1Review on thermal performance of phase change energy storage building envelope显示文摘Improving the thermal performance of building envelope is an important way to save building energy consumption. The phase change energy storage building envelope is helpful to effective use of re-newable energy, reducing building operational energy consumption, increasing building thermal com-fort, and reducing environment pollution and greenhouse gas emission. This paper presents the con-cept of ideal energy-saving building envelope, which is used to guide the building envelope material selection and thermal performance design. This paper reviews some available researches on phase change building material and phase change energy storage building envelope. At last, this paper pre-sents some current problems needed further research.WANG Xin ZHANG YinPing XIAO Wei ZENG RuoLang ZHANG QunLi DI HongFa 2009Chinese Science Bulletin2009,54,6:19
2An impact angle constraint integral sliding mode guidance law for maneuvering targets interception显示文摘An integral sliding mode guidance law(ISMGL)combined with the advantages of the integral sliding mode control(SMC)method is designed to address maneuvering target interception problems with impact angle constraints.The relative motion equation of the missile and the target considering the impact angle constraint is established in the longitudinal plane,and an integral sliding mode surface is constructed.The proposed guidance law resolves the existence of a steady-state error problem in the traditional SMC.Such a guidance law ensures that the missile hits the target with an ideal impact angle in finite time and the missile is kept highly robust throughout the interception process.By adopting the dynamic surface control method,the ISMGL is designed considering the impact angle constraints and the autopilot dynamic characteristics.According to the Lyapunov stability theorem,all states of the closed-loop system are finally proven to be uniformly bounded.Simulation results are compared with the general sliding mode guidance law and the trajectory shaping guidance law,and the findings verify the effectiveness and superiority of the ISMGL.ZHANG Wenjie FU Shengnan LI Wei XIA Qunli 2020Journal of Systems Engineering and Electronics2020,31,1:10

4DeST 3.0:A new-generation building performance simulation platform显示文摘Buildings contribute to almost 30%of total energy consumption worldwide.Developing building energy modeling programs is of great significance for lifecycle building performance assessment and optimization.Advances in novel building technologies,the requirements of high-performance computation,and the demands for multi-objective models have brought new challenges for building energy modeling software and platforms.To meet the increasing simulation demands,DeST 3.0,a new-generation building performance simulation platform,was developed and released.The structure of DeST 3.0 incorporates four simulation engines,including building analysis and simulation(BAS)engine,HVAC system engine,combined plant simulation(CPS)engine,and energy system(ES)engine,connected by air loop and water loop balancing iterations.DeST 3.0 offers numerous new simulation features,such as advanced simulation modules for building envelopes,occupant behavior and energy systems,cross-platform and compatible simulation kernel,FMI/FMU-based co-simulation functionalities,and high-performance parallel simulation architecture.DeST 3.0 has been thoroughly evaluated and validated using code verification,inter-program comparison,and case-study calibration.DeST 3.0 has been applied in various aspects throughout the building lifecycle,supporting building design,operation,retrofit analysis,code appliance,technology adaptability evaluation as well as research and education.The new generation building simulation platform DeST 3.0 provides an efficient tool and comprehensive simulation platform for lifecycle building performance analysis and optimization.Da Yan Xin Zhou Jingjing An Xuyuan Kang Fan Bu Youming Chen Yiqun Pan Yan Gao Qunli Zhang Hui Zhou Kuining Qiu Jing Liu Yan Liu Honglian Li Lei Zhang Hong Dong Lixin Sun Song Pan Xiang Zhou Zhe Tian Wenjie Zhang Ruhong Wu Hongsan Sun Yu Huang Xiaohong Su Yongwei Zhang Rui Shen Diankun Chen Guangyuan Wei Yixing Chen Jinqing Peng 2022Building Simulation2022,15,11:5
5Multiconstraint adaptive three-dimensional guidance law using convex optimization显示文摘The traditional guidance law only guarantees the accuracy of attacking a target. However, the look angle and acceleration constraints are indispensable in applications. A new adaptive three-dimensional proportional navigation(PN) guidance law is proposed based on convex optimization. Decomposition of the three-dimensional space is carried out to establish threedimensional kinematic engagements. The constraints and the performance index are disposed by using the convex optimization method. PN guidance gains can be obtained by solving the optimization problem. This solution is more rapid and programmatic than the traditional method and provides a foundation for future online guidance methods, which is of great value for engineering applications.FU Shengnan LIU Xiaodong ZHANG Wenjie XIA Qunli 2020Journal of Systems Engineering and Electronics2020,31,4:3

18Practical Performance of Passive Thermal Catalysis for Indoor Formaldehyde显示文摘The purpose of this study is to investigate the practical performance of passive thermal catalysis for indoor formaldehyde. A heating plate coated with noble metal catalyst Pt/TiO_2 was made to simulate the radiators with a passive thermal catalysis function. The formaldehyde degradation rate in the presence of the simulated radiator was measured in a stainless-steel chamber under controlled temperature and compared with that in the presence of catalyst powder. The influence of temperature and the concentration of formaldehyde on the degradation performance was measured thoroughly and fitted in the polynomial form. It was found that the degradation capability of the coated catalyst dropped from that of the catalyst power, and the degradation capability trends of both materials in various temperatures were different. The clean air delivery rate(CADR) was found to be merely the function of temperature and irrelevant to indoor formaldehyde concentration in the investigated range.Ge Zhang Yan Li Jiao Bai Qunli Zhang Jing Liu 2019Journal of Harbin Institute of Technology(New Series)2019,26,2:1

20Clinical effect of Sidong Wubu method in treatment of closed fracture of upper limbs显示文摘OBJECTIVE:To objectively evaluate the clinically curative effect of sidong wubu method on closed fracture of upper limbs.METHODS:A single-blind randomized controlled trial was used to divide 654 patients with closed fracture of upper limbs at early stage into two groups.298 patients in the surgical group were treated with open reduction and internal fixation and 356 patients in the treatment group with sidong wubu method for 6 months as a course of treatment.RESULTS:As for short-term curative effect(after 6 courses of treatment),the total effective rate was 97.7% in the treatment group and 92.9% in the control group,and the excellent and good rate was 83.7% and 76.5% respectively.Fracture-healing time,treatment cost,function-recovering time,scores of symptoms and signs obviously declined in both groups with remarkable difference between the two groups.As to long-term curative effect(after follow-up visit for one year to 5 years and 2 months),there was still noticeable difference(χ 2 = 7.536,P<0.05) in total curative effect and in excellent and good rate between the two groups.CONCLUSION:With low cost,short treatment course,good function and other advantages,sidong wubu method can be first used to treat closed fracture of upper limbs.Puwei Yuan Deyu Liu Qiang Zan Yangquan Hao Qunli Dou Genyin Zhang Haiguang Yuan 2012Journal of Traditional Chinese Medicine2012,32,3:1
