| 1 | An Efficient and Stable Ionic Liquid System for Synthesis of Ethylene Glycol via Hydrolysis of Ethylene Carbonate显示文摘An ionic liquid system of [Bmim]X/[Bmim]OH(X Cl,BF4,and PF6,) was developed for the hydroly-sis of ethylene carbonate to ethylene glycol. The important parameters,such as the variety of ionic liquids,molar ratio of [Bmim]X to [Bmim]OH,amount of ionic liquid,molar ratio of water to ethylene carbonate,reaction tem-perature,pressure and reaction time,were investigated systematically. Excellent yield(>93%) and high selectivity(99.5%) of ethylene glycol were achieved. Under the optimum reaction conditions,the ionic liquid system could be reused at least five times and the selectivity of ethylene glycol remained higher than 99.5%. | MENG Zhenying SUN Jian WANG Jinquan ZHANG Jianxin FU Zengzeng CHENG Weiguo ZHANG Xiangping | 2010 | Chinese Journal of Chemical Engineering2010，18，6： | 8 |

| 5 | Characterization of PM2.5 Mass Concentration in the Onshore of Sanya, China显示文摘Numbers of real-time data(E-BAM)of PM2.5 were collected in the period from Jan 8th 2012 to Jan 1st 2013 at the laboratory of Tropical Ocean University(Sanya,China).The average mass concentration was 19.7μg/m³.The highest 40.5μg/m³in October compared to the lowest 14.1μg/m³in July.From a seasonal perspective,the average PM2.5 mass concentration in fall and winter are relatively higher than that in both spring and summer.On the basis of satellite map of fire points and backward trajectories of the air masses,we primarily deduced that the PM2.5 in Sanya may be caused by the biomass burning and industrial pollutants from the area of Pearl River Delta of China and the Indo-China peninsula(e.g.Vietnam,Laos). | Ping Wang Chao Han Youzhi Zhao Wenci Ding Zengzeng Li | 2020 | Journal of Atmospheric Science Research2020，3，2： | 0 |
| 6 | Self-adaptive rolling motion for snake robots in unstructured environments based on torque control显示文摘Snake robots have great potential for exploring and operating in challenging unstructured environments,such as rubble,caves,and narrow pipelines.However,due to the complexity and unpredictability of unstructured environments,designing a controller that can achieve adaptive motion is crucial.This paper proposes a self-adaptive torque-based rolling controller for snake robots,enabling compliant motion in unstructured environments.First,a controller is designed to modify the torque of each motor by focusing on the different motion states of the rolling gait.Second,an experimental platform is established for snake robots to verify the effectiveness of the controller.Finally,a series of rolling experiments are conducted using the torque-based rolling controller.In conclusion,the self-adaptive torque-based rolling controller enhances snake robot adaptability and mobility. | Shihao Ma Fatao Qin Shufan Chen Longchuan Li Jianming Wang Zengzeng Wang Shuai Li Xuan Xiao | 2023 | Biomimetic Intelligence & Robotics2023，3，3： | 0 |
