| 1 | Statistic Analysis of the Annual Extreme Wave Parameters for the Coast of China显示文摘- According to the need of project design for offshore engineering and coastal engineering, this paper statistically analyses the annual extreme data of waves acquired at 19 observation stations along the coast of China. Five kinds of distribution curves are adopted: Pearson Ⅲ(P-Ⅲ), Log-Extreme I (LE), Log-Normal(LN), Weibull(W) and Exponential r(Eг) to check the adaptability to the long-term distribution of annual extreme of wave in the China Sea areas. The New Curve Fittling Method (NFIT) method and Probability Weighted Moments (PWM) method are used to estimate the distribution parameters and thereby to derive the design wave parameters with different return periods at 19 observation stations. The test results show that by combining Eг distribution and NFIT parameter estimation and optimum seeking by computer, the design wave parameters can be estimated with high accuracy, high speed and high efficiency, and the randomness of the estimated results can be avoided. | Yao, Guoquan Ding, Bingcan Wang, Jianyi Ma, Zhixiong | 1993 | China Ocean Engineering1993,8,1: | 4 |
| 2 | Multi-shell nanocomposites based multienzyme mimetics for efficient intracellular antioxidation显示文摘Oxidative stress is associated with many acute and chronic inflammatory diseases.Development of nanomaterial-based enzyme mimetics for reactive oxygen species(ROS)scavenging is challenging,but holds great promise for the treatment of inflammatory diseases.Herein,we report the highly ordered manganese dioxide encapsulated selenium-melanin(Se@Me@MnO_(2))nanozyme with high efficiency for intracellular antioxidation and anti-inflammation.The Se@Me@MnO_(2)nanozyme is sequentially fabricated through the radical polymerization and the in-situ oxidation-reduction.In vitro experimental results demonstrated that the Se@Me@MnO_(2) nanozyme exhibits multiple enzyme activities to scavenge ROS,including catalase(CAT),glutathione peroxidase(GPx)and superoxide dismutase(SOD).Mechanism researches illustrated that the Se core possesses GPx-like catalytic activity,the Me and the MnO_(2) possess both the SOD-like and the CAT-like activities.What’s more,due to the stable unpaired electrons existing in the nanozyme,the Se,Me and MnO_(2) provide synergistic and fast electron transfer effect to achieve the quickly scavenging of hydrogen peroxide,hydroxyl radical,and superoxide anion.Further in vivo experimental results showed that this biocompatible nanozyme exhibits cytoprotective effects by resisting ROS-mediated damage,thereby alleviating the inflammation.This multienzyme mimetics is believed to be an excellent ROS scavenger and have a good potential in clinical therapy for ROS-related diseases. | Yongjian Ai Jinzhi You Jianyi Gao Jiaping Wang Hong-bin Sun Mingyu Ding Qionglin Liang | 2021 | Nano Research2021,14,8: | 3 |
| 3 | Effect of multiphase content on temperature-dependent electrical conductivity in silicone rubber composites显示文摘To investigate how the multiphase structures affect the electrical conductivity in semicrystalline polymer composites,herein,an accurate multiphase content calculation method is proposed and verified,which combines amorphous phase information in broadband dielectric spectroscopy and crystalline phase information in differential scanning calorimetry.Taken aluminium hydroxide(ATH)filled silicone rubber as an example,it is found that the rigid amorphous fraction(RAF)corresponding to the chains constrained by crystals(RAF_(cry))is not linearly increased with crystalline fraction(CF).Compared to non-isothermal crystallisation,RAF caused by ATH/silicone rubber interface(RAF_(int))after isothermal crystallisation at 213 K changes little,while mobile amorphous fraction and RAFcry is attenuated and CF is strengthened.Based on the calculated structures of ATH filled silicone rubber,activation energy of conductivities during cooling is dominated by the thermal transition for conductive ions and shortened distance among the conductive ions through shrunk volumes of the amorphous phase.Our findings deepen the understanding of multiphase content in semi-crystalline polymer composites and its relationship with electrical conductivity,which can be applied in manipulating electrical performance of semi-crystalline polymers by fillers. | Ying Lin Yuhao Liu Bin Cao Jianyi Xue Liming Wang Jianing Wang Lijian Ding | 2023 | High Voltage2023,8,2: | 2 |

| 5 | Controlling polar-toroidal multi-order states in twisted ferroelectric nanowires显示文摘The toroidal order of electric dipoles in ferroelectric materials has attracted attention in the past decade due to fascinating properties and great potential for enabling novel memory devices,and functional devices in general.However,facile manipulation of toroidal order in ferroelectrics remains challenging.Here,using first-principles derived simulations,we demonstrate an efficient scheme to control the polar-toroidal multi-order(PTMO)states in ferroelectric nanowires.Two feasible strategies of controlling PTMO states by a combination of homogeneous electric field and torque are carried out in ferroelectric/paraelectric composite nanowires.This is possible based on trilinear coupling between polarization,toroidization and the twist force.As a result,switching of the toroidization of the nanowire can be readily achieved by reversal of the axial polarization.The torque threshold needed to control PTMO states is also calculated and found to be relatively small,indicating the feasibility of this method.Our study demonstrates facile control of PTMO states,including ferroelectric skyrmions,in ferroelectrics and is a step towards designing ferroelectric devices based on multi-order states. | Jianyi Liu Ye Ji Shuai Yuan Lili Ding Weijin Chen Yue Zheng | 2018 | npj Computational Materials2018,,1: | 0 |
| 6 | Temperature‐dependent adaptive conductivity coating for surface charge release and electric field control under electro‐thermal coupling field显示文摘Surface charge accumulation is the potential criminal for surface insulation failure on spacers under direct current(DC)voltages.The existence of thermal gradient posing the difficulty of surface charge regulation.This study proposes a temperature‐dependent adaptive conductivity coating technique for surppressing surface charge accumulation under electro‐thermal coupling field.A two‐dimensional axis‐symmetrical simulation model regrading surface charge computation is established.The effects of thermal gradients and coating conductivity on surface charge and electric field distribution are investigated.The results show that the thermal gradient increases the bulk conductive current,therefore aggravating surface charge accumulation.The effects of the coating condcutivity on surface charge and electric field contains three stages.The lower coating conductivity leads to aggravated homo‐polarity charge accumulation.By increasing the coating conductivity,the surface charge and electric field are significantly suppressed at the obtained optimal conductivity,where the bulk and surface conductive current reach a balance stage.Continuously increasing the coating conductivity results in aggravated hetero‐polarity charges.Besides,the increase of thermal gradient to an appropriate extent contributes to the further suppression of surface charge on coated spacers.It is hoped that this study could provide some references for designing highly reliable DC GIL under electro‐thermal coupling field. | Jianyi Xue Zhu Zhang Binbin Li Yushun Zhao Lijian Ding | 2023 | High Voltage2023,8,5: | 0 |
| 7 | College Students’Attitude toward“Chinese+English”Code Mixing显示文摘Code-mixing is a natural phenomenon in multilingual and bilingual communities.As a result of language contact in China,code mixing is on the rise.This paper is devoted to exploring the attitude of contemporary college students towards the linguistic phenomenon of code mixing of Chinese and English.Through online survey and data analysis,this paper finds that the need to speak expressively,to bring forth humorous effect and use euphemism to avoid awkward situation are the first three factors accounting for codemixing.As speakers,they tend to use code mixing of Chinese-English in informal situations with more intimate people;as listeners,they hope such expressions can make humor and make the topic easy.In terms of usage,they are more willing to accept English expressions to avoid some disadvantages.Most of them are remaining neutral on supporting or opposing the code mixing of Chinese and English. | Jianyi Ding Jinglu Zhang | 2020 | Journal of Contemporary Educational Research2020,4,2: | 0 |
