| 1 | An adaptive scaled boundary finite element method by subdividing subdomains for elastodynamic problems显示文摘The scaled boundary finite element method(SBFEM) is a semi-analytical numerical method,which models an analysis domain by a small number of large-sized subdomains and discretises subdomain boundaries only.In a subdomain,all fields of state variables including displacement,stress,velocity and acceleration are semi-analytical,and the kinetic energy,strain energy and energy error are all integrated semi-analytically.These advantages are taken in this study to develop a posteriori h-hierarchical adaptive SBFEM for transient elastodynamic problems using a mesh refinement procedure which subdivides subdomains.Because only a small number of subdomains are subdivided,mesh refinement is very simple and efficient,and mesh mapping to transfer state variables from an old mesh to a new one is also very simple but accurate.Two 2D examples with stress wave propagation were modelled.The results show that the developed method is capable of capturing propagation of steep stress regions and calculating accurate dynamic responses,using only a fraction of degrees of freedom required by adaptive finite element method. | ZHANG ZiHua 1,2,YANG ZhenJun 2,LIU GuoHua 1 & HU YunJin 1 1 College of Civil Engineering and Architecture,Zhejiang University,Hangzhou 310058,China 2 School of Engineering,University of Liverpool,L69 3GQ,UK | 2011 | Science China(Technological Sciences)2011，54，S1： | 4 |
| 2 | Earthworms in soil ecology and organic waste management显示文摘Earthworms are important members of the soil macrofauna.Since C.Darwin(1881)described the important function of earthworms in pedogenesis and in maintenance of soil fertility,there has been continual interest in studying earthworm biology and ecology.Most of the attention in such studies is on earthworm functions in soil nutrient recycling.However,with increasing concerns about the environment,studies using earthworms to mediate organic waste treatment and as an indicator of soil pollution and remediation strategies have grown rapidly in recent years. | Yinsheng LI Zhenjun SUN Feng HU Kevin R.BUTT Joann K.WHALEN | 2021 | Pedosphere2021，31，3： | 1 |
| 3 | Room-Temperature Assembled MXene-Based Aerogels for High Mass-Loading Sodium-Ion Storage显示文摘Low-temperature assembly of MXene nanosheets into three-dimensional(3D) robust aerogels addresses the crucial stability concern of the nano-building blocks during the fabrication process,which is of key importance for transforming the fascinating properties at the nanoscale into the macroscopic scale for practical applications.Herein,suitable cross-linking agents(amino-propyltriethoxysilane,Mn^(2+),Fe^(2+),Zn^(2+),and Co^(2+)) as interfacial mediators to engineer the interlayer interactions are reported to realize the graphene oxide(GO)-assisted assembly of Ti_(3)C_(2)T_(x) MXene aerogel at room temperature.This elaborate aerogel construction not only suppresses the oxidation degradation of Ti_(3)C_(2)T_(x) but also generates porous aerogels with a high Ti_(3)C_(2)T_(x) content(87 wt%) and robustness,thereby guaranteeing the functional accessibility of Ti_(3)C_(2)T_(x) nanosheets and operational reliability as integrated functional materials.In combination with a further sulfur modification,the Ti_(3)C_(2)T_(x) aerogel electrode shows promising electrochemical performances as the freestanding anode for sodium-ion storage.Even at an ultrahigh loading mass of 12.3 mg cm^(-2),a pronounced areal capacity of 1.26 mAh cm^(-2) at a current density of 0.1 A g^(-1) has been achieved,which is of practical significance.This work conceptually suggests a new way to exert the utmost surface functionalities of MXenes in 3D monolithic form and can be an inspiring scaffold to promote the application of MXenes in different areas. | Fei Song Jian Hu Guohao Li Jie Wang Shuijiao Chen Xiuqiang Xie Zhenjun Wu Nan Zhang | 2022 | Nano-Micro Letters2022，14，2： | 1 |

| 13 | Study on Pinus elliottii Plantations in Pengchang Forest Farm of Jingmen City显示文摘[Objectives]This study was conducted to improve the ecological and economic benefits of Pinus elliottii plantations in Pengchang Forest Farm, Jingmen City. [Methods] P. elliottii plantations in Pengchang Forest Farm in Jingmen City were selected as the research object, and the appearance and quantitative characteristics of P. elliottii community were studied and analyzed by a sampling method. [Results] Phanerophytes were the most in the P. elliottii community, accounting for 50%. In the community, except P. elliottii, the importance values of native plants were higher. The order of species diversity of P. elliottii community in Pengchang Forest Farm was herb layer, tree layer and shrub layer. The stress resistance of the community was weak, and strong intraspecific competition existed in P. elliottii. It is recommended to thin P. elliottii trees with insufficient lighting, poor growth potential and severely damaged tree body, and interplant Phoebe zhennan after thinning the P. elliottii plantations, so as to create a coniferous and broad-leaved evergreen mixed forest. [Conclusions] This study provides scientific support for thinning, tending, and forest management of P. elliottii plantations. | Pengfei XU Maochang LIANG Zhenjun WU Lidan FANG Yongjun FEI Die HU | 2022 | Agricultural Biotechnology2022，11，5： | 0 |
| 14 | HIRFL-CSR Vacuum Baking-out System显示文摘In order to meet the requirements of the beam storage time in HIRFL-CSR, the average vacuum degree in this system must be better than 6×10-9 Pa, so the system should be baked to about 250℃ on the line after being exposed to atmosphere and be well controlled. In this paper, determination of baking temperature, the thermal sensors, thermal insulators and heater jackets, baking-out process and control and test results on CSRm prototype are introduced. | Zhang Junhui, Yang Xiaotian, Hu Zhenjun, Hou Shengjun, Zhang Xiping, Meng Jun and Niu Zhiwei | 2002 | 近代物理研究所和兰州重离子加速器实验室年报:英文版2002，，1： | 0 |

The bake-out temperature isincreased 30 ?C per one hour.(2) Start the ion pump, at the same time, bake out the testing chamber at 180 ?C for 10 h continuously. Theion pump would work normally after degassing for 30 min. | Luo Cheng Meng Jun Chai Zhen Xie Wenjun Hu Zhenjun | 2014 | IMP & HIRFL Annual Report2014，，1： | 0 |
| 16 | 6-39 Design of NEG Coating Equipment for Dipole Vacuum Chamber显示文摘A novel technique is developed to turn the gas-load of the slender vacuum pipes into NEG (non-evaporationgetters) pump[1]. In the technique, the NEG films are grown by DC (Direct-Current) reactive magnetron sputteringon the inner wall of the pipes. There are many vacuum-related characteristics for NEG films, including the secondelectron yield (SEY), photon stimulated desorption (PSD) and pumping performance. Because the lowest activationtemperature is only about 180?C, TiZrV alloys getters are chosenasNEG coating[2]. This technique will be widelyused for electron, proton and heavy ion accelerators in the future. | Cheng Jinze Meng Jun Ma Xiangli Hu Zhenjun | 2014 | IMP & HIRFL Annual Report2014，，1： | 0 |
| 17 | Progress of HIRFL-CSR Vacuum System显示文摘In 2005, the installation of whole vacuum system of HIRFL-CSR was finished and the ideal pressures have been obtained. During the beam commissioning, the vacuum system of CSRm's injection beam line keeps a good condition in most of the cases. But at one time, the beam bumped against a glass view window in a 60°dipole chamber which was designed for alignment (Fig. 1). The fast valve closed when the pressure rose.

| 18 | Calculation of Differential Vacuum System of HIRFL-TR2显示文摘In order to carry on research work in the field of super-heavy nuclei, our institute plans to build up a new system in HIRFL-TR2 terminal. The working pressure in target chamber is 100 Pa and the working pressure in beam line is lower than 10-5 Pa. It is almost impossible to achieve this transition through a single tube because the distance between target chamber and beam line is only 2 m. So it is necessary for us to design a set of multistage differential vacuum system. The principle of differential vacuum system is showed as Fig. 1. | Meng Jun,Yang Xiaotian, Zhang Suping, Hou Shengjun and Hu Zhenjun | 2005 | 近代物理研究所和兰州重离子加速器实验室年报:英文版2005，，1： | 0 |
