| 8 | Effects of Grape Seeds and Tea Polyphenols on Serum Enzymatic Indices of Finless Eels ( Monopterus albus )显示文摘[Objectives]This study was conducted to investigate the possibility of adding grape seeds and tea polyphenols to improve the health of finless eels(Monopterus albus).[Methods]Twelve cages were selected in the same water body and divided into 4 groups,each with 3 parallel groups.The control group was fed with common finless eel feed,and the experimental groups were fed with feed supplemented with grape seeds,tea polyphenols,and grape seed-tea polyphenol compound(with a ratio of grape seeds to tea polyphenols at 1∶1),respectively.The feeding amount of each additive was 1%.The experiment was carried out by feeding medicated feed for 3 d and ordinary feed for 3 d,that is,alternately feeding medicated feed and ordinary feed.The experiment lasted for 18 d.[Results]Six serum enzymatic indices were detected after the breeding.The results showed that compared with the control group,the three groups of samples had a certain protective effect on the liver in terms of liver function indices.In terms of immunity evaluation,the tea polyphenol group and the grape seed-tea polyphenol complex group could increase the immunity of eels to varying degrees.In terms of antioxidant capacity,all three groups of samples could increase the body's antioxidant capacity.The results of this study showed that adding tea polyphenols and grape seeds to the feed simultaneously could effectively protect the liver of fish,and simultaneously enhance their antioxidant and non-specific immune functions.[Conclusions]This study provides a reference for the application of the two Chinese herbal medicines,grape seeds and tea polyphenols,in finless eel farming. | Wenhuan ZHU Zhaohui WEI Tianle HUANG Yangzhi LUO Shaomei YU Yiran LIU Shengyuan ZHANG Ping DENG Guizhen DING Hongliang XU Liqiang ZHANG | 2022 | Agricultural Biotechnology2022，11，2： | 0 |
| 9 | Impact of air pressure variations on electrical vehicle motor insulation显示文摘Variation in air pressure severely affects the insulation of electric vehicle(EV)motors,hence weakening the reliability of EVs for safe operation.Nomex‐polyimide‐Nomex,a typical insulation material for EV motors,was used to investigate the motor insulation performance under different air pressures.The results show that the partial discharge inception voltage is significantly reduced for EV motors operated at lower air pressures,and the probability of partial discharge(PD)occurrence is increased.The macroscopic results reveal that the active area of the PD expands at low pressure,while the non‐corroded ring appears in the centre.Additionally,although the number and amplitude of the PD increase significantly with decrease in air pressure,the active area of the PD expands and electrical stress on the insulation per unit area increases slowly.Therefore,when the pressure decreased from 60 to 40 kPa,the endurance life does not show a significant downward trend.Furthermore,the dielectric constant and loss of the low‐pressure samples significantly change during the ageing process,which further indicates critical degradation of the insulation.The aforementioned investigations reveal that the air pressure at different altitudes has a significant impact on the performance of insulation materials. | Peng Wang Chaofan Yu Shakeel Akram Ziyuan Fan Wenhuan Zhao | 2023 | High Voltage2023，8，5： | 0 |

| 12 | Enabling heterogeneous catalysis to achieve carbon neutrality: Directional catalytic conversion of CO_(2) into carboxylic acids显示文摘The increase in anthropogenic carbon dioxide(CO_(2))emissions has exacerbated the deterioration of the global environment,which should be controlled to achieve carbon neutrality.Central to the core goal of achieving carbon neutrality is the utilization of CO_(2) under economic and sustainable conditions.Recently,the strong need for carbon neutrality has led to a proliferation of studies on the direct conversion of CO_(2) into carboxylic acids,which can effectively alleviate CO_(2) emissions and create high-value chemicals.The purpose of this review is to present the application prospects of carboxylic acids and the basic principles of CO_(2) conversion into carboxylic acids through photo-,electric-,and thermal catalysis.Special attention is focused on the regulation strategy of the activity of abundant catalysts at the molecular level,inspiring the preparation of high-performance catalysts.In addition,theoretical calculations,advanced technologies,and numerous typical examples are introduced to elaborate on the corresponding process and influencing factors of catalytic activity.Finally,challenges and prospects are provided for the future development of this field.It is hoped that this review will contribute to a deeper understanding of the conversion of CO_(2) into carboxylic acids and inspire more innovative breakthroughs. | Xiaofei Zhang Wenhuan Huang Le Yu Max García-Melchor Dingsheng Wang Linjie Zhi Huabin Zhang | 2024 | Carbon Energy2024，6，3： | 0 |
| 13 | The Role of Bottom Currents on the Morphological Development Around a Drowned Carbonate Platform,NW South China Sea显示文摘The seafloor around carbonate platforms is largely shaped and modified by downslope processes.However,the role of alongslope processes,including bottom currents,on the morphological development of carbonate platforms remains poorly understood.Here,we use high-resolution multibeam bathymetric data and two-dimensional seismic profiles to investigate the detailed sea-floor morphology around the Zhongjianbei carbonate platform(ZCP)in the northwest South China Sea.A series of depositional bodies and erosional channels are identified to the south of the ZCP and are interpreted as contourite drifts and channels resulted from the interaction between bottom currents and bathymetric features.In addition,active fluid seepages have led to the formation of widespread pockmarks on the seafloor.Importantly,the contourite channels and widespread pockmarks also show a close relationship in their distribution.We propose that the contourite channels around the ZCP are evolved from the coalescence of pockmarks under the persistent erosion of bottom currents.Based on the morphological analysis,we reconstruct the past bottom-current pathways around the ZCP that are parallel to the platform slopes and heading to the south.This study provides new insights into the formation of complex bathymetry and helps understanding how bottom currents and active fluid seepages can influence the morphological development around carbonate platforms. | YU Kaiqi ALVES Tiago M LI Wei LI Shuang LI Jian ZHAO Fang WU Shiguo ZHAN Wenhuan | 2022 | Journal of Ocean University of China2022，21，4： | 0 |
| 14 | Application of Machine Learning Methods in Arrival Time Picking of P Waves from Reservoir Earthquakes显示文摘Reservoir earthquake characteristics such as small magnitude and large quantity may result in low monitoring efficiency when using traditional methods.However,methods based on deep learning can discriminate the seismic phases of small earthquakes in a reservoir and ensure rapid processing of arrival time picking.The present study establishes a deep learning network model combining a convolutional neural network(CNN) and recurrent neural network(RNN).The neural network training uses the waveforms of 60 000 small earthquakes within a magnitude range of 0.8-1.2 recorded by 73 stations near the Dagangshan Reservoir in Sichuan Province as well as the data of the manually picked P-wave arrival time.The neural network automatically picks the P-wave arrival time,providing a strong constraint for small earthquake positioning.The model is shown to achieve an accuracy rate of 90.7 % in picking P waves of microseisms in the reservoir area,with a recall rate reaching 92.6% and an error rate lower than 2%.The results indicate that the relevant network structure has high accuracy for picking the P-wave arrival times of small earthquakes,thus providing new technical measures for subsequent microseismic monitoring in the reservoir area. | HU Jiupeng YU Ziye KUANG Wenhuan WANG Weitao RUAN Xiang DAI Shigui | 2020 | Earthquake Research in China2020，34，3： | 0 |
