| 1 | Generalized non-linear strength theory and transformed stress space显示文摘Based on the test data of frictional materials and previous research achievements in this field, a generalized non-linear strength theory (GNST) is proposed. It describes non-linear strength properties on the π-plane and the meridian plane using a unified formula, and it includes almost all the present non-linear strength theories, which can be used in just one material. The shape of failure function of the GNST is a smooth curve between the SMP criterion and the Mises criterion on the π-plane, and an exponential curve on the meridian plane. Through the transformed stress space based on the GNST, the combination of the GNST and various constitutive models using p and q as stress parameters can be realized simply and rationally in three-dimensional stress state. | YAO Yangping LU Dechun ZHOU Annan ZOU Bo | 2004 | Science China(Technological Sciences)2004，47，6： | 57 |
| 2 | Real-time rapid prediction of variations of Earth's rotational rate显示文摘Real-time rapid prediction of variations of the Earth's rotational rate is of great scientific and practical importance. However, due to the complicated time-variable characteristics of variations of the Earth's rotational rate (i.e., length of day, LOD), it is usually difficult to obtain satisfactory predictions by con-ventional linear time series analysis methods. This study employs the nonlinear artificial neural net-works (ANN) to predict the LOD variations. The topology of the ANN model is determined by minimizing the root mean square errors (RMSE) of the predictions. Considering the close relationships between the LOD variations and the atmospheric circulation movement, the operational prediction series of axial atmospheric angular momentum (AAM) is incorporated into the ANN model as an additional input in the real-time rapid prediction of LOD variations with 1-5 days ahead. The results show that the LOD pre-diction is significantly improved after introducing the operational prediction series of AAM into the ANN model. | WANG QiJie LIAO DeChun ZHOU YongHong | 2008 | Chinese Science Bulletin2008，53，7： | 8 |
| 3 | Lateral epitaxial growth of two-dimensional heterostructure linked by gold adatoms显示文摘Lateral two-dimensional(2D)heterostructures have great potential for device engineering at the atomistic scale.Their production is hindered by difficulties in obtaining atomically sharp interface free from intermixture.Here we report the continuous construction of a lateral heterostructure using blue phosphorene and tetrafluoro-tetracyanoquinodimethane(F_(4)TCNQ)as the building blocks.The lateral heterostructure is achieved by linking the semiconducting F_(4)TCNQ-Au metal organic framework and the metallic blue phosphorene-Au network via Au adatoms.The structural and electronic properties of the heterostructure have been investigated by means of scanning tunneling microscopy and spectroscopy(STM/S),complemented by density functional theory(DFT)calculations,demonstrating a structurally and electrically abrupt interface.Our approach offers the possibility of high flexibility and control that can be extended to other metal-organic species and 2D materials,establishing a foundation for the development of atomically thin in-plane superlattice and devices. | Nan Si Tao Shen Xinyi Liu Dechun Zhou Qingmin Ji Wei Liu Shuang Li Tianchao Niu | 2021 | Nano Research2021，14，3： | 2 |
| 4 | Overexpression of OsSPL9 enhances accumulation of Cu in rice grain and improves its digestibility and metabolism显示文摘Copper(Cu)is an essential trace mineral element for all forms of life,and is an important structural component and co-factor for a variety of metalloenzymes(Pen^a et al.,1999;Bertinato and L'Abbe,2004).In humans,Cu deficiency is not common because of the ubiquitous occurrence of Cu and ease of gastrointestinal absorption(Zidar et al.,1977;Uauy et al.,1998).However,because of the low Cu content in most sources of feed,the use of Cu as a growth promoter to maximize animal production has been well documented in animal feeding(Braude,1945;Lu et al.,2010).Pre- | Mingfeng Tang Chuanshe Zhou Lu Meng Donghai Mao Can Peng Yuxing Zhu Daoyou Huang Zhiliang Tan Caiyan Chen Chengbing Liu Dechun Zhang | 2016 | Journal of Genetics and Genomics2016，43，11： | 2 |
