fluid dynamics to survey the gas‒liquid flow hydrodynamics of a self-priming venturi scrubber with and without ring baffles.Based on the simulation results,we explore how the structure and configuration parameters such as baffle height,opening-area ratio,and baffle thickness affect the injection flow rate and the homogeneity of the gas‒liquid mixture.In addition,we report the best structure and configuration parameters for the ring baffle.The best position for the ring baffle is at nearly 7/16 of the length of the diffuser above the throat.Having the baffle too near the throat causes large pressure loss,decreasing the injection flow rate.The decrease in opening-area ratio leads to a lower injection flow rate and a more homogeneous gas‒liquid mixture.The optimal value depends on the requirement of the injection flow rate.For the baffle thickness,5 mm is recommended;an overly thick baffle decreases the homogeneity of the gas‒liquid mixture near the throat.All structure parameters and configuration parameters must satisfy the requirement imposed by the injection flow rate and scrubbing efficiency. | Shuai Yang Xiangdi Zhao Wanfu Sun Jiwu Yuan Zheng Wang | 2019 | Particuology2019，17，6： | 1 |
| 16 | Concentrations,sources,and influential factors of water-soluble ions of atmospheric particles in Dunhuang Mogao Grottoes,a world heritage site in China显示文摘Atmospheric particle pollution is one of the major factors leading to degradation of ancient wall paintings,particularly heritage sites in arid and semi-arid regions.However,current systematic research on the changes,sources,and influential factors of atmospheric particulate matter and its water-soluble ion concentrations is not sufficient.Thus,the major water-soluble ion concentrations,sources,and influential factors of atmospheric particles PM_(2.5) and PM_(10)(particulate matter with an aerodynamic equivalent diameter≤2.5 and 10.0μm,respectively,in ambient air)were collected from Cave 16 and its ambient exterior environment in the Dunhuang Mogao Grottoes,China,between April 2015 and March 2016.Results showed that the concentrations of PM_(2.5) and PM_(10) inside and outside the cave were the highest in March 2016 and the lowest in December 2015.The higher particle concentration from March to May was related to the frequent occurrence of sand and dust events,and the lower particle concentration from June to September was associated with good diffusion conditions,increased precipitation,and an established cave shelterbelt.The concentration of particulate matter inside the cave was affected by the concentration of particles in the air outside the cave.Ca2+,NH+4,Na+,Cl-,and SO2-4were the main components of the total ions of PM_(2.5) and PM_(10) both inside and outside the cave.The total ions inside the cave were frequently affected by the disturbance of tourists'activities during the peak tourist season from May to August.Under the influence of dust,the total concentrations of Cl-,SO2-4,Na+,NH+4,and Ca2+in particles of different sizes inside and outside the cave increased,and the concentrations of Cl-,SO2-4,Na+,and Ca2+decreased during precipitation period.Backward air mass trajectory analysis suggested that the pollutants were mainly from Xinjiang,China.The pollutant sources of air particulates are straw burning,secondary pollution sources,soil dust,dry spring rivers,and tourist activities. | YANG Xiaoju WU Fasi XU Ruihong LI Na ZHANG Zhengmo XUE Ping WANG Wanfu ZHAO Xueyong | 2022 | Journal of Arid Land2022，14，12： | 1 |
