| 2 | OPEN ARCHITECTURE CNC SYSTEM HITCNC AND KEY TECHNOLOGY显示文摘Aiming at the characteristics of modularity and reconfigurable in open architecture com-puter numerical control (CNC) system,the open architecture CNC system,Harbin Institute of Tech-nology computer numerical control (HITCNC),is researched and manufactured based on the interface standards. The system’s external interfaces are coincident with the corresponding international stan-dards,and the internal interfaces follow the open modular architecture controller (OMAC) agreement. In the research and manufacturing process,object-oriented technology is used to ensure the openness of the HITCNC,and static programming is applied in the CNC system according to the idea of modu-larization disassembly. The HITCNC also actualizes real-time and unreal-time modules adopting real-time dynamical linked library (RTDLL) and component object model (COM). Finite state ma-chine (FSM) is adopted to do dynamically modeling of HITCNC. The complete separation between the software and the hardware is achieved in the HITCNC by applying the SoftSERCANS technique. The application of the above key techniques decreases the programming workload greatly,and uses software programs replacing hardware functions,which offers plenty technique ensures for the open-ness of HITCNC. Finally,based on the HITCNC,a three-dimensional milling system is established. On the system,series experiments are done to validate the expandability and interchangeability of HITCNC. The results of the experiments show that the established open architecture CNC system HITCNC is correct and feasible,and has good openness. | WANG Yongzhang LIU Tao FU Hongya HAN Zhenyu | 2007 | Chinese Journal of Mechanical Engineering2007，20，2： | 4 |
| 3 | Effect of Friction Reclaimed Materials of Waste Brake-shoe on Basic Performance of Mortar显示文摘Discarded train brake shoes mainly consist of steel-backed friction material. To be better reutilized, its essential features and its interaction in cement-based material need to be studied. Consequently, particle size analysis, SEM, IR and TGA were used to investigate two types of waste brake shoes, i e, mechanical grinding friction reclaimed material of waste brake-shoe(G-FRMWBS) and pyrolysis-friction reclaimed materials of waste brake-shoe(P-FRMWBS). The latter exhibited less organic content, larger range of particle size distribution and smaller medium particle diameter. Both types contained inorganic particles of spherical and irregular shapes, striped with steel fiber. Upon isometric substituting fine aggregates, G-FRMWBS lifted the strength of mortar effectively that was increased by 16.6% and 17.5% when the replacing rate was 5%; the value went up to 19.2% and 19.2% when the replacing rate was 10%. Moreover, inclusion of FRMWBS enhanced the chloride penetration resistance, and optimized the pore characteristic and ITZ(interfacial transition zone) as well. | 王彩辉 HUANG Dongjie FU Hua WU Hongya QIN Guoqiang SUN Guowen GUO Na | 2017 | Journal of Wuhan University of Technology(Materials Science)2017，32，3： | 3 |
| 4 | Allogeneic hematopoietic stem cell transplantation for patients with acute leukemia显示文摘Objective: The purposes of this study were to assess the efficacy of allogeneic hematopoietic stem cell transplantation (HSCT) for acute leukemia (AL) and analyze the factors affecting the prognosis of these patients. Methods: The clinical and follow-up data of 93 AL patients (median age, 30 years) undergoing allogeneic HSCT in Xiangya Hospital over the past 12 years were collected, and the potential factors affecting the efficacy and prognosis of allogeneic HSCT patients were determined. Results: Hematopoietic reconstitution was achieved in 90 patients. At the last follow-up, the incidences of severe acute graft versus host disease (aGvHD) and extensive chronic GvHD (cGvHD) were 14.0% and 20.0%, the 3-year cumulative incidence of transplantation related mortality (TRM) and relapse rate were 16.8%±6.1% and 21.3%±6.7%, and the estimated 3-year overall survival (OS) and disease-free survival (DFS) of the patients were 64.6%±5.4% and 56.5%±5.5%, respectively. Univariate analysis indicated that age older than 40 years, HLA mismatch, and severe lung infection within the first 100 days after transplantation were risk factors for severe aGvHD, age older than 40 years, HLA mismatch, severe lung infection within the first 100 days after transplantation, and severe aGvHD were risk factors for TRM, high-risk AL and lack of cGvHD were risk factors for relapse (all P<0.05). Survival estimation showed that HLA mismatch, severe lung infection occurring within the first 100 days post-transplantation, high-risk AL severe aGvHD and lack of cGvHD were risk factors associated with poor prognosis (all P<0.05). Further multivariate analyses revealed that severe lung infection within the first 100 days post-transplantation, severe aGvHD and lack of cGvHD were independent risk factors for unfavorable outcomes (all P<0.05). Conclusions: Allogeneic HSCT can improve the DFS of AL patients, and severe lung infection within the first 100 days post-transplantation, severe aGvHD and lack of cGvHD are independent risk factors affecting the prognosis. | Yan Chen Yajing Xu Gan Fu Yi Liu Jie Peng Bin Fu Xiaoyu Yuan Hongya Xin Yan Zhu Qun He Dengshu Wu Yigang Shu Xiaolin Li Xielan Zhao Fangping Chen | 2013 | Chinese Journal of Cancer Research2013，25，4： | 3 |
| 5 | Fractal Design Boosts Extrusion-Based 3D Printing of Bone-Mimicking Radial-Gradient Scaffolds显示文摘Although extrusion-based three-dimensional(EB-3D)printing technique has been widely used in the complex fabrication of bone tissue-engineered scaffolds,a natural bone-like radial-gradient scaffold by this processing method is of huge challenge and still unmet.Inspired by a typical fractal structure of Koch snowflake,for the first time,a fractal-like porous scaffold with a controllable hierarchical gradient in the radial direction is presented via fractal design and then implemented by EB-3D printing.This radial-gradient structure successfully mimics the radially gradual decrease in porosity of natural bone from cancellous bone to cortical bone.First,we create a design-to-fabrication workflow with embedding the graded data on basis of fractal design into digital processing to instruct the extrusion process of fractal-like scaffolds.Further,by a combination of suitable extruded inks,a series of bone-mimicking scaffolds with a 3-iteration fractal-like structure are fabricated to demonstrate their superiority,including radial porosity,mechanical property,and permeability.This study showcases a robust strategy to overcome the limitations of conventional EB-3D printers for the design and fabrication of functionally graded scaffolds,showing great potential in bone tissue engineering. | Huawei Qu Zhenyu Han Zhigang Chen Lan Tang Chongjian Gao Kaizheng Liu Haobo Pan Hongya Fu Changshun Ruan | 2021 | Research2021，，1： | 2 |
| 6 | ADAPTIVE LEARNING CONTROL OF CUTTING PARAMETERS FOR SCULPTURED SURFACE CUTTING BASED ON GENETIC ALGORITHMS AND NEURAL NETWORK显示文摘An adaptive learning control scheme intended to the on-line optimization of sculptured surface cutting process is presented. The scheme uses a back-propagation neural network to learn the relationships between process inputs and process states. The cutting parameters of the process model are optimized through a genetic algorithms(GA). The capacity of the proposed scheme for determining optimum process inputs under a variety of process conditions and optimization strategies is evaluated on the basis of milling of a sculptured surface using a ball-end mill. The experimental results show that the neural network could model the cutting process efficiently, and the cutting conditions such as spindle speed could be regulated for achieving high efficiency and high quality. Therefore the proposed approach can be well applied to the manufacturing of dies and molds. | Fu Hongya Wang Yongzhang Lu Hua Fu Yunzhong Department of Mechanical Engineering, Harbin Institute of Technology, Harbin 150001, ChinaTakaaki Nagao University of Tokyo, Japan | 2002 | Chinese Journal of Mechanical Engineering2002，15，2： | 1 |

| 11 | Effects of Internal Relaxation under Inplane Strain on the Structural,Electronic and Optical Properties of Perovskite BaZrO3显示文摘We present the specific ab-initio calculations that detail the variations of perovskite BaZrO_3 caused by in-plane strain. Specifically, the internal relaxation, which was not captured in the widely used biaxial strain model, was included in a complementary manner to lattice relaxation. Density functional theory as well as a hybrid functional method based on a plane wave basis set was employed to calculate the lattice structure, elastic constants, electronic properties and optical properties of perovskite BaZrO_3. The lattice parameter c exhibited a clear linear dependence on the imposed in-plane strain, but the Poisson's ratio caused by internal relaxation was smaller than the elastic deformation, indicating an 'inelastic' or 'plastic' relaxation manner caused by the introduction of internal relaxation. As a result, the related electronic and optical properties of perovskite BaZrO_3 were also strongly affected by the in-plane strain, which revealed an effective way to adjust the properties of perovskite BaZrO_3 via internal relaxation. | 秦国强 PENG Xiaojun ZHANG Guanglei WU Hongya WANG Caihui YU Gang FU Hua | 2017 | Journal of Wuhan University of Technology(Materials Science)2017，32，2： | 0 |
