2Mineral chemistry, P-T-t paths and exhumation processes of mafic granulites in Dinggye, Southern Tibet显示文摘The mafic granulites in Dinggye, as various scale lense-shaped enclaves within the high Himalayan crystalline rock series, occur along mylonitic foliations at the junction between the Southern Tibetan Detachment System (STDS) and the Xainza-Dinggye normal fault system. The main lithological assemblage comprises garnet plagioclase pyroxenite, garnet two-pyroxene granulite, pyroxene garnet amphibolite and so on. The detailed petrological analyses show that these mafic granulites underwent at least four-stage metamorphic evolution. The first metamor-phic stage, the garnet+clinopyroxene+quart mineral assemblage (M1) was probably formed un-der eclogite facies, the second stage, the plagioclase+clinopyroxene symplectite mineral as-semblage (M2) was produced under high-pressure granulite facies by the early decompressive breakdown of M1 mineral assemblage, the third stage, the plagioclase+clinopyroxene+ hypersthene symplectite mineral assemblage (M3) was formed at granulite facies by the late period decompressive breakdown of M1 and M2 mineral assemblages and the final stage, pla-gioclase+hornblende mineral assemblage (M4) was formed by hydrolysis of earlier mineral as-semblages during late uplifting. The detailed mineral composition analyses suggest that garnets and clinopyroxenes within M1 and M2 mineral assemblages display similar compositions to the equivalents in the B and C types of eclogites, whereas the M3 clinopyroxenes are akin to these of the same kind of minerals in the granulite. These mineral chemistry features and P-T estimates calculated by mineral thermometers and barometers indicate that the early stage relic porphyro-blasts (M1) could be formed at the eclogite facies, the early decompressive breakdown (M2) occurred at the high-pressures granulite facies of 1.35―1.48 GPa and 625―675℃, the M3 mineral assemblage recorded the granulite facies of 0.7―0.95 GPa and 775―900℃ and M4 plagioglase+hornblende retrograde mineral assemblage was produced under the amphibolite facies metamorphism with pressure of 0.4 to 0.75 GPa and temperature at between 660 and 700℃. These construct P-T paths from crustal subduction overthickening to tectonic uplift tectono-thermal evolution. The mineral chemical characteristics and P-T condition at every metamorphic stage of these granulites indicate that these rocks experienced the eclogite facies metamorphism during the early stage. Subsequently, these mafic granulites underwent the three-stage exhuma-tion of the eclogite facies tectonic uplift, isostatic uplift related to the transformation from ec-logite/high-pressure granulite to granulite facies and extensional uplift.LIU Shuwen ZHANG Jinjiang SHU Guiming LI Qiugen 2005Science China Earth Sciences2005,48,11:13
3Analysis of the decrease of center pivot sprinkling system uniformity and its impact on maize yield显示文摘Early studies showed that the irregular operations of the center pivot sprinkling system would decrease its uniformity while the reason was lack of discussion.Taking Herman-Hein uniformity coefficient(CUH)and Distribution uniformity coefficient(DU)as evaluation indicators,the reason that irregular operation management and configurations can decrease the uniformity of center pivot sprinkling irrigation was discussed and the impact on maize yield was tested.The reasons for such decrease in uniformity include:(1)With the increase of moving speed,the effect of sprinkling overlaying became worse,which resulted in the lower uniformity of sprinkling irrigation;(2)With the increase of head pressure,the inlet pressure could be adjusted to the same pressure by pressure regulator,which kept the uniformity of sprinkling irrigation constant;(3)When end gun worked abnormally,total head pressure decreased,which led to the decrease of sprinkling irrigation’s uniformity;(4)When pressure regulator worked abnormally,the water flow was subject to great pressure loss,which could decrease the uniformity of sprinkling irrigation;(5)When pressure regulator was uninstalled,significant abnormality of sprinkling irrigation depth occurred,resulting in the decreasing of sprinkling irrigation’s uniformity;(6)Different types of nozzles could produce different uniformity of sprinkling irrigation,which was due to different structures of micro-nozzles;(7)Due to lower uniformity,at the seedling stage of maize,both height and seedling emergence rate decreased.Final yield decreased by 18.35%.This study is important to the proper use and the improvement of configuration selection and field management of center pivot sprinkling system.Li Lianhao Zhang Xinyue Qiao Xiaodong Liu Guiming 2016International Journal of Agricultural and Biological Engineering2016,9,5:6
4Coordinated Multiple Spacecraft Attitude Control with Communication Time Delays and Uncertainties显示文摘In this paper, we consider the coordinated attitude control problem of spacecraft formation with communication delays, model and disturbance uncertainties, and propose novel synchronized control schemes. Since the attitude motion is essential in non-Euclidean space, thus, unlike the existing designs which describe the delayed relative attitude via linear algorithm, we treat the attitude error and the local relative attitude on the nonlinear manifold-Lie group, and attempt to obtain coupling attitude information by the natural quaternion multiplication. Our main focus is to address two problems:1) Propose a coordinated attitude controller to achieve the synchronized attitude maneuver, i.e., synchronize multiple spacecraft attitudes and track a time-varying desired attitude; 2) With known model information, we achieve the synchronized attitude maneuver with disturbances under angular velocity constraints. Especially, if the formation does not have any uncertainties, the designer can simply set the controller via an appropriate choice of control gains to avoid system actuator saturation. Our controllers are proposed based on the Lyapunov-Krasovskii method and simulation of a spacecraft formation is conducted to demonstrate the effectiveness of theoretical results.LI Guiming LIU Liangdong 2012Chinese Journal of Aeronautics2012,25,5:5
5A complete genome assembly of Glaciecola mesophila sp. nov. sequenced by using BIGIS-4 sequencer system显示文摘Using a pyrosequencing-based custom-made sequencer BIGIS-4, we sequenced a Gram-negative bacterium Glaciecola mesophila sp. nov. (Gmn) isolated from marine invertebrate specimens. We generated 152043 sequencing reads with a mean high-quality length of 406 bp, and assembled them using the BIGIS-4 post-processing module. No systematic low-quality data was detected beyond expected homopolymer-derived errors. The assembled Gmn genome is 5144318 bp in length and harbors 4303 annotated genes. A large number of metabolic genes correspond to various nutrients from surface marine invertebrates. Its abundant cold-tolerant and cellular signaling and related genes reveal a fundamental adaptation to low-temperature marine environment.YUAN LiNa REN LuFeng LI YunTao HAN WeiJing YU Yong CHU YaNan LIU GuiMing YU Dan TENG MingJing WANG Liang WANG XuMin ZHOU XiaoGuang YU YuDe YU Jun 2011Science China(Life Sciences)2011,54,9:4
6Microwave-assisted pyrolysis of vegetable oil soapstock:Comparative study of rapeseed,sunflower,corn,soybean,rice,and peanut oil soapstock显示文摘In this study,the effects of catalytic temperature and the type of soapstock on products from microwave-assisted pyrolysis were investigated.HZSM-5 was used as the catalyst to study the pyrolysis of six different soapstocks at 200℃,300℃,and 400℃ catalytic temperature.Results showed that the bio-oil yields initially increased and then decreased with the increase in catalytic temperature.When the catalytic temperature was 300℃,the bio-oil reached up to the maximum value(65.8 wt.%).Findings indicated that the composition of bio-oil was related to the degree of unsaturation of fatty acids sodium in the soapstocks.In the case of saturated fatty acid sodium,a series of alkanes was formed,whereas the pyrolysis of monounsaturated fatty acid sodium resulted mainly in cycloalkanes,the cycloalkenes obtained from bio-oil was produced by polyunsaturated fatty acid sodium.Yunpu Wang Shumei Zhang Qiuhao Wu Dengle Duan Yuhuan Liu Roger Ruan Guiming Fu Leilei Dai Lin Jiang Zhenting Yu Zihong Zeng Xiaojie Tian Xiuhua Yang 2019International Journal of Agricultural and Biological Engineering2019,12,6:3

8Band tillage with fertilizer application for unpuddled transplanting rice in northeast of China显示文摘Many technological innovations have been developed in agriculture for rice cultivation.Farmers still rely on intensive soil tillage,broadcasting fertilizer,excess irrigation water and labor for rice production.Rice cultivation under unpuddled condition in band-tillage(BT)is a new alternative rice cultivation system in the regions where rainfall,fresh water resources,fertilizers and labors are limited.Therefore,the concept of inter-row BT(T-shaped)with row fertilizer application in soils for unpuddled transplanted rice cultivation(T1)was carried out at Fangzheng,Harbin in the northeast of China.The improved system(T1)was compared with traditional practices(T2)in randomized complete block design with three replications.T2 was done with removal of crop residue,full tillage,broadcasting fertilizer and puddled soils by using the conventional machine.Test results showed that all parameters were satisfied and met the requirements of agronomic performances.The variations of fertilizing stability and evenness were 1.84%and 1.72%,respectively.Soil cone penetration resistance was less in T1 than T2 after tillage.Irrigation water was saved by 26.3%in treatment T1 as compared with T2 for wet land preparation,and wet soil resistance depth had no significant difference.Planting depth was significantly different between the treatments which was affected by intensive tillage and puddling in T2 as compared with T1.Soil temperature was nearly similar,but comparatively 0.23°C(on average)higher than traditional system throughout the crop growing season.Crop growth rate and grain yield increased by 8.5%and 5.3%,respectively in band till with fertilizer placed compared to conventional practices of puddled transplanting.The unit production cost(¥/kg of grain yield)was found lower by 12.3%in treatment T1 than T2.The output-input ratio was marginally greater in treatment T1;1.51)as compared to T2;1.32).Short-term findings suggest that inter-row BT system with row fertilizer application could be used in unpuddled rice farming system instead of traditional puddled rice cultivation.Khokan Kumer Sarker Xu Chunlin Wang Xiaoyan Li Minjin Li Lianhao Liu Guiming 2016International Journal of Agricultural and Biological Engineering2016,9,4:2

12The facile method developed for preparing polyvinylidene fluoride plasma separation membrane via macromolecular interaction显示文摘The design of membrane pore is critical for membrane preparation. Polyvinylidene fluoride(PVDF) membrane exhibits outstanding properties in the water-treatment field. However, it is a huge challenge to prepare PVDF macro-pore plasma separation membrane by non-solvent induced phase separation(NIPS). Herein, a facile strategy is proposed to prepare PVDF macro-pore plasma separation membrane via macromolecular interaction. ATR-FTIR and ^(1)H NMR showed that the intermolecular interaction existed between polyethylene oxide(PEO) and polyvinylpyrrolidone(PVP). It could significantly affect the PVDF macro-pore membrane structure. The maximum pore of the PVDF membrane could be effectively adjusted from small-pore/medium-pore to macro-pore by changing the molecular weight of PEO. The PVDF macro-pore membrane was obtained successfully when PEO-200 k existed with PVP. It exhibited higher plasma separation properties than the currently used plasma separation membrane.Moreover, it had excellent hemocompatibility due to the similar plasma effect, hemolysis, prothrombin time, blood effect and complement C_(3a) effect with the current utilized plasma separation membrane,implying its great potential application. The proposed facile strategy in this work provides a new method to prepare PVDF macro-pore plasma separation membrane by NIPS.Juanjuan Liu Xiaolong Lu Guiming Shu Ke Li Shuyun Zheng Xiao Kong Tao Li Jun Yang 2022Chinese Journal of Chemical Engineering2022,35,9:1
13Revealing the correlation between structure evolution and electrochemical performance of high-voltage lithium cobalt oxide显示文摘Lithium cobalt oxide(LCO)is the dominating cathode materials for lithium-ion batteries(LIBs)deployed in consumer electronic devices for its superior volumetric energy density and electrochemical performances.The constantly increasing demands of higher energy density urge to develop high-voltage LCO via a variety of strategies.However,the corresponding modification mechanism,especially the influence of the long-and short-range structural transitions at high-voltage on electrochemical performance,is still not well understood and needs further exploration.Based on ss-NMR,in-situ X-ray diffraction,and electrochemical performance results,it is revealed that the H3 to H1-3 phase transition dictates the structural reversibility and stability of LCO,thereby determining the electrochemical performance.The introduction of La and Al ions could postpone the appearance of H1-3 phase and induce various types of local environments to alleviate the volume variation at the atomic level,leading to better reversibility of the H1-3 phase and smaller lattice strain,and significantly improved cycle performance.Such a comprehensive long-range,local,and electronic structure characterization enables an in-depth understanding of the structural evolution of LCO,providing a guiding principle for developing high-voltage LCO for high energy density LIBs.Jiajia Wan Jianping Zhu Yuxuan Xiang Guiming Zhong Xiangsi Liu Yixiao Li Kelvin H.L.Zhang Chaoyu Hong Jianming Zheng Kai Wang Yong Yang 2021Journal of Energy Chemistry2021,30,3:1
