| 1 | A review of structures,verification,and calibration technologies of space robotic systems for on-orbit servicing显示文摘Recently,with the rapid development of aerospace technology,an increasing number of spacecraft is being launched into space.Additionally,the demands for on-orbit servicing(OOS)missions are rapidly increasing.Space robotics is one of the most promising approaches for various OOS missions;thus,research on space robotics technologies for OOS has attracted increased attention from space agencies and universities worldwide.In this paper,we review the structures,ground verification,and onorbit kinematics calibration technologies of space robotic systems for OOS.First,we systematically summarize the development of space robotic systems and OOS programs based on space robotics.Then,according to the structures and applications,these systems are divided into three categories:large space manipulators,humanoid space robots,and small space manipulators.According to the capture mechanisms adopted,the end-effectors are systematically analyzed.Furthermore,the ground verification facilities used to simulate a microgravity environment are summarized and compared.Additionally,the on-orbit kinematics calibration technologies are discussed and analyzed compared with the kinematics calibration technologies of industrial manipulators with regard to four aspects.Finally,the development trends of the structures,verification,and calibration technologies are discussed to extend this review work. | DING XiLun WANG YeCong WANG YaoBing XU Kun | 2021 | Science China(Technological Sciences)2021，64，3： | 14 |
| 2 | Review of the biological and engineering aspects of algae to fuels approach显示文摘Current biofuel production relies on limited arable lands on the earth,and is impossible to meet the biofuel demands.Oil producing algae are alternative biofuel feedstock with potential to meet the world’s ambitious goal to replace fossil fuels.This review provides an overview of the biological and engineering aspects in the production and processing technologies and recent advances in research and development in the algae to fuels approach.The article covers biology,selection and genetic modification of algae species and strains,production systems design,culture media and light management,harvest and dewatering,downstream processing,and environment and economic assessment.Despite the many advances made over several decades,commercialization of algal fuels remains challenging chiefly because of the techno-economic constraints.Technological breakthroughs in all major aspects must take place before commercial production of algal fuels becomes economically viable. | Paul Chen Min Min Yifeng Chen Liang Wang Yecong Li Qin Chen Chenguang Wang Yiqin Wan Xiaoquan Wang Yanling Cheng Shaobo Deng Kevin Hennessy Xiangyang Lin Yuhuan Liu Yingkuan Wang Blanca Martinez Roger Ruan | 2009 | International Journal of Agricultural and Biological Engineering2009，2，4： | 9 |

| 9 | 模拟自然光周期下外源性CO_2对城市污水藻类生长和污水处理的影响(摘选)显示文摘探讨了不同光照强度和模拟自然光周期条件下,高浓度生物污水中外源CO2对小球藻(Chlorella kessleri)生物量累积和污水中养分去除的影响。研究结果表明,在所有光强处理情况下,模拟光周期和施加CO2使得Chlorella kessleri能容易地适应反应器中的废水浓度。CO2浓度和光强显著影响藻类生长和污水中养分去除。藻类生长的最适CO2浓度是2.5%。当光强达到一定的下限时,由于光合自养效率显著减少,因此补充CO2的效果最小。同时,由于在第8天时养分耗尽和藻类生物累积量减少,对于持续或分批培养系统的应用体系,应优先选择分批培养的方式。关键词:藻类;城市污水;外源CO2;光照强度;生物量积累; | Megan Ruan Yecong Li Yanling Cheng | 2013 | 农业工程2013，3，1： | 1 |

| 11 | Simulation of thermal and humid environment of rural residence envelope inner surface during the plum rains season in Changsha China显示文摘The Plum Rains Season(PRS)has the typical characteristics of outdoor air temperature dramatic changes and high air humidity in the hot summer and cold winter region in China.Even if the indoor heat source and moisture production is constant,when the outdoor air temperature rises rapidly during high air humidity PRS,the build-ing envelope temperature heats up much more slower than the indoor air temperature and therefore the wall surface temperature is lower than the indoor air dewpoint which leads to condensation phenomenon,resulting in deterioration of insulation performance,mouldy walls,deterioration of indoor air quality.At present,there is a lack of research on the factors affecting condensation in rural residence during PRS.This paper evaluates the impact of occupants’habit of window opening modes and building construction parameters on the building envelope surface condensation in Changsha during PRS.Using Designer’Simulation Toolkit(DeST)simulated and analysed the impact of key parameters such as window-to-wall ratio,exterior wall reflectivity,window opening mode(open/close),and external wall insulation on the building indoor thermal and humid environment.The condensation risk X is proposed to evaluate the condensation possibility on the building envelope’s inner sur-face.The results show that from the perspective of anti-condensation:The rural residential building in Changsha should balance the window-wall ratio against better natural lighting;Keeping windows closed during PRS can effectively alleviate the condensation problem while the insulation in the external wall layer could aggravate the condensation. | He Yecong Deng Qi Zhang Xiaofeng Liu Huaican | 2023 | Energy and Built Environment2023，4，2： | 0 |
| 12 | Uniformity and energy evaluation of equal cross-section ventilation system(ECVS)for long tunnel in underground buildings显示文摘Uniform ventilation is important for the safety of long tunnel in underground buildings,it is difficult to install the large size air duct to ensure the centerline of each cross-section of the traditional variable cross-section ventila-tion system(VCVS)superimposed on the same horizontal axis,which is significant to the ventilation uniformity,energy consumption and installation convenience of the VCVS.On the contrary,each cross-section of the Equal Cross-section Ventilation System(ECVS)has the same horizontal axis,therefore,it is more convenient to manu-facture and install the large size air duct in the underground long tunnel and achieve uniform ventilation.This study proposes an ECVS,using computational fluid dynamics(CFD)numerical simulation analyzed the influences of main duct velocity,aspect ratio,and outlet numbers on uniformity and energy consumption per unit air vol-ume(ECPV).It revealed that when each ventilation equalizer’s valve Angle��is given,uniformity of air supply decreases slightly with an increase in the inlet velocity.When the air supply main duct aspect ratio increases,the outlet velocity standard deviation range is from 0.22 to 0.34.When outlet numbers N=7~12 and��are constant,air supply uniformity and resistance coefficient��also decrease with the decrease of outlet numbers.The outlet number has a significant influence on the uniformity of system air supply,main duct velocity,and aspect ratio are relatively small.ECPV is positively correlated with the main duct velocity and outlet number,and is negatively correlated with aspect ratio. | Qi Deng Huaican Liu Yecong He Tengjin Huang Huan Zhou Ying Bao | 2022 | Energy and Built Environment2022，3，1： | 0 |
