| 1 | Simulation of regional land subsidence in the southern Yangtze Delta显示文摘Investigation of the deformation characteristics of individual hydrostratigraphic units is the key to construct a regional land subsidence model. All of 12 hydrostratigraphic units in the study area were discussed throughout. On the basis of the measured data of groundwater level, five kinds of changing patterns of groundwater level were deduced and the relationship between the deformation characteris-tics of aquifer units and the corresponding changing patterns of groundwater level was discussed. The study area is 1.7×104 km2, where the geological condition is complex. The changing patterns of groundwater level the hydrostratigraphic units have experienced vary from site to site and from time to time. Consequently, the deformation characteristics of units are sophisticated. An identical hydros-tratigraphic unit may exhibit different deformation characteristics, such as elasticity, elasto-plasticity, visco-elasticity, and visco-elasto-plasticity, at different sites or during different periods, not to mention the different units. The existing models are difficult to describe the complex visco-elasto-plastic con-stitutive law under the condition of land subsidence. So the Merchant’s model was modified to depict the visco-elasto-plastic behavior of units. Then a three-dimensional flow model with variable parame-ters and a vertical one-dimensional subsidence model were constructed and coupled. The coupled model was applied in simulating land subsidence in the southern Yangtze Delta and a satisfactory re-sult was obtained. The simulation results show that the new coupled model can depict the complex geological conditions and describe the developing process of land subsidence very well in the south-ern Yangtze Delta. The new model can surely be used to predict land subsidence in the future, which is very helpful to taking measurements to control land subsidence. | XUE YuQun WU JiChun ZHANG Yun YE ShuJun SHI XiaoQing WEI ZiXin LI QinFen YU Jun | 2008 | Science China Earth Sciences2008，51，6： | 6 |

| 13 | Brief Analysis on Causes and Current Situations of Desertification: A Case Study of Tongyu County in Jilin Province显示文摘Land desertification is a complex concept which refers to land degradation in the arid region, semi-arid region and sub-humid arid region caused by various factors including climate variability and human activities. It is not only an environmental problem, but also a social and economic one[1]. Land desertification will reduce the biological and economic production potential of the land and even exacerbate the trend of land desertification, leaving serious impact on the economic, social development and national lives of Jilin. In addition, it will result in ecological environment deterioration, microclimate variability, an increase in natural disaster and high frequency of sand blowing. Taking the special geographic area in western Jilin (especially the Tongyu County) as an example, this paper discusses the natural and social factors for the forming of desertification in the microcosmic level, analyzes the current situations and provides reasonable recommendations. | Jing WANG Yuqun SU Changlong XUE | 2013 | Asian Agricultural Research2013，5，4： | 1 |

| 15 | Sea water intrusion and salt water intrusion in the coastal area of Laizhou Bay显示文摘The characteristics, pattern, hydrodynamic and hydrochemical features, and the movement pattern of the salt water-fresh water interface of the sea water intrusion and the salt water intrusion, which occur in the coastal area of Laizhou Bay in Shandong Province, are analysed. The characteristics of the two kinds of intrusion are compared as well. A three-dimensional sea water intrusion model to describe the sea water intrusion with a transitional zone 1.56.0 km wide in the phreatic aquifer and a solute transport model describing the behavior of cations exchange in the process of sea water intrusion are established. | Xue Yuqun Wu Jichun Xie Chunhong Zhang Yongxiang | 1998 | Chinese Science Bulletin1998，43，12： | 0 |
| 16 | Traveling-wave parametric amplifiere-induced qubit dephasing:analysis and mitigation显示文摘The mitigation of dephasing poses a significant challenge toimproving the performance of error-prone superconducting quantum computing systems.Here,the dephasing of a transmon qubit ina dispersive readout regime was investigated by adopting aJosephson traveling-wave parametric amplifier as the preamplifier.Our findings reveal that the potent pump leakage from the preamplifier may lead to severe dephasing.This could be attributed to amixture of measurement-induced dephasing,ac Stark effect,andheating.It is showed that pulse-mode readout is a promising measurement scheme to mitigate qubit dephasing while minimizing theneed for bulky circulators.Our work provides key insights intomitigating decoherence from microwave-pumped preamplifiers,which will be critical for advancing large-scale quantum computers. | Yingshan Zhang Huikai Xu Yu Song Yuqun Xu Shuang Yang Ziyue Hua Shoukuan Zhao Weiyang Liu Guangming Xue Yirong Jin Haifeng Yu | 2023 | Chip2023，2，4： | 0 |
| 17 | Seawater Intrusion in the Longkou-Laizhou Area, Shandong显示文摘The extensive intrusion (covering an area of 83.7-238.3 km^2 and accounting for 18.6-31.5% of the total area of the plain), the presence of a transitional zone 1.5-6.0 km in width, and the interconnection in distribution between the seawater intrusion district and the region lower than the sea level caused by the strong drop of the groundwater level are major characteristics of the seawater intrusion in the study area. Cation exchange played an important role during the formation of chemical composition of the groundwater in the seawater intrusion district. | Xue Yuqun, Xie Chunhong, Wu Jichun, Nanjing University Liu Peimin, Wang Jianji, Jiang Qingbo Office of Water Resources of Longkou City Shi Hongwen and Ning Pihai Office of Water Resources of Laizhou City Liu Linqun | 1993 | Acta Geologica Sinica(English Edition)1993，67，1： | 0 |
| 18 | A Study of Aquifer Thermal Energy Storage:Numerical Simulation of Thermal Storage Experiments in Shanghai显示文摘This paper proposes a 3-D convection-heat dispersion model for a confined aquifer. The governing equation of the model contains not only the traditional convection and conduction terms, but also a heat dispersion term which has often been overlooked in many similar researches. The model is used to describe a series of aquifer thermal energy storage experiments conducted at the Shanghai experimental site, including single-well injection, double-well injection/production and multiple-well injection/prodution tests. The simulated temperatures agree very well with the field data (relative error: 2.8%-4.5%). A detailed description of the model is given, followed by a detailed comparison of simulated and measured temperature distributions. | Xue Yuqun Dept.of Earth Sciences, Nangjing University, Nanjing Xie Chunhong Dept.of Mathematics, Nangjing University, Nanjing and Li Qinfen Shanghai Environmental Geology Center, Shanghai | 1989 | Acta Geologica Sinica(English Edition)1989，63，3： | 0 |
