2Paleogene-Neogene stratigraphic realm and tectonic-sedimentary evolution of the Qilian Mountains and their surrounding areas显示文摘The Cenozoic uplift of Qilian Mountains is critical to comprehend the uplift and extension of the Tibet Plateau as well as the formation of the first and second steps in China's topography. This study summarized dynamic stratigraphic realm comprehensively on the basis of stratigraphic correlation of different Cenozoic sedimentary basin regions of the Qilian Mountains and adjacent mountains. This facilitated the re-creation of the tectonic-sedimentary evolutionary process of the Qilian Mountains and their surrounding areas. The results indicate that during the Early Paleogene(Paleocene-Eocene), the Qilian Mountains were part of an uplift realm. During the Oligocene, Guide-Xining-Lanzhou-Linxia sag basin at the northern margin of the West Qinling Mountains came into being and was subjected to sedimentation. The Suli Basin located between the North and South Qilian paleo-uplifts began to form and undergo sedimentation. Intracontinental orogenic extrusion and basin detachment occurred at the Qilian Mountains during the Miocene, which caused successive uplifts of various mountains, including the Laji, South Qinghai,Jishi, Liupan, and South Shule Mountains. Until Pliocene, Qilian Mountains uplifted continuously and resulted in the shrink,extinction and being eroded of the basins, and aeolian red clay started to accumulate.YANG LiRong LI JianXing YUE LePing WANG HongLiang GUO HuaiJun ZHU XiaoHui ZHU Tao DU Kai ZHANG Rui ZHANG YunXiang GONG HuJun 2017Science China Earth Sciences2017,60,5:1
3The Related Problems in the Construction of the Rainy Season显示文摘With the continuous development of society and the improvement of people's living standard,the construction scale of construction project is increasing and the construction period also increases.In the construction process,the weather changes are often one of the key factors aff ecting the progress and quality of the project.Rainy season construction is the inevitable problem in the construction process,the rainy season construction facing rain,wind,high temperature and other adverse environmental factors,and can directly endanger the production safety,to the enterprise to bring immeasurable losses,so science reasonable organization of construction,to take security technical measures,and actively respond to the rainy season construction of various dangerous situations,to improve the ability to resist risks,to ensure the safety of production,is of great signifi cance.Based on the theory of construction safety management and the characteristics of rainy season,this paper analyzes and controls according the experience and technical characteristics of engineering construction.To ensure the progress and quality of construction and the safety of construction,the principle of minimizing the loss,put forward the corresponding maintenance measures to enhance the safety of the rainy season construction,to enhance the economic interests of enterprises.Shiyong Zhao Leping Du Xiangdong Chen 2018Insight-Civil Engineering2018,1,1:0
4A Molecular Analysis of Critical Factors for Interface and Size Effects on Heat Conduction in Nanoconfined Water Film显示文摘Heat conduction of nanoconfined liquid may differ from its bulk because of the effects of size,geometry,interface,temperature,etc.In this study,the roles of some critical factors for the heat conduction of nanoconfined water film are systematically analyzed by using the molecular dynamics method.With decreasing thickness,the normal thermal conductivity of nanoconfined water film between two copper plates decreases exponentially,while the thermal resistance,peak of the radial distribution function,and atomistic heat path increase exponentially.The average bond order,radial distribution function,mean squared displacement,and vibrational density of states are calculated to analyze the effects of structure,distribution,molecular diffusion,and vibration of water molecules on heat conduction especially in a region having no oxygen atoms(which is observed by the near-wall density profile).The results show that phonon scattering is dominant for determining the reduced thermal conductivity in this near-wall region.The thermal conductivity ratio of confined water film to bulk water has a roughly linear relationship with the logarithm of the proportion of the near-wall region.Moreover,the high interfacial thermal resistance is positively correlated to the film thickness,but it has a negligible impact on heat conduction.This work provides insights into the contribution of water molecules near the solid/liquid interface to the heat conduction of nanoconfined liquid for process intensification.JIN Lu ZHOU Leping DU Xiaoze 2022Journal of Thermal Science2022,31,4:0
