| 1 | A high-sensitivity MEMS gravimeter with a largedynamic range显示文摘Precise measurement of variations in the local gravitational acceleration is valuable for natural hazard forecasting,prospecting,and geophysical studies.Common issues of the present gravimetry technologies include their high cost,high mass,and large volume,which can potentially be solved by micro-electromechanical-system(MEMS)technology.However,the reported MEMS gravimeter does not have a high sensitivity and a large dynamic range comparable with those of the present commercial gravimeters,lowering its practicability and ruling out worldwide deployment.In this paper,we introduce a more practical MEMS gravimeter that has a higher sensitivity of 8μGal/√Hz and a larger dynamic range of 8000 mGal by using an advanced suspension design and a customized optical displacement transducer.The proposed MEMS gravimeter has performed the co-site earth tides measurement with a commercial superconducting gravimeter GWR iGrav with the results showing a correlation coefficient of 0.91. | Shihao Tang Huafeng Liu Shitao Yan Xiaochao Xu Wenjie Wu Ji Fan Jinquan Liu Chenyuan Hu Liangcheng Tu | 2019 | Microsystems & Nanoengineering2019，5，1： | 2 |

| 4 | Effects of Antifouling Technology Application on Marine Ecological Environment显示文摘Resolving the contradiction between Marine economic development and Marine ecological environment protection has become an unavoidable and sharp problem.The uncontrolled use of Marine antifouling technology will bring uncontrollable and even irreversible damage to the Marine biosphere,which will lead to ecological disaster and threaten the survival of human beings.Therefore,it is an urgent task to find antifouling technology with lower environmental toxicity under the premise of considering economy.More attention should be paid to the long-term impact of mature and new technologies on the Marine ecological environment.This paper introduces the development status of antifouling technology,its influence on Marine ecological environment and puts forward the design strategy of comprehensive biological fouling prevention and control technology. | Liangcheng Liu Ge Wang Junyi Song Bipu Hu | 2022 | Sustainable Marine Structures2022，4，1： | 0 |
| 5 | Apparent Kinetics of 1-Decene Polymerization Catalyzed Using the Ionic Liquid[Bmim]_(x)[C_(2)H_(5)NH_(3)]_(1-x)[Al_(2)Cl_(7)]显示文摘Poly-α-olefin(PAO)synthetic oil,a regular long-chain alkane produced from the catalytic polymerization ofα-olefin,is a high-quality lubricating base oil with huge market potential.In this study,PAO synthesis based on the catalytic polymerization of 1-decene using the ionic liquid(IL)[Bmim]_(x)[C_(2)H_(5)NH_(3)]_(1-x)[Al_(2)Cl_(7)]as the catalyst was studied.Compared with the conventional catalyst[Bmim][Al_(2)Cl_(7)],the obtained PAO product incorporates more trimers and tetramers of 1-decene and contains few double-bond end groups,demonstrating a better catalytic system for PAO-10 production.The apparent polymerization kinetics of 1-decene in this catalytic system were studied based on the 1-decene concentration,catalyst concentration,and reaction temperature.An apparent kinetic equation for PAO formation was determined,providing a promising strategy for PAO production using 1-decene polymerization. | Chen Yingze He Jinxue Wang Ben Pan Shiguang Zhang Di Bai Zhongxiang An Liangcheng Liu Dan Ma Aijing Li Hu Gui Jianzhou | 2023 | China Petroleum Processing & Petrochemical Technology2023，25，4： | 0 |
| 6 | Culture of Eriocheir sinensis Larvae in Ponds in Greenhouse显示文摘A total of 15 pools were selected from a greenhouse, and they were randomly and evenly divided into three groups.In each group, one stocking density of Eriocheir sinensis was arranged. The results showed that after 45-d culture, the crab number per kilogram reached about 300 with survival rate of about 20%; the initial stocking density had significantly effect on the body size of E. sinensis on sell, instead on the survival rate of E. sinensis larvae. Therefore, it is feasible to conduct the culture of E. sinensis larvae in a pool in greenhouse. | Guoliang RUAN Liangcheng HU Hai ZHOU Dawen MA Yabin TANG | 2016 | Agricultural Science & Technology2016，17，3： | 0 |
